Circuit/System Verification

NOTE:

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
Knee air bag
Seat air bag
Roof rail air bag
SDM
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
SDM wiring harness connector

NOTE:

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.

Verify the scan tool Deployment Loop Resistance parameters stay consistently between 2.1 and 4.0Ω without any spikes or dropouts while moving the harness near each connector listed below:
- F105 Passenger instrument panel air bag
- Any inline harness connector
- K36 SDM
- If less than 2.1 or greater than 4.0Ω
  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
- Insure each connector and CPA is correctly seated.
- If within 2.1 and 4.0Ω without any spikes or dropouts
All OK
