Is the EEC-IV module the correct control module for my truck?


Yes, I'm pretty sure an '87 model would be EEC-IV. It was an emissions control system, not a module, and Ford went through the previous generations (EEC-I to EEC-III) during the early '80's with all types of barely-working contraptions.

Just look on the VECI label (Vehicle Emissions Control Information) under the hood. It will tell if it is EEC-IV. If your wiring diagram is for a 1987 model, then you are on the right track. It may be difficult to find an illustration of the ground points. Those are usually only in the Factory Service Manual. And neither Chilton nor Haynes will reproduce that portion of the wiring diagrams. Alldata probably would have it, but that is a subscription service.

Show me timing marks on a 2.9 1990 ford bronco II


2.9liter engine?
there are 2 systems in the book, FSM.
DIS (there is no timing at all , it's fixed by the ECU) end story.

and then.
TFI-IV.
now the 1st quote
  1. Turn the ignition switch OFF.
  2. Disconnect the pin-in-line connector (SPOUT connector) near the TFI module.
  3. Start the engine and measure the voltage, at idle, from the SPOUT connector to the distributor base. The reading should equal battery voltage.
  4. If the result is okay, the problem lies within the EEC-IV system.
  5. If the result was not satisfactory, separate the wiring harness connector from the ignition module. Check for damage, corrosion or dirt. Service as necessary.
  6. Measure the resistance between terminal No. 5 and the pin-in-line connector. This test is done at the ignition module connector only. The reading should be less than 5 ohms.
  7. If the reading is okay, replace the TFI module.
  8. If the result was not satisfactory, service the wiring between the pin in-line connector and the TFI connector.
if the above fails, the ECU can not control spark. timing.

then
underhood VECI label is specific to YOUR truck and should be used if it differs from another source
now the next quote 2

This procedure should not be used as a periodic maintenance adjustment. Timing should only be set after the distributor has been disturbed (removed and re-installed) in some way. If problems are encountered setting the initial timing with this procedure and no mechanical causes are found, follow the spark timing advance check procedure found later in this section.
Do not change the ignition timing by the use of a different octane rod without having the proper authority to do so. Federal emission requirements will be affected.
  1. Locate the timing marks on the crankshaft pulley and the front of the engine.
  2. Clean off the timing marks so that you can see them.
  3. Mark the timing marks with a piece of chalk or with paint. Color the mark on the scale that will indicate the correct timing when it is aligned with the mark on the pulley or the pointer. It is also helpful to mark the notch in the pulley or the tip of the pointer with a small dab of color.
  4. Start the engine and allow it to run until it reaches normal operating temperature.
CAUTION NEVER run an engine in a garage or building without proper ventilation. Carbon monoxide will quickly enter the body, excluding oxygen from the blood stream. This condition will cause dizziness, sleepiness and eventually death.
  1. Once normal operating temperature has been reached, shut the engine OFF.
  2. Firmly apply the parking brake and block the drive wheels. Place the transmission in P(A/T) or NEUTRAL(M/T, as applicable).
  3. Make sure heater and A/C, along with all other accessories are in the OFF position.
  4. Connect an inductive timing light, such as the Rotunda 059-00006 or equivalent, to the No. 1 spark plug wire, according the tool manufacturer's instructions.
  5. Connect a tachometer to the ignition coil connection using an alligator clip. This can be done by inserting the alligator clip into the back of the connector, onto the dark green/yellow dotted wire.
DO NOT allow the alligator clip to accidentally ground to a metal surface while attached to the coil connector as that could permanently damage the ignition coil.
  1. Disconnect the single wire in-line SPOUT connector which connects the control computer (usually terminal 36) to the ignition control module. This will prevent the electronic ignition from advancing the timing during the set procedure.
  2. Using a suitable socket or wrench, loosen the distributor hold-down bolt slightly at this time, BUT DO NOT ALLOW THE DISTRIBUTOR TO MOVE or timing will have to be set regardless of the current conditions.
A remote starter must NOT be used to start the vehicle when setting the initial ignition timing. Disconnecting the start wire at the starter relay will cause the ignition control module to revert to Start Mode timing after the vehicle is started. Reconnecting the start wire after the vehicle is running WILL NOT correct the timing.
  1. Start the engine (using the ignition key and NOT a remote starter to assure timing will be set correctly) and allow the engine to return to normal operating temperature.
  2. With the engine running at the specified rpm, check the initial timing. If adjustments must be made, rotate the distributor while watching the timing marks. Once proper adjustment has been reached, make sure the distributor is not disturbed until the hold-down bolt can be secured.
  3. Reconnect the single wire in-line SPOUT connector and check the timing to verify that the distributor is now advancing beyond the initial setting.
  4. Shut the engine OFF and tighten the distributor bolt while CAREFULLY holding the distributor from turning. If the distributor moves, you will have to start the engine and reset the timing.
  5. Restart the engine and repeat the procedure to check the timing and verify that it did not change
  6. Shut the engine OFF, then disconnect the tachometer and timing light.

and last one more quote "MARKS"
Timing marks consisting of O marks or scales can be found on the rim of the crankshaft pulley and the timing cover. The mark(s) on the pulley correspond(s) to the position of the piston in the number 1 cylinder. A stroboscopic (dynamic) timing light is used, which is hooked into the circuit of the No. 1 cylinder spark plug. Every time the spark plug fires, the timing light flashes. By aiming the timing light at the timing marks while the engine is running, the exact position of the piston within the cylinder can be easily read since the stroboscopic flash makes the pulley appear to be standing still. Proper timing is indicated when the mark and scale are in proper alignment.

and last (open hood, look up, behold the USA fed EPA sticker
clearly stating the timing.
all 89s to present day.

My speedometer not working? is it cause of the after-market radio i put in be the reason.. mitsubishi galant 2002 6 cylinder


So we can rule out the speed sensor and its circuit to the PCM.

I just checked through another area of my database and it seems the speed sensor is systated as on the side of transaxle, near firewall, maybe you can dheck that out to confirm, just out of curiosity and for future reference and some portion of testing requires unplugging the conections.

Anyway I will provide a complete diagnostic pocedures for you to check through and hope an answer is found.

PS. After going through the diagnostic procedure, I believe your radio is the cause of the problem. Refer to # 10

SPEEDOMETER DOES NOT WORK

1. Connect scan tool to data link connector, check for Diagnostic Trouble Code (DTC). If DTC P0500 (Vehicle Speed Sensor) is set, diagnose this DTC first. Go to step 6 . If DTC P0500 is not set, go to next step.

2. On Eclipse, if trip odometer is not working normally, go to next step. If trip odometer is working normally go to step 5. On Galant, if tachometer is not working normally, go to next step. If tachometer is working normally, go to step 5

3. Disconnect instrument cluster connector. Turn ignition switch to ON position. Connect DVOM between ground and instrument cluster connector terminal No. 52 (Black/White wire) on Eclipse or terminal No.29 (Black/White wire) on Galant. If battery voltage is present, go to next step. If battery voltage is not present, check harness connectors and harness wiring between instrument cluster and ignition switch for damage. Repair as necessary.

4. Using a DVOM, check resistance between ground and instrument cluster harness connector terminal No. 34 (Black wire) on Eclipse or terminal No. 30 (Black wire) on Galant. If resistance is less than 2 ohms, replace instrument cluster printed circuit board or speedometer and tachometer. If resistance is greater than 2 ohms, check instrument cluster connector and harness wiring. Repair as necessary. If connector and wiring are okay, go to next step.

5. Disconnect vehicle speed sensor connector and instrument cluster connector. Turn ignition switch to ON position. Connect DVOM between ground and harness side of instrument cluster connector terminal No. 29 (White/Blue wire) on Eclipse or terminal No. 16 (Yellow/Black wire) on Galant. Voltage should be 5 volts. If voltage is okay, repair or replace instrument cluster printed circuit board or speedometer and tachometer. If voltage is not 5 volts, check instrument cluster connector and harness wiring. Repair as necessary. If connector and wiring are okay, go to next step.

6. Disconnect vehicle speed sensor harness connector and connect DVOM to harness side. Check vehicle speed sensor power supply voltage between terminal No. 1 (Black/White wire) on Eclipse or (Black/Blue wire) on Galant and ground. Battery voltage should be present. If voltage is okay, go to next step. If voltage is not present, check vehicle speed sensor harness connector and wiring. Repair as necessary.

7. Using DVOM, check resistance between ground and vehicle speed sensor harness connector terminal No. 2 (Black wire). Resistance should be less than 2 ohms. If resistance is greater than 2 ohms, check instrument cluster connector and harness wiring. Repair as necessary. If connector and wiring are okay, go to next step.

8. Disconnect vehicle speed sensor harness connector. Connect DVOM between ground and harness side terminal No. 3 (White/Blue wire) on Eclipse or (Yellow/Black wire) on Galant. If 9 volts are not present, check vehicle speed sensor harness connector and wiring. Repair as necessary. If 9 volts are present, go to next step.

9. Check harness wiring between vehicle speed sensor connector to radio and tape player connector, auto-cruise control ECU ECM (M/T) or PCM (A/T) connector and instrument cluster connector. If connectors or wiring are damaged, repair as necessary. If connectors and wiring are okay, go to next step.

CAUTION: To prevent damage to scan tool, always turn ignition off before connecting or disconnecting scan tool.

NOTE: If ECM (M/T) or PCM (A/T) is replaced, immobilizer-ECU should also be replaced. Each ECM (M/T) or PCM (A/T) has an encrypted code for immobilizer-ECU, and is registered in immobilizer-ECU.

10. Connect scan tool to data link connector. Turn ignition switch to ON position. Read DTC. Disconnect radio and tape player connector. If DTC P0500 does not reset, replace radio and tape player. If speedometer does not work, disconnect auto-cruise control ECU connector. If DTC P0500 does not reset, replace auto-cruise control ECU. If speedometer does not work, disconnect instrument cluster harness connector. If DTC P0500 does not reset, replace instrument cluster. If DTC P0500 resets when any connector is disconnected, replace ECM (M/T) or PCM (A/T).

What does check dcl mean


DCL is Data Communincations Link... the communication connection between the computers in the instrument cluster and the rest of the car. its usually caused (99% of the time) by a bad connection.

The Data Communications Link (DCL) is a wiring system that allows the sharing of information between the Electronic Engine Control System (EEC-IV) , the Electronic Instrument Cluster (EIC) and external equipment.

The EEC-IV system transmits the following information through the DCL to the EIC:
Engine RPM.
Engine coolant temperature.
EEC-IV malfunction indication.
Fuel used.

The DCL system transmits Malfunction Indicator Lamp (MIL) information to the EIC. The EIC uses MIL information to generate a CHECK ENGINE warning in the event of an engine sensor failure.

The EIC will display the message "CHECK DCL" on its Message Center Display if it is not receiving data from the EEC-IV. This warning is turned off whenever data communication is restored.

The EEC-IV monitors the Data Communication Link for faults. If a fault occurs in data communication a continuous Memory Code is set in the EEC-IV. The DCL Codes (529 for EEC-IV and 533 for EIC) can occur separately or together. These codes are not immediately cleared when data communication is restored.

The existance of a DCL code does NOT mean that a module has failed. also I would check for an oil leak or coolant leak that would be the cause of the smoking under the car.

Check this link for some help on fixing it: http://www.lincolnsonline.com/tech/00086.html

Hope helps.

2000 jeep grand cherokee gauge cluster is working off & on where do i start with troubleshooting?


If it's just the Temp/ Fuel gauge,,, my money is on the instrument voltage regulator. (it governs the voltage to these gauges regardless of the incline (up/down for the fuel gauge) or the battery voltage 12.5 - 13.8 . Other than these it may be an earth connection problen (long shot) because the instrument panel relies on many many signal imputs. !

Hey there,i have a 1991 msuatng LX with the 2.3L ho engine running an 8 plug head. it sounds like i may have a misfire of some sort or my timing may be out but im not sure how to tell, could someone give...


Insert each wire on the proper terminal of the ignition coil. Ensure that the coil boots are fully seated and both locking tabs are engaged. The terminals are identified on the ignition coils. Install wires as shown in the illustration. The 2.3L firing order is 1-3-4-2 for both ignition coil assemblies.

Distributorless Ignition System In the distributorless ignition system (DIS), all engine timing and spark distribution is handled electronically with no moving parts. This system has fewer parts that require replacement and provides a more accurately timed spark. During basic operation, the EEC-IV determines the ignition timing required by the engine and a DIS module determines which ignition coil to fire.

Components
The distributorless ignition system (DIS) for the 2.3L twin spark plug engine consists of the following components:
  • Crankshaft timing sensor
  • DIS module
  • Two ignition coil packs
  • Spark angle portion of EEC-IV
Crankshaft Timing Sensor
The crankshaft timing sensor is a dual hall effect magnetic switch, which is actuated by the dual vane cup on the crankshaft pulley hub assembly. This sensor generates two separate signals, PIP (profile ignition pick-up) and CID (cylinder identification). The PIP signal provides base timing and RPM information, while the CID signal is used to synchronize the ignition coils. Initial timing (base timing) is set at 10 degrees BTDC and is not adjustable. Ignition Coil Packs
Two ignition coil packs are used for the 2.3L dual plug engine. The two ignition coil packs are triggered by the DIS module and are timed by the EEC-IV. Each coil pack contains two separate ignition coils for a total of four ignition coils. Each ignition coil fires two spark plugs simultaneously, one spark plug on the compression stroke and one on the exhaust stroke. The spark plug fired on the exhaust stroke uses very little of the ignition coils, stored energy, and the majority of the ignition coils, energy is used by the spark plug on the compression stroke. Since these two spark plugs are connected in series, the firing voltage of one spark plug will be negative with respect to ground, while the other will be positive with respect to ground. Refer to thePowertrain Control/Emissions Diagnosis Manual for additional information on spark plug polarity. DIS Module
The main function of the DIS module is to switch between ignition coils and trigger the coils to spark. The DIS ignition module receives the PIP and CID signals from the crankshaft timing sensor, and the SPOUT (spark out) signal from the EEC-IV module. During normal operation, PIP is passed on to the EEC-IV module and provides base timing and RPM information. The CID signal provides the DIS ignition module with the information required to switch between the coils for cylinders 1 and 4 and the coils for cylinders 2 and 3. The SPOUT signal (from the EEC-IV) contains the optimum spark timing and dwell time information. The dwell time is controlled or varied by varying the duty cycle (duration) of the SPOUT signal. This feature is called CCD (computer controlled dwell). Therefore, with the proper inputs of PIP, CID and SPOUT the DIS ignition module turns the ignition coils on and off in the proper sequence for spark control. CID is also sent to the EEC-IV micro-processor to allow for Bank to Bank fuel control. Failure Mode Effects Management
During some DIS system faults, the Failure Mode Effects Management (FMEM) portion of the DIS ignition module will maintain vehicle operation. If the DIS ignition module does not receive the SPOUT input, it will automatically turn the ignition coils on and off using the PIP signal. However, this will result in fixed spark timing (ten degrees BTDC) and a fixed dwell time (no CCD). If the DIS ignition module does not receive the CID input during engine cranking, random coil synchronization will be attempted by the module. Therefore, several start attempts (cycling the ignition from OFF to START) may be required to start the engine. If the DIS module loses CID input while engine is running, the module will remember the proper firing sequence and continue to fire to maintain engine operation. Dual Plug Inhibit
Dual Plug Inhibit (DPI) is a function of the EEC-IV that is only used when the vehicle is being started at temperatures -7° C (20° F) and below. During engine cranking, the EEC-IV will only fire the spark plugs on the right hand side of the engine. When the engine has started, the EEC-IV will send a signal to the DIS module to start normal dual plug operation. Ignition Diagnostic Monitor
The Ignition Diagnostic Monitor (IDM) is a function of the DIS module. The DIS module sends information on system failures to the EEC-IV which stores the information for diagnostic self test. The IDM signal also is used to drive the vehicle instrument tachometer, and test tachometer for system

Trying to do the timing of my 302 with TFI. The tag inside the hood says 'Disconnect the in-line spout connector" The manual I have has no reference to the above. Where is this thing located. ??????


There is a single wire connector located near the base of the distributor. I want to say it was a brown wire but my memory isn't good enough to be 100% sure of the color. But it should be fairly easy to find. Just look for the single wore with a plastic connector near the base of the distributor, that will be it. I don't think it actually shows it in any manual, you just kinda have to know what you're looking for. I know, it's tricky but you can do it.

OK,
Have you tried the following:


Ignition Control Module (ICM) REMOVAL & INSTALLATION NOTE: Only the EEC-IV ignition systems use an external ICM. EEC-V systems have incorperated the ICM into the Power Control Module (PCM).
  1. Disconnect the negative battery cable.
  2. Detach the wiring harness connector(s) from the ICM.
  3. Remove the mounting bolts, then remove the ICM. To install:
  4. Position the ICM onto the inner fender apron and install the mounting bolts. Tighten the bolts to 22–31 inch lbs (2.5–3.5 Nm).
  5. Attach the wiring harness connector(s) to the ICM.
  6. Connect the negative battery cable. Fig. 1: Ignition control module and mounting location on the 2.3L, 2.5L engine 89682g32.gif

No spark


I would check the fuses and relay for the EEC IV. You probably have a bad TFI ignition control module, the gray box bolted to the side of the distributor. Auto Zone should be able to test it. Also, check the pick up coil inside the distributor.
