The battery control processor is in the battery condition monitor module. The controller area network (CAN) transmits/ receives pulsing signals to/from the battery voltage cell voltage sensor simultaneously by using two signal lines (BATT-CAN_H and BATT-CAN_L). When the processor does not receive the signals via the BAT-CAN lines for a set time, a malfunction is detected and a DTC is stored.
