Circuit/System Testing

WARNING: This page is about a different car, the 2013 GMC Acadia, 2013 Chevrolet Traverse, and 2013 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

The passenger presence system (PPS) is a calibrated unit. When replacing the assembly all parts in the service kit must remain together. Do not mix any of the old parts with the new parts. PPS comes in as part of a service kit which contains a seat foam, presence sensor and a electronic control unit (ECU) module (if applicable).

When removing connectors, inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector:

  • Passenger presence module
  • Passenger presence sensor wiring harness
  1. Verify that no other passenger presence module DTCs are set.
    • If other passenger presence module DTCs are set, investigate those DTCs first.
  2. Verify that DTC B0074 0F is not set.
    • If this DTC is set, verify there are no electronic devices on the passenger seat. If not, then verify the seat is dry by removing the trim from the seat bottom frame. IF the seat is wet, allow 24-48 hours dry time with trim completely off. If the DTC is history, do not replace the passenger presence module. Clear the passenger presence module codes.
  3. Verify that DTC B0074 00, B0074 0D or B0074 0E is not set.
    • If any of the DTCs are set then replace the passenger presence module.
