Circuit/System Testing

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect for DTCs P0A40, P0A45, P0A46, P0A78, P0A79, P0A3F, P0C05, P0C08, P0C0B, P0C0E, P0C4E, P0C4F, P0C52, P0C53, P0C57, P0C58, P0C61, P0C62, P0C5C, P0C5D, P1B03, P1B04 or P1B0D.
    • If any of the above DTCs are set, diagnose and repair them prior to performing this diagnostic.
  2. Ignition ON, engine OFF. Observe the BECM Hybrid Battery Pack Calculated parameter. The hybrid battery voltage should be greater than 192V.
    • If the hybrid battery voltage is less than 192V, replace the drive motor generator battery.
  3. Turn the ignition OFF and wait 2 minutes.
  4. Ignition ON, monitor DTC Status. DTC P1B10 and P1B0F should have passed last test.
    • If DTC P0C4E or P0C4F sets, proceed to that diagnostic procedure.
    • If DTC P1B10 and P1B0F have passed, clear DTC Information. No further diagnosis is necessary.
    • If DTC P1B10 or P1B0F resets, program the PIM with the latest software version and recheck for DTCs. If the DTC resets after programming or if the PIM already contains the latest software version, replace the applicable drive motor generator stator assembly.
