Hello folks,
Need help troubleshooting hybrid system on the 2.0 etorque system. Jeep is out of warranty.
The hybrid system is not working at all. Error code that I am getting is Lost communication with the power hybrid module. I thought it was the MGU (alternator) first which includes the hybrid power module so with help of a mechanic friend (who is not familiar with this system) i quickly replaced it but that was not the problem; unless i have to reset something.
Not sure what exactly is happening here but one thing i am noticing is that the 12volt battery is not being charged. I did measure the volts at the MGU (alternator) and with the engine started it was showing 4V (at the red connection on it); i am thinking this should be much higher. I did take the jeep for a test drive and it stalled on me in the shopping center parking allot and would not start even with jumper cables (kept saying the shift the gear in "P" even after disconnecting the battery). So i took the 12 battery home and charged it and put in back in the jeep and it started right up. Really weird?
Why is the 12V battery not being charged with the new MGU? Could it be the 48V battery pack, 12V battery, fuses etc... ?
Any ideas what to look for?
