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).

I need help with a code 12 for. 95 grand Cherokee orvis 5.2l. In need of some help. I know what the code says, but don't understand what it means.


A code 12 just means that memory to the controller has been cleared within 50-100 engine starts, which can occur whenever the battery terminals are disconnected, battery completely dies, etc. Nothing to worry about really, and it is NOT related to the thread that you found.
http://www.jeepforum.com/forum/f11/jeep-cherokee-help-error-code-12-a-1172243/

The codes you found indicate there are no stored trouble codes: Code 12 means that the battery or the computer power lead was disconnected sometime during the last 50 operating cycles. This is not an indication of a problem. Code 55 means that there are no other stored codes in the computer.

87 fiero gt code 12


Code 12 doesn't need fixed. When you begin to test codes you will get the code 12 but that is just telling you that it is in diagnostic mode, it will flash the code 12 three times, then after that it will flash all stored trouble codes. After all stored trouble codes have been displayed, the ECM will repeat the process( so getting code 12 again means you have reached the end of the stored codes list) If it displays code 12 three times and then displays code 12 again , it means you have no problem codes.

Need trouble codes for 1993 Cadillac F31 F47


prev.gif next.gif Reading Codes OBD-I Systems Fig. 1: Diagnostic trouble codes — 4.5L engine 84204010.jpg
Fig. 2: Diagnostic trouble codes — 4.9L engine 84204277.jpg
Fig. 3: Diagnostic trouble codes — 4.6L engine 84204442.jpg
Listings of the trouble codes for the various engine control systems covered in this manual are located in this section. Remember that a code only points to the faulty circuit NOT necessarily to a faulty component. Loose, damaged or corroded connections may contribute to a fault code on a circuit when the sensor or component is operating properly. Be sure that the components are faulty before replacing them, especially the expensive ones. The Assembly Line Diagnostic Link (ALDL) connector or Data Link Connector (DLC) may be located under the dash and sometimes covered with a plastic cover labeled DIAGNOSTIC CONNECTOR.
  1. On all 1990–95 models the diagnostic trouble codes can be read by grounding test terminal B. The terminal is most easily grounded by connecting it to terminal A (internal ECM ground). This is the terminal to the right of terminal B on the top row of the ALDL connector.
  2. Once the terminals have been connected, the ignition switch must be moved to the ON position with the engine not running.
  3. The Service Engine Soon or Check Engine light should be flashing. If it isn't, turn the ignition OFF and remove the jumper wire. Turn the ignition ON and confirm that light is now on. If it is not, replace the bulb and try again. If the bulb still will not light, or if it does not flash with the test terminal grounded, the system should be diagnosed by an experienced driveability technician. If the light is OK, proceed as follows.
  4. The code(s) stored in memory may be read through counting the flashes of the dashboard warning lamp. The dash warning lamp should begin to flash Code 12. The code will display as one flash, a pause and two flashes. Code 12 is not a fault code. It is used as a system acknowledgment or handshake code; its presence indicates that the PCM can communicate as requested. Code 12 is used to begin every diagnostic sequence. Some vehicles also use Code 12 after all diagnostic codes have been sent.
  5. After Code 12 has been transmitted 3 times, the fault codes, if any, will each be transmitted 3 times. The codes are stored and transmitted in numeric order from lowest to highest. NOTE: The order of codes in the memory does not indicate the order of occurrence.
  6. If there are no codes stored, but a driveability or emissions problem is evident, the system should be diagnosed by an experienced driveability technician.
  7. If one or more codes are stored, record them. Refer to the applicable Diagnostic Code chart in this section.
  8. Switch the ignition OFF when finished with code retrieval or scan tool readings. NOTE: After making repairs, clear the trouble codes and operate the vehicle to see if it will reset, indicating further problems.

4x4 light is flashing (TOD indicator)


this means there is a problem if it continuosly flashes
Short-circuit terminal 8 of the self-diagnostic
connector to GND to display the trouble code on the
CHECK lamp.
If no trouble codes exist, code “12” is displayed continuously.
If trouble codes exist, code “12” is displayed three times, and then other trouble codes, starting from the smaller code number, these are displayed three times respectively.

this is located behind right front centre console side trim..
