Circuit/System Testing
WARNING: This page is about a different car, the 2012 Chevrolet Volt. However, it is still accessible from the selected car via links, so may be relevant.
- Verify that DTC P0A45, P0A46, P0C57, P0C58, P0C61, P0C62, or P1B04 are not set.
- If any of the DTCs are set, refer to DTC P0A45, P0A46, P0C57, P0C58, P0C61, P0C62, or P1B04 .
- Vehicle OFF, disconnect the X1 and X2 harness connectors at the transmission.
- Disconnect the X1 harness connector at the T6 power inverter module.
- Test for less than 1 Ω between the terminals listed below:
- Terminals 20 and X1 terminal 1
- Terminals 30 and X1 terminal 2
- Terminals 21 and X1 terminal 3
- Terminals 31 and X1 terminal 4
- Terminals 22 and X2 terminal 1
- Terminals 32 and X2 terminal 1
- If greater that the specified range, test the signal circuit for an open/high resistance.
- If all circuits test normal, replace the drive motor generator 2 position sensor.
NOTE:
You must perform the Component Testing before proceeding with Circuit/System Testing.
