- 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 ohm 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.

Circuit/System Testing

DTC B0014-B0018 or B0021-B0045

1. Ignition OFF, disconnect the harness connector at the appropriate F105, F106 air bag or F112 seat belt retractor pretensioner.

2. Ignition OFF, disconnect the scan tool, wait 120 seconds, test for greater than 25 ohm between the control circuit terminals listed below:

* F105 Left roof rail airbag terminal 1 and 2

* F105 Right roof rail airbag terminal 1 and 2

* F106 Driver seat side airbag terminal 1 and 2

* F106 Passenger seat side airbag terminal 1 and 2

* F112 Driver seat belt retractor pretensioner terminal 1 and 2

* F112 Passenger seat belt retractor pretensioner terminal 1 and 2

瀚慖f less than the specified range, test for a short between the control circuits, check each connector and CPA to ensure that the shorting

bars are lifted. If the circuits and shorting bars tests normal, replace the K36 SDM.

3. Ignition ON, test for less than 11 V between the control circuit terminals listed below and ground:

* F105 roof rail air bag or F106 seat side air bag control circuit terminal 1

* F105 roof rail air bag or F106 seat side air bag control circuit terminal 2

* F112 seat belt retractor pretensioner control circuit terminal 1

* F112 seat belt retractor pretensioner control circuit terminal 2

瀚慖f greater than the specified range, test the control circuit for a short to voltage. If the circuit tests normal, replace the K36 SDM.

4. Ignition OFF, test for greater than 25 ohm between the control circuit terminals listed below and ground:

* F105 roof rail air bag or F106 seat side air bag control circuit terminal 1

* F105 roof rail air bag or F106 seat side air bag control circuit terminal 2

* F112 seat belt retractor pretensioner control circuit terminal 1

* F112 seat belt retractor pretensioner control circuit terminal 2

瀚慖f less than the specified range, test the control circuit for a short to ground. If the circuit tests normal, replace the K36 SDM.

5. Install a 3 A fused jumper wire between the control circuit terminals listed below:

* F105 Left roof rail air bag terminal 1 and 2

* F105 Right roof rail air bag terminal 1 and 2

* F106 Driver seat side air bag terminal 1 and 2

* F106 Passenger seat side air bag terminal 1 and 2

* F112 Driver seat belt retractor pretensioner terminal 1 and 2

* F112 Passenger seat belt retractor pretensioner terminal 1 and 2

6. Verify the scan tool Deployment Loop Resistance parameter is less than 2 ohm.
