Circuit/System Verification

WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. 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 air bag
    • Inflatable restraint sensing and diagnostic module
    • All wiring harness connectors
    • Inflatable restraint sensing and 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.
    NOTE:

    For connector location and identification refer to Master Electrical Component List .

  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.
    • F106D Seat Side Air Bag - Driver
    • F106DA Seat Side Air Bag - Driver Inboard
    • F106P Seat Side Air Bag - Passenger
    • Any inline harness connector
    • K36 Inflatable Restraint Sensing and 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.
    • Apply dielectric grease/lubricant (Nyogel 760G or equivalent, meeting GM specification 9986087) to each connector terminal.
    • Ensure each connector and CPA is correctly seated.
    • If between 2.1-4.0 Ω without any spikes or dropouts 
  2. All OK
