Circuit/System Testing

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.
    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
    • SDM module
    • PPS wiring harness connector
    • SDM wiring harness connector
  1. Ignition OFF, disconnect the harness connector at the inflatable restraint front PPS sensor.
  2. Ignition OFF, test for less than 1.0 ohm between the low reference circuit terminal C and ground.
    • If not within the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the PPS.
  3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal A and ground.
    • If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the PPS module.
    • If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the PPS module.
  4. Ignition OFF, disconnect the harness connector at the PPS module.
  5. Ignition OFF, test for infinite resistance between the signal circuit terminal B and ground.
    • If not the specified value, test the signal circuit for a short to ground.
  6. Ignition ON, test for less than 1.0 volt between the signal circuit terminal B and ground.
    • If not within the specified range, test the signal circuit for a short to voltage.
  7. Test for less than 1.0 ohm between the signal circuit terminal B at the sensor harness connector and terminal 6 at the PPS harness connector.
    • If greater than the specified range, test the signal circuit for an open/high resistance.
  8. If all circuits test normal, test or replace the inflatable restraint PPS sensor.
