Circuit/System Verification
WARNING: This page is about a different car, the 2010 Cadillac SRX. 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
- Passenger instrument panel air bag
- Seat side air bag
- Roof rail air bag
- SDM
- SDM wiring harness connector
- Roof rail air bag wiring harness connector
- Seat side air bag wiring harness connector
- Passenger instrument panel air bag wiring harness connector
- Seat belt retractor pretensioner 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 Nyogel lubricant 760G. This procedure will correct the high resistance condition due to terminal fretting corrosion.
Observe the scan tool Deployment Loop Resistance parameters while moving the harness near each connector listed below. The reading should stay consistently between 1.7 and 4.2 Ω without any drop outs or spikes.
- F105 Passenger instrument panel air bag, and Roof rail air bag
- F106 Seat side air bag
- F112 Seat belt retractor pretensioner
- Any inline harness
- K36 SDM
- If the reading is erratic while moving the harness, perform the following:
- Inspect each connector terminal for damage or corrosion and repair as necessary.
- Apply Nyogel lubricant 760G to each connector terminal.
- Insure each connector and CPA is correctly seated.
