The PCM kills cylinders when misfire malfunctions occur. This is normal operating procedure for an obd2 equipped vehicle. Voltage for both the coils and the injectors in your vehicle come from the fuse box. I hope that this helps.

Can someone help me on locating my c?oling fan switch on my 2003 ford escape.


Cooling fan switch ? The cooling fans on your vehicle are computer controlled . Relay's energized by PCM - engine computer . Coolant temp sensor is a input to the PCM ,when the temp. reaches 212 degress the PCM will energize the low speed fan relay ,if temp reaches 250 degress the PCM will energize the high speed cooling fan relay . Hooking up a scan tool an checking coolant temp. sensor data to the PCM and checking control from the PCM ( energizings relay's ) Is how to diagnose this . Not replacing parts and hope you fix the problem . Your best bet take it to a qualified repair shop.

2005 Chevy trailblazer ext problems 1. Cruise will not set.worked last on 4/12/15 2. While checking fuses for CC problemdome lights stopped working, but worked fine before checking fuses. PLEASE HELP!


Bummer deal! This may be a way to tell you some tail lights are burnt out. Some cruise controls have a fuse in a second location.
The fuse is not in right or is blown. Check with a new fuse. Hope this helps. ...gc http://www.auto-tune-up-and-repair-options.com/

Ford 3.0 no power to coil


The PCM doesn't supply power to the coil's ,it supply's a ground . A fuse supply's B+ power to the coil's . Your vehicle has what is called coil on plug ignition system , a coil for each cylinder . Should have plug wires ,has a spark plug boot . IT is common for these coil on plug system's to fry the driver (transistor) inside the PCM ,if the spark plug gap becomes so worn that the spark can not jump said gap. It shorts inside the coil sending high voltage to the PCM driver . There are video's on youtube showing how to test a PCM driver circuit . Your coil has two wires , one should have B+ voltage an the other goes to the PCM . If your coil fried i look for a short to ground on the control side circuit . This video is for a ford 5.4 l V-8 coil on plug system ,same thing just 2 more coils .

No reverse light, all fuse good. reverse Switch?


It's not that simple anymore . The transmission range sensor switch is what they have now . This range sensor informes the PCM - engine computer what gear the vehicle is in. When you put the gear selector into reverse B+ voltage from the range sensor to the PCM tells the PCM reverse has been selected , the PCM then will energize the reverse lamp relay (located in the under hood fuse/relay box) there by turning on the reverse lamps . There are two fuse's in the under hood fuse/relay box . F27 10amp. & F35 10amp.

05 Ford Escape, coils #3 & #4 not firing. We've replaced the battery, spark plugs, alternator, coil packs, & pcm. Had pcm reflashed. Garage said it had to be coil packs, but just replaced coil packs 3


Check engine light on ? Code's ? What engine ? 2.3 l 4cylinder or 3.ol v-6 This vehicle has coil on plug ignition system , not coil packs ! a coil per cylinder . If new coils an still has no spark , has no B+ voltage to the coil or the PCM isn't controlling them . Without testing i'd only be guessing as to the problem .If the repair shop you had it to can only say it had to be the coils , I'd find another shop to take it to !

  • 2001-2005 ESCAPE 3.0L UNSTABLE IDLE - 2001-2003 ESCAPE 3.0L AUTOMATIC TRANSAXLE SHUDDER - MEXICO ONLY
Publication Date: May 25, 2006
FORD: 2001-2005 Escape
ISSUE: Some 2001-2005 Escape vehicles equipped with a 3.0L engine may exhibit idle speeds outside the specified range. Some 2001-2003 Escape vehicles equipped with a 3.0L engine and CD4E automatic transaxle may exhibit a transmission shudder.
ACTION: Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
  1. If the concern is a 2001-2005 Escape with idle speeds outside the specified range:
    1. Install a new idle air control (IAC) valve with jumper harness included in the kit. The new Denso brand IAC will be installed with the electrical connector facing the opposite direction of the original (Hitachi) valve which is why the jumper harness is required. The original (Hitachi) IAC connector faces the front of the vehicle while the new Denso IAC connector faces toward the rear of the vehicle.
    2. Referring to the calibration charts (Figures 1 and 2), select the applicable file and reprogram the powertrain control module (PCM) using the TSB Service Procedure and WDS/IDS release B40.5 and higher. Calibration files may also be obtained at www.motorcraft.com.
  2. If the concern is a 2001 - 2003 Escape with transaxle shudder, drain, flush and refill the transmission fluid with MERCON® Multi-Purpose Automatic Transmission Fluid. Then, referring to the calibration charts (Figures 1 and 2), select the applicable file and reprogram the PCM using the TSB Service Procedure and WDS/IDS release B40.5 and higher. Calibration files may also be obtained at www.motorcraft.com.
  3. When reprogramming the PCM use blank path programming. Select the proper file from the chart and manually enter the PCM part number or tear tag number to obtain the updated calibration file.
To Perform Blank Path Programming:
  1. Connect WDS/IDS to vehicle.
  2. Select "16 pin", select "All others, except those below", press TICK.
  3. Screen shows installation of cable, press TICK.
  4. Screen shows to turn ignition ON. DO NOT TURN IGNITION ON. Press TICK.
  5. Screen shows progress bar, then screen tells you "No communication can be established with the PCM" and asks you if you want to retry? Select "NO". With the ignition key still OFF, press TICK.
  6. Screen shows to turn ignition ON. Keep ignition in the "OFF" position, press TICK and you will be asked to cycle the key "ON" and "OFF" a few times. Please keep the key position in the "OFF" position through the key cycles.
  7. Screen will show "The diagnostic tester is unable to communicate with this vehicle." You will be prompted to "select a vehicle from the vehicle list", press TICK.
  8. A list of vehicles will be displayed, select ALL OTHERS, and press TICK.
  9. Screen shows "To enable WDS to reprogram the PCM with the correct calibration", enter one of the following: Vehicle Calibration number (7 digits), Tear Tag number (4 digits), or PCM part number, press TICK.
  10. Highlight the box next to the selection chosen, and enter ONLY ONE of the selections listed above. Press TICK.
  11. Follow and answer correctly all remaining screens. Once PCM is reprogrammed communication should be reestablished and PATS system can be reset (if necessary) per Workshop Manual, Section 419-01.

Cyclinder will not fire and I have replaced the coil pack and had the computer checked out


Iam going to answer this with a question.

If you don't work on your own vehicles and you go to a shop that does.

My question is--How does a Shop replace a coil pack and do other diagnostic checks, and give you a vehicle back with a cylinder misfire?
