U0110 Description

 

The Controller Area Network (CAN) transmits/receives pulsing signals to/from the control modules simultaneously by using two signal lines (CANH and CANL). When the information is not sent from the Motor Control Module (MCM) through the F-CAN and this condition continues for a specified time or when the information sent from the MCM is abnormal and this condition continues for a specified cycle, the Battery Condition Monitor (BCM) module detects a malfunction and when BUS-OFF is not detected after the time to detect BUS-OFF has passed, a DTC is stored.
