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 PPS module and the SDM.
  2. Test for less than 1.0 ohm between the serial data circuit terminal 18 at the PPS harness connector and terminal 60 at the SDM harness connector.
    • If greater than the specified range, test the signal circuit for an open/high resistance.
  3. If all circuits test normal, test or replace the PPS module.
