Buy the manual, hard copy, for well over $100. Its quite the multi-page affair. You may be able to see a page or three for free on an online side.
Or buy the CD-ROM manual WITH wiring diagram (double check this with the ventdor). BUT- you need to run a small batch program to use it on a Win11...
Today I installed a brand new TIPM (from MAKS), preprogrammed for my VIN (took approx 30 minutes). The car runs fine.
Now we get to see what happens on successive days - if the electrical gremlins are still in the engine bay - or not!
It seems to be a problem only on the first drive of the day; i.e., after sitting overnight. But not always - currently about 50% of the days are affected. Jeep is in garage overnight - which is not cold.
After two weeks of motoring bliss, the limp-mode problem is back. This first news instance - the battery disconnect trick cleared the problem (and any codes).
After being turned away for a service request (diagnosis, actually) by local Jeep Chrysler dealer who said "we don't work on vehicles over 10 years old" I today called Jeep's corporate customer service. The policy of what age at which a vehicle can be declined for service is left up to the...
One of the ball-head studs popped out of its "L" bracket, it was not properly swedged (?) into its "L" bracket. So I replaced it with a 5/16 threaded shank ball-head from Amazon. This required drilling out the hole in the "L" bracket to 5/16"
Update: the problem refuses to return.
I did finally identify the correct YL/BR wire, and examine its voltage. Voltage is high if things are working normally, same on the YL/OR wire. So now I have a baseline for voltages on the two main wires involved in the P0882 code.
Funny thing is, when...
I don't think I did anything useful disassembling the TIPM, other than confirm that the only relay involved is at the level of the fuses, there is no internal relay in the affected circuit (only a solid-state driver)
Update:
as I said, the TIPM's plug-in relay on top tested ok (and I also swapped it with another relay). There is no internal micro-relay driving the on-top relay, the driver is solid state. The on-top fuse is also good.
I removed and disassembled the TIPM - found nothing obvious.
After...
P0882 Symptoms and Considerations
Symptoms etc.
First started in Idaho in April-May - in the cold and at altitude
Now occurs at high or low altitudes
Used to be triggered by cold weather (not so much any more)
Typically occurs on the first trip of the day - after cooling down overnight...
The saga continues. Most recently it did the same thing, put itslef into Limp Mode first thing in the morning after being fine prior and 60+ deg F overnight (i.e., toasty) - without turning oit off I dorve it to the dealer at less than 60 mph I had an appointment) and turned it off in their...
