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:
  • Refer to SIR Service Precautions .
  • Inspect all terminals for damage or corrosion when disconnecting connectors. Damage or corrosion in the following requires repair or replacement of the affected component/connector.
    • Seat belt retractor pretensioner
    • Inflatable restraint and sensing diagnostic module
    • Seat belt retractor pretensioner wiring harness connector
    • Passenger instrument panel air bag wiring harness connector
    • Seat side air bag wiring harness connector
    • Roof rail air bag wiring harness connector
    • Inflatable Restraint and Sensing Diagnostic Module wiring 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. The CPA isolates the shorting-bars within the connector allowing the deployment circuit to operate properly.
  • If the condition is intermittent or cannot be duplicated, disconnect the connectors and add dielectric grease / lubricant (Nyogel 760G or equivalent, meeting GM specification 9986087). This procedure will correct the high resistance condition due to terminal fretting corrosion.
  1. Verify the appropriate scan tool Deployment Loop Resistance parameters stay consistently between 2.1-4.0 Ω without any spikes or dropouts while moving the harness near each connector listed below:
    • F112 Seat Belt Retractor Pretensioner
    • F113 Seat Belt Anchor Pretensioner
    • Any inline harness connector
    • K36 Inflatable Restraint and Sensing Diagnostic Module
    • If less than 2.1 Ω or greater than 4.0 Ω 

      Refer to Circuit/System Testing.

    • If there are spikes or dropouts, perform the following 
    • Inspect each connector terminal and harness for damage or corrosion and repair as necessary
    • Ensure each connector and CPA is correctly seated.
    • If between 2.1-4.0 Ω without any spikes or dropouts 
  2. All OK
