Pinpoint Test M: DTC P0ABD:00

High-Voltage Traction Battery

Pinpoint Test M: DTC P0ABD:00

Refer to Wiring Diagram Set 12, Charging System for schematic and connector information. [1][2]Diagrams By Number

Normal Operation

The Battery Pack Sensor Module (BPSM) monitors battery pack voltage using voltage sensors within the High Voltage Traction Battery (HVTB). The BPSM (Battery Pack Sensor Module) communicates normal pack voltage which should be between 179-343 volts.

- P0ABD:00 (Hybrid Battery Pack Voltage Sense A Circuit High: No Sub Type Information)- Fault is set when BPSM (Battery Pack Sensor Module) senses voltage greater than 350 volts.

This pinpoint test is intended to diagnose the following:

- BPSM (Battery Pack Sensor Module)

- HVTB (High Voltage Traction Battery)

PINPOINT TEST M : DTC P0ABD:00

WARNING: To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to depower the system. The high-voltage hybrid system utilizes approximately 300 volts DC, provided through high-voltage cables to its components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious personal injury or death.

WARNING: Always inspect gloves before each use to prevent high-voltage shock. High-voltage insulated safety gloves with a leather outer glove are required to service some components of this vehicle where specified in the service procedures. All high-voltage insulated safety gloves must meet or exceed ANSI/ASTM class 00. Refer to Rubber Insulating Gloves Testing . Failure to follow these instructions may result in serious personal injury or death.

M1 RETRIEVE ALL BECM (Battery Energy Control Module) DTCs

- Connect the scan tool.

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: Self Test- BECM (Battery Energy Control Module).

Do any DTCs other than P0ABD:00 exist?

Yes
REFER to the Battery Energy Control Module (BECM) DTC Chart and diagnose all other DTCs first. Battery Energy Control Module (BECM) DTC Chart

No
GO to M2.

M2 INSTALL A NEW BPSM (Battery Pack Sensor Module)

WARNING: Always wear high-voltage insulated safety gloves with leather outer gloves and a face shield when servicing the battery pack sensor module (BPSM) and never remove the high-voltage BPSM connector unless directed by a service procedure. High voltage is present at the BPSM at all times, even with service disconnect plug removal. Depowering the system will not remove voltage from the BPSM connector with the orange harness. Follow all service instructions. Failure to follow these instructions may result in serious personal injury or death.

WARNING: Never install the service disconnect plug with the high-voltage bussed electrical center (BEC) cover removed. Always install the cover prior to connecting the service disconnect plug. The high-voltage BEC cover prevents inadvertent contact with the high voltage which is present at several points under the cover. Failure to follow these instructions may result in serious personal injury or death.

- Ignition OFF.

- Depower the HVTB (High Voltage Traction Battery) system. Refer to High-Voltage Traction Battery Systems Depowering .

- Install a new BPSM (Battery Pack Sensor Module). Refer to Battery Pack Sensor Module (BPSM) .

- Connect: Service Disconnect Plug.

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: Clear DTCs- BECM (Battery Energy Control Module).

- Enter the following diagnostic mode on the scan tool: Self Test- BECM (Battery Energy Control Module).

Is DTC P0ABD:00 retrieved?

Yes
INSTALL a new HVTB (High Voltage Traction Battery) (includes HVTB (High Voltage Traction Battery) system wire harness). REFER to High-Voltage Traction Battery . CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.

No
The repair is now complete. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
