Circuit/System Verification

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

This system allows you to service each component separately (module and sensor/sensing mat). Perform a Passenger Presence System Rezeroing

Passenger presence sensor
Passenger presence sensor harness connector
Passenger presence module
Passenger presence module harness connector
Seat wiring harness to vehicle harness connector

The connector and connector position assurance (CPA) may seat independent of each other. Both the connector and CPA should seat with an audible and/or tactile click.

Observe with the scan tool if the fault changes status while moving the passenger seat forward and backward through its full range of motion. The status should stay consistent.
- The status changes
  If the status changes this could be indication of a seat to vehicle harness connection issue, refer to Circuit/System Testing.
- The status does not change
Observe with the scan tool if the fault changes status while moving the harness near each connector listed below. The status should stay consistent.
- Passenger presence module
- Passenger presence sensor
- Any seat harness inline
  - The status changes
    If the reading is erratic while moving the harness, perform the following:
- Inspect each connector terminal for damage or corrosion and repair as necessary.
- Insure each connector and CPA is correctly seated.
  - The status does not change
All OK.
