DTC U0100 (102): F-CAN Malfunction (Powertrain Control Module (PCM)(CVT System)-Motor Control Module (MCM)): 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 for a specified time continuously or when the information sent from the PCM is abnormal and this condition continues for a specified cycle, the motor control module (MCM) detects a malfunction of the F-CAN and when at least one of the other nodes is not malfunctioning after the time to detect BUS-OFF of the F-CAN has passed, a DTC is stored.
