Code P1D03 Acura Description

The battery control processor is in the battery condition monitor 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 battery condition monitor module cannot run normally. The battery condition monitor module detects no signal, received data is abnormal or BUS-OFF is received via the F-CAN and EPP-CAN, the battery condition monitor module detects a malfunction and stores a DTC.
