Pinpoint Test M: DTC P0A7D

High-Voltage Traction Battery

Pinpoint Test M: DTC P0A7D

Refer to Wiring Diagram Set 12, Charging System for schematic and connector information Electrical Diagrams.

Normal Operation

The Battery Control Module - High Voltage Traction Battery (BCM-HVTB) monitors the High Voltage Traction Battery (HVTB) state of charge when the key is in the ON or OFF position.

- DTC P0A7D (Hybrid Battery Pack State Of Charge Low)- The BCM-HVTB (Battery Control Module - High Voltage Traction Battery) sets this DTC only when the ignition switch is first turned to the ON position, or when the ignition switch is in the START position. This condition may occur if the vehicle has been stored for an extended period of time.

This pinpoint test is intended to diagnose the following:

- HVTB (High Voltage Traction Battery)

- Vehicle condition:
- If it has been stored for an extended period of time

- Excessive engine start attempts

- Engine operation for an extended period of time

M2 CHECK FOR CORRECT BCM-HVTB (Battery Control Module - High Voltage Traction Battery) OPERATION

NOTE: This pinpoint test step only addresses the 40-pin connector for the BCM-HVTB (Battery Control Module - High Voltage Traction Battery). It is not necessary to disconnect the high-voltage connectors when following this pinpoint test step procedure.

- Disconnect: BCM-HVTB (Battery Control Module - High Voltage Traction Battery) C4227A.

- Check for:
- corrosion.

- pushed-out pins.


- Connect BCM-HVTB (Battery Control Module - High Voltage Traction Battery) C4227A and make sure it seats correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new HVTB (High Voltage Traction Battery). REFER to High-Voltage Traction Battery . TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
