DTC U1101: F-CAN Malfunction (Powertrain Control Module (PCM)-Active Control Engine Mount (ACM)): 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 powertrain control module (PCM) does not receive the signals from the engine mount control unit via the F-CAN lines for a set time, the PCM detects a malfunction and stores a DTC.
