Connect white (test lead) and black (ground lead) wires that are branched from harness approximately eight inches from ECM. After leads are grounded, the "Check Engine" light will flash the diagnostic trouble codes. The DTC's are indicated by the flashing CEL.
FLASH, FLASH, pause, FLASH, FLASH, FLASH = Code 23.
If only one diagnostic trouble code is stored, the DTC will repeat continuously until test leads are disconnected. If more than one diagnostic trouble code is stored, each DTC will repeat three times, starting with the lowest, then proceed to the next DTC. After all DTC's have been displayed, the pattern will repeat.I-MARK 84-85
Connect male and female test leads taped into wire harness near ECM. After leads are connected, the "Check Engine" lamp will flash the trouble codes. The DTC's are indicated by the flashing CEL.
FLASH, FLASH, pause, FLASH, FLASH, FLASH = Code 23.
If only one diagnostic trouble code is stored, the DTC will repeat continuously until test leads are disconnected. If more than one diagnostic trouble code is stored, each DTC will repeat three times, starting with the lowest, then proceed to the next DTC. After all DTC's have been displayed, the pattern will repeat.
86-87 Impulse located near the ECM connector, is used to actuate the Engine Control Module (ECM) trouble code memory within the module. Two terminals (A and C) of this connector are used to activate the diagnostic trouble code system in the ECM. With the ignition switch turned On, engine Off, connect a jumper wire between terminals A and C. The "Check Engine" lamp will begin by flashing a DTC 12. DTC 12 = flash, pause, flash, flash. There will be a longer pause and a code 12 will repeat two more times. This code indicates the self-diagnostic system is operating. The cycle will then repeat until the engine is started or the ignition is switched Off. In most cases, DTC's will be checked with the engine running since no DTC's other than DTC 12 or 51 will be present without the engine running. Remove jumper wire from ALDL connector before starting engine. Reconnect jumper wire after engine is running.

Throttle Body Fuel Injection

The ECM test connection is located under the center console.
A built-in, self diagnostic system will identify problems in the throttle body fuel injection system. When a problem is detected, the diagnostic system will illuminate the "Check Engine" light.
When the engine is started, the Check Engine light should turn off.. If the light remains lit, the self diagnostic has detected a problem. To determine where the problem exists, ground the "Test" terminal of the connector with the ignition On, engine Off and watch the check engine light. Each DTC will flash three times (lowest to highest).

The engine block indicator is on when engine running and only 2 sparks firing. loss of power.


the engine block indicator might be the computer check engine lamp. go to the local parts supply store that offer to plug into the computer to extract engine trouble codes. wright down all trouble codes. the trouble codes is only a guide for further trouble shooting.

Mis fires


The engine in your car is designed to run smoothly with maximum power output and produce as minimal emissions as possible. When your car's engine is not performing properly it can cause, low gas mileage, low power output, increased emissions and possible internal engine damage if left untreated. This troubleshooting guide is designed to isolate the malfunctioning cylinder and troubleshoot to repair the problem. Before we start we need to know one of two things; is the engine running poorly at idle only and seems to be ok under power? Or does the engine run fine and it's just the engine idle condition that is the problem. If your engine is idling rough please visit, engine misfires at idle If your engine cranks over but won't start visit engine wont start. If your engine won't crank over visit engine wont crank over. If your engine is running rough all of the time or intermittently you are in the right place. Below we have created a guide to aid diagnoses and repair procedure for most common rough engine running problems.

  • Step 1: Anytime you have a problem with electronically controlled components such as an engine, transmission, ABS brake, or SRS (supplemental restraint system, air bag) inspect all fuses in the under hood power distribution center and under dash fuse panels using a test light. If all fuses test ok continue to the next step.
  • Step 2: To check for problems with electronically controlled components such as an engine, transmission, ABS brake, or SRS (supplemental restraint system) and the fuses test ok a trouble code scan is needed to identify any system trouble. Use a simple scanner tool to retrieve trouble codes and check if they relate to the specific problem, like an ignition coil failure code. If a trouble code is present but does not pertain to the immediate problem like an EVAP code ignore it until a later time, after the engine is running properly. The reason we repair non-related codes after the engine is running properly is because sometime false codes can be triggered by a rough running engine. Once the engine is running properly the code present might cycle and turn itself off. You might say "if the engine isn't running right shouldn't it have a check engine light and a trouble code?" Sometimes conditions occur that will not be detected by the computer, example: if the intake or exhaust valve operation fails the computer cannot detect the failure because the problem is not sensor related, so the engine doesn't run smooth and the computer thinks everything is ok with no codes. If the trouble code retrieved relates to a cylinder misfire like an injector driver or ignition coil failure first repair these problems then re-test system. If no trouble codes are present proceed to the next step.

We just picked up a 1985 Cadillac Deville with 42,000 original miles. The car had not been driven in 4 years. It was given a tune up, all liquids were changed. When we changed the gas filter there was...


Yes, water could be in the gasoline. Try to run a few tanks of gas through it to clear up that problem.

Are there any engine codes on this car that are readable? Maybe a throttle position sensor is not giving good data to the computer.

BASIC TROUBLESHOOTING
  1. NOTE: The following explains how to activate the Trouble Code signal light in the instrument cluster. Before suspecting the C-4 or CCC system, or any of its components as being faulty, check the ignition system (distributor, timing, spark plugs and wires). Check the engine compression, the air cleaner and any of the emission control components that are not controlled by the ECM. Also check the intake manifold, the vacuum hoses and hose connectors for any leaks. Check the carburetor mounting bolts for tightness. NOTE: For information regarding computer control/troubleshooting of the Electronic and Digital fuel injected vehicles, please refer to Section 5 of this manual. The following symptoms could indicate a possible problem area with the C-4 or CCC systems:
    1. Detonation
    2. Stalling or rough idling when the engine is cold
    3. Stalling or rough idling when the engine is hot
    4. Missing
    5. Hesitation
    6. Surging
    7. Poor gasoline mileage
    8. Sluggish or spongy performance
    9. Hard starting when engine is cold
    10. Hard starting when the engine is hot
    11. Objectionable exhaust odors
    12. Engine cuts out
    13. Improper idle speed (CCC only). As a bulb and system check, the Check Engine light will come on when the ignition switch is turned to the ON position but the engine is not started. The Check Engine light will also produce the trouble code/codes by a series of flashes which translate as follows: When the diagnostic test lead (C-4) or terminal (CCC) under the instrument panel is grounded, with the ignition in the ON position and the engine not running, the Check Engine light will flash once, pause, and then flash twice in rapid succession. This is a Code 12, which indicates that the diagnostic system is working. After a long pause, the Code 12 will repeat itself two more times. This whole cycle will then repeat itself until the engine is started or the ignition switch is turned OFF. When the engine is started, the Check Engine light will remain on for a few seconds and then turn off. If the Check Engine light remains on, the self-diagnostic system has detected a problem. If the test lead (C-4) or test terminal (CCC) is then grounded, the trouble code will flash (3) three times. If more than one problem is found to be in existence, each trouble code will flash (3) three times and then change to the next one. Trouble codes will flash in numerical order (lowest code number to highest). The trouble code series will repeat themselves for as long as the test leads or terminal remains grounded. A trouble code indicates a problem with a given circuit. For example, trouble code 14 indicates a problem in the cooling sensor circuit. This includes the coolant sensor, its electrical harness and the Electronic Control Module (ECM). Since the self-diagnostic system cannot diagnose every possible fault in the system, the absence of a trouble code does not necessarily mean that the system is trouble-free. To determine whether or not a problem with the system exists that does not activate a trouble code, a system performance check must be made. This job should be left to a qualified service technician. In the case of an intermittent fault in the system, the Check Engine light will go out when the fault goes away, but the trouble code will remain in the memory of the ECM. Therefore, if a trouble code can be obtained even though the Check Engine light is not on, it must still be evaluated. It must be determined if the fault is intermittent or if the engine must be operating under certain conditions (acceleration, deceleration, etc.) before the Check Engine light will come on. In some cases, certain trouble codes will not be recorded in the ECM until the engine has been operated at part throttle for at least 5-18 minutes. On the C-4 system, the ECM erases all trouble codes every time that the ignition is turned off. In the case of intermittent faults, a long term memory is desirable. This can be produced by connecting the orange connector/lead from terminal S of the ECM directly to the battery (or a hot fuse panel terminal). This terminal must always be disconnected immediately after diagnosis as it puts an undue strain on the battery. On the CCC system, a trouble code will be stored until the terminal R at the ECM has been disconnected from the battery for at least 10 seconds.

Need to pull and reed trouble codes for a 1989 honda


there is a jumper wire on the passenger side kick panel, short this wire with a paper clip and turn your ignition to run, the CEL check engine light will flash the number of the trouble code,
long flashes = 10's
short flashes = 1's
so a code read like this
L<L<L<S<S<S<S<S
would be 35
there will be short pauses between flashes and a long pause between separate codes,
hope this helps
