What year is it? On my 94 their is a way to turn the key in a certain way and you get the check engine light to blink a code that tells you what is wrong. I have also heard of autozone or somewhere similar having a scan tool to get the codes.

if u take it to autozone they will read the code for u for free and try to help u out and diagnosis the problem

ok..well i went out and just did the on-off, on-off, on thing and the check engine light started flashing. do i count the total number of flashes or what??

it will flast a series of times, like flash-flash-flash....then it'll wait like 3 seconds, then flash-flash....then wait 3 seconds......the flash-flash-flash-flash. that would be 324.

look online to find what it is...not that you have a DTC of 324...that would be weird

[iwishihad1]

will it only do the series once...because it seemed like if it didn't my number would be something like 1, 3, 2, 5 6

im definately not getting any kind of 3 second pause..how many digits are supposed to be in the code at MAX. im thinking mines around 4-5 maybe 6 digits long

[severous01]

oh, and they'll only do OBD2 or 96+ cars...not the older ones...sorry.

wait so on my 95 cherokee it wont do the flash thing cause my check engine light comes on all the time and i dont know how to check it to see what it wants me to check. what do i do (if there is anything i can do) to check it?
Thanks,
Jack

I'm hopefully not trying to pirate a thread but I think I speak for some of us when I say can we have the different ways to do this on different systems.


I've tryed the key thing on my 99 and it doesn't work and I'd like to know what I'm doing wrong

you have an obd2 system, you'll need a scanner...that's all, no switches or throttle...high beams or nothing...scanner, that's all

as for the other guy, it will be 3 digits, and the pause is 1.5 seconds between flash to flash, and a 3 second wait between numbers. one set of flashes is the first number, after the 2-3 second wait is the second number, and then another 2-3 second wait for the third.

about this much time between flashes....hits head
about this much time betwen numbers.....drool hits ground.

I have posted this link so many times, Go Jeep is probably getting tired of it.
