leave ), ( OBDII 96-97, 4 times ) . The check engine light will start to flash yj engine codes quickly with a small pause in between then a medium pause to indicate the next number in the to digit number and then a long pause jeep cherokee obd codes before the next set of flashing for the next code. If all is well you will get a code 55 which would read like this: 5 fast flashes, medium pause then a further 5 flashes. This is how all codes end with is

this 55 code if you have air conditioning or with a code 33 without and any other codes would have been before it separated by a long pause. The codes will remain after this test so you can cycle through it as many times as it takes to read them. After a problem has gone the code will be removed after 50 on off key cycles or if the battery left disconnected over night which will cause a code 12 though. Code Description
Jeep Code 12

It was compiled from a number of different sources. I therefore make no claims as to it's accuracy. This is a work in progress, so if anyone sees glaring omissions or errors, PM me and I will get it fixed. 2) Not all of these codes are relavant to Jeeps, but rather to Chrysler vehicles in general. 3) Computers (in this case the ECU) only do what you tell them, so they might not see problems which do exist, or they might see problems that do not exist, or they might indicate a problem which is in reality caused by some other component.

On 1991 through 1995 models only, the PCM can be placed in the diagnostic mode and the trouble codes flashed on the Check Engine light. The PCM will illuminate the CHECK ENGINE light on the dash if it recognizes a fault in the system. The light will remain lit until the problem is repaired and the code cleared or the PCM does not detect any malfunction for several consecutive drive cycles. To extract the diagnostic trouble codes, perform the following steps: Without starting the engine, turn the ignition key ON, OFF, ON, OFF and ON. The CHECK ENGINE light on the dash will begin to flash. If any trouble codes are stored in the PCM memory, the CHECK ENGINE light will flash the number of the first digit, pause and flash the number of the second digit. For example, Code 23, air temperature sensor circuit would be indicated by two flashes, pause three flashes. A long pause will appear between individual codes if more than one code is present. Carefully observe the flashes and record the exact code number(s) onto paper. After the stored codes have been indicated (or if everything in the self diagnosis system is functioning properly), the CHECK ENGINE light will flash a Code 55. If the ignition key is turned OFF during the code extraction process and possibly turned back ON, the self diagnostic system will automatically invalidate the procedure and must be restarted.
