Code 12 is a normal code when the engine is not running. it means there is no distributor reference. When this code flashes during the key cycle, it is normal.

    Code 33 = AC clutch relay circuit. An opened or shorted condition was detected in the AC relay circuit. This could be the relay itself, a fuse or the AC clutch wire or clutch assembly is defective. Check all connections before replacing anything.
    Code 41 = Generator field not switching properly. This could be an open or short condition in the generator field control circuit. Test the battery voltage output of the alternator and verify the connections are clean and tight. Check fuses also. Replace the Atlernator if found that it is not be putting out correct voltage and Amperes while the engine is running.
    Code 55 = End of message (codes)

  • GetMeOttaHere Sep 08, 2010

    Code 33 will NOT cause the check engine light to light.
    Code 41 WILL always light the engine light.

  • GetMeOttaHere Sep 08, 2010

    Correction...Code 12 means direct battery input to the PCM (computer) was disconnected within the last 50 key cycles. Again, this code is ok and will go away after 50 key cycles.

SOURCE: 1994 Toyota 4Runner V6 2.0 VZE Engine, Automatic,

that code is for rpm signal and possible causes are the distributor wire harness from dis. to ecu (engine computer) or ecm itself! do you have rpm tach working on the dash? if so it might have seen the fault for a few seconds and set the code if you don't have rmp tach then you need to diagnois the cuase by testing the signal out of the dis. then down the line! if you have any more question please ask. good luck

I have a 1996 dodge intrepid with a diagnostic code 1255. Could someone please tell me what that code means?


If you had two blinking CEL codes, a 12 (pause) and a 55, the code 12 means the battery has been disconnected within the previous 50 starts. The code 55 indicates the end of stored codes. Therefore, you have no saved trouble codes (disconnecting the battery deletes saved trouble codes).

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

Where is the obd2 connector location on holden ra rodeo v6


isuzimpuls.gif
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).

What is service engine light code 12 mean



READING CODES USING MIL (CHECK ENGINE) LAMP

Be advised that the MIL or CHECK ENGINE light can only perform a limited number of functions and it is a good idea to have the system checked with a scan tool to double check the circuit function.

  1. Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
  2. Count the number of times the MIL (check engine lamp) on the instrument panel flashes on and off.

The number of flashes represents the trouble code. There is a short pause between the flashes representing the 1st and 2nd digits of the code. Longer pauses are used to separate individual 2-digit trouble codes.
An example of a flashed DTC is as follows:


Lamp flashes 4 times, pauses, then flashes 6 more times. This denotes a DTC number 46. Lamp flashes 5 times, pauses, then flashes 5 more times. This indicates a DTC number 55. DTC 55 will always be the last code to be displayed.

What is troulbe code 12 And 55 on 1995 misubishi eclipse


ok code 12 means that you disconect battery recently, maybe you were trying to clear trouble code by doing that, in worst case just replace the battery not a big deal

Code 55 means "no Trouble codes found" code 55 means that thats the end of self testing codes, there is no mode code. just ignore code 55.

im pretty sure you were doing a selft testing dtc bye turning switch on and off.

1994 Chevrolet 2500 Trouble codes. I have a 94 Chevy 2500, it flashes error 3 across the dummy screen with the truck mileage. I hooked it up to a diagnostic code reader, I got the following codes: 12:...


DTC 12 -
When terminals "A" and "B" have been connected, the ignition switch turned to the "ON" position with the engine not operating, the MIL (Service Engine Soon) should flash DTC 12 three times consequently. This will be the following flash sequence: "flash, pause, flash-flash, pause, flash, pause, flash-flash, pause, flash, pause, flash-flash." DTC 12 indicates that the control module diagnostic system is operating properly. If DTC 12 is not indicated, and a fault is present within the diagnostic system itself, it should be addresses by consulting the appropriate diagnostic chart in this section.

The MIL (SES) will indicate a diagnostic trouble code (DTC) three times if a DTC is present, or it will simply continue to output DTC 12. If more than one DTC has been stored in the control module memory, the DTC(s) will be displayed from the lowest to the highest with each DTC being displayed three times.



DTC 32 - Exhaust Gas Recirculation (EGR) Error
EGR open command did not change the fuel mixture when the command was given during off idle operation. EGR opening should cause the mixture to be slightly richer because of the low oxygen content of the exhaust gas. EGR position signal is also monitored to verify EGR movement.

The EGR relies on a certain amount of exhaust back pressure to work properly. Now that you have lowered the back pressure, it can't work. Have you tried a new EGR valve? You may need a service manual with an EGR diagnostic chart to make sure, but I think the duals are the problem. Plus the O2 sensor is only looking at one side of engine instead of both.

Keep in midn this procedure to Clearing Diagnostic Trouble Codes:
To clear the DTC's from memory of the control module, either to determine if the malfunction will occur again or because the repair has been completed, the Tech 1 Scan Tool should be used to clear the DTC's. If a Tech 1 Scan Tool is not available the following must be perform'd when all repairs have been completed. This will allow all DTC's to be cleared:
1. Ignition "OFF."
2. Ground diagnostic terminal "A" to "B" of DLC (Data Link Connector).
3. Ignition "ON."
4. Fully apply brake pedal.
5.Fully apply accelerator pedal.
6. Check MIL (Service Engine Soon) for DTC 12.
7. Release brake pedal.
8. Release accelerator pedal.
9. Check MIL (Service Engine Soon) for DTC 12.
10. Turn ignition "OFF."
11. Remove Jumper from DLC connector.

NOTICE: To prevent control module damage, the key must be "OFF" when disconnecting or reconnecting module power.

Good luck.
