DTC U0146 (Motor Control Module): 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 (H line and L line). When the motor control module in the power control unit (PCU) does not receive the signals from the CAN gateway via the F-CAN lines or the received data is abnormal for a specified time, a malfunction is detected and a DTC is stored.
