Vehicle odometer information is sent to the instrument cluster from the anti-lock brake system/traction control (ABS/TC) module or ABS module over the standard corporate protocol (SCP) communication network, circuits 4-EG8 (GY/VT) and 5-EG8 (BU/WH). Instrument cluster DTC U1123 will be logged if the instrument cluster fails to receive the odometer rolling count status from the ABS/TC module or ABS module. Instrument cluster DTC B2143 will be logged if the instrument cluster detects a non-volatile memory (NVM) failure.

Possible Causes
- ABS/TC module or ABS module
- instrument cluster
