P0ADE

High-Voltage Traction Battery

Pinpoint Test R: DTC P0ADA:00 or P0ADE:00

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

Normal Operation

When the ignition is turned on, the Battery Energy Control Module (BECM) makes various vehicle checks. If these checks are normal, the BECM (Battery Energy Control Module) sends a signal to the contactor to close which will supply power to the high-voltage vehicle systems. The Battery Pack Sensor Module (BPSM) monitors the battery voltage from inside the High Voltage Traction Battery (HVTB) and the high-voltage Bussed Electrical Center (BEC). The powertrain malfunction (wrench) warning indicator will be illuminated when a fault is present.

- P0ADA:00 (Hybrid Battery Positive Contactor Control Circuit Range/Performance: No Sub Type Information)- This DTC will set if positive contactor voltage is below or above 179-343 volts for 1 second or more.

- P0ADE:00 (Hybrid Battery Negative Contactor Control Circuit Range/Performance: No Sub Type Information)- This DTC will set if voltage at the negative contactor is below or above 179-343 volts for 1 second or more.

This pinpoint test is intended to diagnose the following:

- BPSM (Battery Pack Sensor Module)

- High-voltage BEC (Bussed Electrical Center)

- HVTB (High Voltage Traction Battery)

PINPOINT TEST R : DTC P0ADA:00 OR P0ADE: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.

R1 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 P0ADA:00 or P0ADE: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 R2.

R2 INSTALL A NEW HIGH-VOLTAGE BEC (Bussed Electrical Center)

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 high-voltage BEC (Bussed Electrical Center). Refer to High-Voltage Bussed Electrical Center .

- 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).

Did DTC P0ADA:00 or P0ADE:00 return?

Yes
GO to R3.

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

R3 INSTALL A NEW BPSM (Battery Pack Sensor Module)

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.

- Using the scan tool, clear any BECM (Battery Energy Control Module) DTCs.

- 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).

Did DTC P0ADA:00 or P0ADE:00 return?

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.
