Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Ok, can I get the 17 digit vin number to ensure accuracy of answer
By the vin number, I am not showing a BCM, but rather the functions of the BCM handled by the instrument cluster, rke module, compass module, airbag module
Is there a specific fault code? A communication code should be Uxxxx - example U0110
Sorry for the delay. Having some internet issues
SYMPTOM U110C-NO FUEL LEVEL BUS MESSAGE WHEN MONITORED Ignition on. SET CONDITION No fuel level BUS messages received by the PCM for 20 seconds. POSSIBLE CAUSES - Communicate with cluster - Fuel level bus message - PCI bus circuit open from PCM to instrument cluster - Instrument cluster
You need to check the harness connectors to the instrument cluster, including loose or chafed wire and repair as needed. If ok, the instrument cluster should be replaced and programmed
The BUS line goes directly from the cluster to the PCM

did you ever have the P0300, P0032 or P0038 before replacing the cluster?
The P0300 is random misfire and the P0032 and P0038 are O2 sensors.
The U0155 is no cluster bus message
Ok, let me pull all the schematics and go thru them. Give me about an hour or so on them
I have gone thru all my schematics, checked for any service bulletins I may have overlooked and everything I see points to the instrument cluster, but unless the new one is simply defective out of the box, there is another issue but I am not seeing it
Possible, as there are a few wiring circuits between the ignition switch and the instrument cluster as well as the radio.
you would need to remove the trim panel around the audio unit and make it so you could access the harness connectors to it easily and when the audio unit loses power, check the large red with white striped wire for power. If no power, that would indicate the ignition switch as that is what feeds this wire
