Jeep Cherokee Instrument Cluster Self Test Diagnosis II

Same as the other Self Test Diagnosis with parking lights on.

This is a self test of the instrument cluster functions on 1998 and newer Jeep Cherokee's XJ and Jeep Wrangler's TJ. Here is the procedure:

1) Push and hold the odometer reset button.

2) Insert the key into the ignition and turn it to the Run position, but don't start it.

3) Release the odometer reset button.

It will enter the self test mode. The gauges will start moving in a certain sequence and also most of the indicator lights will turn on. Also the odometer will display all the numbers.

In some cases, if there is a stored code, or if the Check Engine Light is activated, the Error Code will be displayed in the Odometer after it finishes the test.

what year is this jeep? I have a 99 cherokee xj. and I can get the test for gauges to work fine. but i am trying to figure out this obd code thing. I know the computer has history codes in it from a recent check engine light that i did not clear. but i do this and it shows no code after. Also i tried the old key tricks that work for other cherokees and it shows nothing again. Even if no codes its supposed to show a 55. i get nothing.

@dmhhs05 Well, mine doesn't displays the code, even if I intentionally create a false code like disconnecting some sensor while the engine is running. I don't know why, but apparently doesn't works on all years. You may retrieve the code with an OBD II compliant scanner.

how long do i hold down the button for?

[jomelmaldonado]

Until you insert the key into the ignition and turn it to the Run position.

and does my car have to be on or just click b4 starting it?

[jomelmaldonado]

With the engine off, push and hold the odometer reset button. Then insert the key into the ignition and turn it to the Run position, but don't start it. Finally release the odometer reset button.

I find it horse shit that the CHEROKEE does this but not the GRAND CHEROKEE.....

[jomelmaldonado]

No, it won't reset the mileage. It only test the gauges functions.

[webmike720]

if i do that, will my jeeps computer relearn it's programs? it will not restart my mileage?
