DTC U0100 (Engine Mount Control Unit (Without CAN Gateway)): General Description

Courtesy of HONDA, U.S.A., INC.

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 information is not sent from the powertrain control module (PCM) via the F-CAN lines 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 engine mount control unit detects a malfunction and stores a DTC.
