TIPM issues, again

I find it hard to believe that a new box would display the exact same flaws of the one it replaced. I'd be checking wiring harnesses and all connections on the next go-around.

Correct. That's what puzzled the shop owner also. However, it's also puzzling that if it was a different cause it would take several months to manifest, the same way, again.

Anyway, he plugged the analyzer to the OBD port and managed to repro the fault. This time he was tracking it through his device and reading the codes.

What got him even more puzzled is that the issue is causing the engine to stall and shut down. He did not see any error codes pointing to that, mostly related to the wiper's control. So, he kept my Jeep and will rerun everything again.

So, the question is what can be messing the TIPM and shutting down the engine. Whatever it is, goes away when we reboot by disconnecting the battery but can come back anytime.

Whatever it is, the wipers are the telltale.

Quick update on this one for whoever is interested.

Took my Jeep to a different dealer where the technicians were also puzzled.

After a full day of tests they called saying it was the wipers module that was bad. Somehow during its "tantrums" causing an overload on the TIPM, which then would shut the engine down.

I was a bit flabbergasted and asked them to confirm how could a bad wipers' module cause an engine shutdown and they confirmed. And apparently Chrysler is aware of this potentially deadly issue (and does nothing?).

So, be aware.

A small fortune later (also did some software updates on the ECU and ABS) the Jeep seems to be working OK again. Hopefully this time for good.

Cheers!

Main reason why i can't stand vehicles controlled by computers and looking at the new JL seems like that thing is pretty computer controlled with all the new things available for it.

It appears we need to go pre-2007 if we want something that will not be killed by a failing onboard computer. The Jeeps became like any other car in this aspect. No extra reliability or fail-safes.

Hi All,

So, my JKU has TIPM issues again, after having it replaced just a few months ago by a new one and around $1000 less in my wallet.

The wipers' creeping by themselves are back and now it seems worse because just by turning them on when things are working fine can kill the engine.

Luckily that was in the parking lot. It was raining, I got in, turned engine on, turned wipers on, engine died. Only came back after the usual battery disconnect reboot.

The issue also shows up even when the wipers are not on. They start creeping slowly and I kill the engine if I turn the control knob on. Sometimes takes several "reboots" before the engine works again.

I'm on my last straw and really appreciate your help and hints. Cannot live with a vehicle behaving so unreliably.

Thanks!



I don’t understand why you went to a electronic store. Sure they’ll tell you what’s wrong. Why not go to a local guru Jeep automotive shop and get it fixed the right way. Just my 2¢. Also why go back to the Dealership. I’ve never had my JK serviced by the dealership. They charge too much money.

No worries.
I did not get back to the same dealer. The first one showed to be completely incompetent.
I then took my Jeep to an electrical shop. The owner detected the TIPM failure with his equipment but it would not show the wiper module failure, hence he told me only a dealer could do the deep scan with its proprietary equipment.
I then took it to a different dealer that another friend recommended.
This dealer was the one that diagnosed the wipers' controller failure and explained it can indeed lead to the TIPM shutting down the ECU (killing the engine).

So, less than two months since the dealer said they detected the issue (wipers control comms module) my Jeep is showing the same symptoms again.

Wipers start by themselves and kill the engine. I'll take it back but no longer having any hopes.

Very, very close to get a 4Runner.

you've had the clock spring and wiper control module changed out once already?

I think I may have said this before on your prior thread, but it's got to be a short in the wiring, a bad ground, or a bad connection in the harness.

Boards rarely go bad just because and, in my line of work, are typically the last thing to be replaced. If symptoms persist or boards really do burn out or malfunction, it's almost always due to wiring or an external sensor.

Good luck getting this figured out. I know it's gotta be frustrating as hell.

Thanks! This is the same thread that I "resurrected" because the issue came back.

I agree that it's weird that this thing is failing like that and exactly the same issue. The dealer was pretty sure of the wiper module after keeping the Jeep for tests for a few days.

Any advices on how to track the harness for problems? I'm afraid I'll have to end-up doing it myself.

Disclaimer: I'm an HVAC tech, not a Jeep tech. That being said, troubleshooting is troubleshooting. 😎

First, I'd Google around to see if anyone else had and solved this issue.

Then I'd scan the computer to see if any codes are being thrown and see if anything can get you closer to the issue.

Next I'd check all the wires going between the wiper module and the computer are in good shape and connected solidly with no issue to the connectors. If all that seems fine, I would probably disconnect the wiper motor for awhile and see if the issue still occurs. I'd probably pull the connectors between the wiper module and computer taking that connection and harness out of the equation altogether and see if the issue persists.

Basically a process of elimination until you can isolate the source.

Also, I'd skip the dealer or any other general mechanic at this point and find a good auto electric specialist if you can't or don't want to try and track it down yourself.

So when I was reading this earlier I had forgotten all the prior discussion. Just re-read the whole thread. I know you got a "new" TIPM, but it it possible that it was a remanufactured one? I looked at your profile and saw you have a 2007 and there's a recall for the issue of engine stalling under "certain operating conditions" that requires a flash of the TIPM to correct. May or may not be related, but found it interesting.
