Circuit/System Testing

WARNING: This page is about a different car, the 2010 GMC Canyon and 2010 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
    IMPORTANT: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector.
    • PPS module
    • PPS wiring harness connector
  1. Ignition OFF, disconnect the harness connector at the PPS module.
  2. Ignition OFF, test for less than 5 ohms between the ground circuit terminal 5 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the ignition voltage circuit terminal 9 and ground.
    • If the test lamp does not illuminate, test the ignition voltage circuit for a short to ground or an open/high resistance.
  4. Reconnect all components, clear codes and recheck for DTC 024. Refer to Passenger Presence System Flash Code Procedures 
    • If DTC 032 resets, replace the PPS.
  5. If all circuits test normal, test or replace the PPS module.
