I can't seem to remember how to get my kj to display the error code on the dash, could someone please refresh my memory.

put the key in the ignition and go off-on-off-on-off-on and it should show where the odo is

This doesn't work on my '03.

ON OFF ON OFF ON.

it will work, the only ones that are susceptible to the dealer TSB reflash that prevents you from pulling the code yourself is '05+

OR you actually have a transmission code.

or, if it doesn't work, you don't have a code. one of the two. when my '02 is CEL-less, it doesn't display anything but hte mileage on the third cycle.

Even when my Jeep was displaying the CEL, I tried the ON-Off-ON-Off-ON trick and it didn't work. When I hooked up my code scanner I got the standard P0442 code for a small evap leak (NO- it wasn't the gas cap! :lol:

).
