Circuit/System Verification
1. Verify that DTCs P0A95, P0C77, and P1A20 is not set.
锟斤拷If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code
Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle).
2. Verify that DTC P0ABD is not set.
锟斤拷If the DTC is set, replace the drive motor generator battery assembly. If the DTC resets, replace the drive motor generator battery control
module.
3. Ignition ON, engine OFF, observe the scan tool Hybrid Battery Pack Calculated and Hybrid Battery Terminal parameters. The readings
should be between 169 and 408 V and should be within 50 V of each other.
Circuit/System Testing
Danger: Always perform the High Voltage Disabling procedure prior to servicing any High Voltage component or connection. Personal
Protection Equipment (PPE) and proper procedures must be followed.
