Circuit/System Testing

WARNING: This page is about a different car, the 2010 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: When removing the connectors inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected:
  • PPS module
  • SDM
  • PPS module wiring harness connector
  • SDM wiring harness connector
  1. With a scan tool verify the BCM is programmed with the correct VIN.
  2. Ignition OFF, disconnect the harness connectors at the SDM. Verify the connector is not damaged and has no bent or damaged pins, terminals or shorting bars.
    • If damage is found, repair as necessary and perform the Setup New SDM procedure.
  3. Connect the harness connector at the SDM.
  4. Ignition ON, verify the scan tool system configuration matches the components installed on the vehicle.
    • If the system configuration is not correct, reprogram the SDM with the correct components.
  5. Ignition ON, clear all Passenger Presence System (PPS) and SDM DTCs.
  6. Verify DTC B1019 does not set.
    • If DTC sets, replace the SDM.
