- Customer states that the vehicle will not start and they are having problems with the locks and windows also. Technician performed testing and found multiple communication errors. Performed system reset and retested, was able to get the vehicle to start but still has major communication errors. Scoped the CAN lines and data suggests the CEM module has an internal connection issue. Recommend sending CEM out for testing and repair. Sent the module out and bench testing passed. Company returned CEM and upon re installation vehicle would not start, technician banged on CEM module and vehicle started. Contacted repair facility and advised them of the problem starting the vehicle, returned the CEM back to them to retest. Test results revealed a non repairable problem with the circuit board. Transferred security and vehicle information into a replacement module and returned to us. Installed replacement CEM, all vehicle communication restored except for and ignition switch fault the resets every time the car is started. Technician replaced the ignition switch unit and fault has not returned.
