DTC U0100 (103): F-CAN Malfunction (Powertrain Control Module (PCM)(CVT System)-Battery Condition Monitor (BCM) Module): General 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 powertrain control module (PCM) through the F-CAN and this condition continues for a specified time or when the information sent from the PCM 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.
