WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected.
- PPS module
- PPS module wiring harness
- Ignition OFF, disconnect the harness connectors at the Passenger Presence System.NOTE: Some control module ground circuits may require up to 20 minutes after the ignition is turned off before achieving a resistance reading of less than 5 ohms. In most cases the readings will drop below 20 ohms within 1 minute indicating the control module is going to sleep.
- Ignition OFF, scan tool disconnected, open and close the driver door and wait 1 minute. Test for less than 5 ohms between the ground circuit terminal 3 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition OFF, verify that a test lamp illuminates between the ignition circuit terminal 2 and ground.
- If test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
- If all circuits test normal, reconnect harness and confirm that DTCs are history, if history clear DTCs.
- If DTC is still current, replace the PPS module.
