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 (F-CAN H and F-CAN L). 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.
