DTC U0029 (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). If the bus-off condition continues for a prescribed time, the motor control module in the power control unit (PCU) detects a malfunction and stores a DTC.
