Code P1D02 Description

The motor control processor is in the motor control module. The controller area network (CAN) transmits/receives pulsing signals to/from the control modules simultaneously by using two signal lines (F-CAN A_H and F-CAN A_L) and (EPP-CAN_H and EPP-CAN_L). The F-CAN and the EPP-CAN sends same data. If the F-CAN or the EPP-CAN does not transmit/receive data, the normal signal line can transmit/receive data. If the F-CAN and the EPP-CAN does not transmit/receive data, the motor control module cannot run normally. The motor control module detects no signal, received data is abnormal or BUS-OFF is received via the F-CAN and EPP-CAN, the motor control module detects a malfunction and stores a DTC.
