NOTE: 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
  • PPS module harness connector
  • SDM wiring harness connector
  1. Ignition OFF, disconnect the harness connector at the PPS module.
  2. Ignition OFF, test for less then 10 Ω between the ground circuit terminal 4 and ground.
    • If greater then the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify a test lamp illuminates between the B+ circuit terminal 3 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. Reconnect all PPS components and perform the Passenger Presence System Preload Test .
  5. Clear all DTCs and operate the vehicle. DTC B0081 should not set.
    • If DTC B0081 sets, replace the PPS.
