I don't know is a right thread to ask.
I have Wrangler in my workshop, customer want to change the halogen headlamp (H4) to LED headlamp.
I could see in BCM the coding value's and it has option to coding Bi-Xenon type.
First question: Somebody said the AlfaOBD S/W is able to do it, is it true?
Second question: It will work this setup?
Now the head lamp working about 40 second and goes off.
I did try few tricks but nothing work so far.

Thank you.]]>

This USA specifications Jeep Grand Cherokee 2012 5.7L V8 car has a front accident that touched the ECM.
After that the car was starting but was behaving erratically and after sometime did not start anymore (as the owner says).
The other technician swapped ECM and the engine starts but the gearbox is not active.
What do I have to do to solve this problem?
Probably there is something to do like synchronize the new (its an already used one) ECM with the other ECU in the car or with the gearbox?
What tools do I need for that?
Is the tool WiTECH MicroPod 2 Diagnostic Tool V17.04.27 For Fiat Dodge Jeep Chrysler suitable for the job?
Or do I have to go with Abrites AVDI or other tool (thanks for sharing the name of it)?

Please help.]]>

We have this vehicle which is driving us crazy.

VIN: 1C4RJFFM7CC227996

It had a non start issue as in if you swing the key to start position nothing happens. This vehicle has the proximity feature as well.
We run a diagnostic and we received a fault code on the WCM/Wireless Control Module of an internal fault.

[attachment=39912]

I ordered a new unit, sent the vehicle to the dealership for programming.
The dealership then calls me and says that they have programmed the new WCM but they also needed to program a new Electronic Steering Lock at the same time so now the new WCM I bought is wasted. I am not sure if this is true or not? The dealership wants me to buy another WCM and ESL + programming + labour to have the car fixed. These are the fault codes after I took the car back from them.

[attachment=39911]

The customer has refused to pay any more and wants me to refund his money.
Please advice me on what to do...]]>

Removed the generator and try it with an external regulator on test bench, but the electrical motor in test bench can not drive, because generator charge much ampere.

Regulator has one cable on it, when i measure with oscilloscope this cable without generator and initiation on there is a pwm signal.

This car comes not shifting to drive.
Sometime stuck at P but when you wait for a while will shift to N and stuck won’t shift to drive and won’t shift back to P, till you wait a while.

DTC's are:
P0610-00 ECU Vehicle option mismatch - Active
P1500-00 ECU Configuration mismatch

This is the only fault in the TCM.
If I perform ECU reflash with PassThru device through tech-authority without Micropod would it cure this two fault codes.
Maybe could be the reason why shifter not shifting well. And reverse shudder.]]>

Jeep Grand Cherokee overland 2012.
VIN: 1C4RJFGG7CC202122
Euro Spec
Right Hand Drive

This vehicle was towed in to the shop As a non starter
History:
Alternator was not charging so battery went flat. A new alternator and new battery installed since then the vehicle does not start.
Alternator and battery not installed buy us.
Diagnosis session:
I can connect to all control units using Launch X431, the starter does not swing. In the ECM there is one fault code which I cannot erase.
P0688-Auto Shutdown relay sense circuit low
I have checked and load tested ASD relay control wire from ECU to the ASD relay. I can activate the relay from the ECU with the power probe.
I have checked for good power at the ASD relay... All OK
I am about to quote for a new ECU. It is a big ticket item in my part of the world so I need to be 100% sure.

Any advice welcome.]]>

I have a Jeep Grand Cherokee 1999 V6 engine in line, and I have a problem that's is very weird, when you are driving (engine cool or hot) and you reach around 60 km or sometimes even less, the engine start loosing power, and when you try to accelerate you can hear explosions and won't accelerate, so what I do is to slowly start to accelerate to continue.

I already scan the truck with DRB III and there is no data or DTC present, the light is off , or any trace of a DTC in other modules.
Already change the ECM for a new one , gasoline pump and everything related to the gas.

Any ideas or related problem with this ?
