Circuit/System Verification

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.
WARNING: To help avoid personal injury, be careful when working in the vicinity of the generator battery disconnect control module. Internal components will still be live, 36V potential, even when the cover has been opened or removed.
  1. Verify the DTC is set current, clear the DTC.
  2. Ignition ON, using the scan tool special function command the generator battery vent fan ON and OFF several times.
    • If the generator battery vent fan operates as commanded and the DTC resets, refer to Circuit/System Testing.
