Hello, I'm looking for a replacement for my jeep cherokee 99, the current part number is Chysler P56041 629AD, I found a Chysler P56041 278AD, can this computer works ok with my cherokee?


THE PCM MODULE.
no country stated, the 728ad shows Europe. (why?)
"I found"

where, at ebay, at pick-apart, or ?
USA cars have 11 PCM for one engine. fact.
and 100s more world wide.
what a question, just a p/n
then you post to grand Cherokee and then text leaving out Grand.?
why?
i searched the part at jeep and is wrangle part, 629ad.

you do know that it must be reprogrammed to your car right:?
the pcms on cars can vary
by engine, trans opted , 4wd/2wd,and year.
federal PCM
Calif PCM
and mexico PCM
and 9 more. just for 1999

is yours 42RE for 45RFE?? tranny??? 30/32 RH? what?
post county (or state if calif)
post engine and year
post body and not contradict.?
post drive line, in car, tranny and if 4wd?
then we can match it up
or call jeep.com

they (jeep) will do this magical thing!
ask you the VIN.
and then look it up in their database.
and see ALL THE ABOVE even what radio is in it. of 5.
me, im a glass half full guy (hard knocks, reality stuff)
id not even believe the part in car is correct.
im too SAVVY !
i find out from jeep what it should have first.

not one matches the 4.0L in the GC.


the 629 posted shows this at jeep.com

It sounds like you either have an Electrical Issue with the PCM or your Band is slipping and you are looking at a rebuild sometime soon.

Hazards not working on 1998 jeep cherokee


Look in your owners manual for the location of the fuse panel. Thereis one under the hood and another under the dash. I believe it's on the left side. More than likely it's a blown fuse.

I can't start my 1998 Grand Cherokee 4.0L. it would barely start for weeks but i always managed to get it started until now i tested the battery and the starter which both passed. any sugestions would be...


this is an epidemic for jeeps built from 1993-1998-the problem is possibly your PCM which is your vehicle's computer-it is located right behind the radiator overflow jug on the passenger side-there are poor connections inside the PCM and the 3 wiring harnesses conected to it and jeep/chrysler did a poor job connecting the unit securely to the fire wall-if the vechilce would stall durinng driving or even in park or at idle and became worse and worse then you can bet 100% its the PCM..you can try wedging a piece of styrofoam or somthing of that nature in-between the PCM and overflow jug-(basicly just tightening the wiring conects to the PCM)-see if it will start then-if it does start wiggle the PCM around and if the vehicle stalls thats your problem...the wedge between the jug and PCM should work,but it is a temp fix and basicly a "jurry rig" you will eventually need to get a new PCM-you can find them on e-bay for a decent price,100.00 to 200.00 dollars but you must make sure the numbers on your old PCM and the one you purchace are IDENTICAL-if the wedge wont work your PCM connections are probably too far gone or possibly a different problem all together. go get your codes read at a local autozone or checker/o'reilly they usually do it free.
