* 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

Refer to SIR Service Precautions (See: Restraints and Safety Systems/Air Bag Systems/Service Precautions/Technician Safety Information).

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 anchor pretensioner

* SDM

* Seat belt anchor pretensioner 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. Replace

any CPA that is damaged or missing.

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.

1. Ignition OFF, disconnect the harness connector at the appropriate F113 seat belt anchor pretensioner.

2. Disconnect the scan tool.

3. Wait for 120 seconds and then test for greater than 25 ohm between the seat belt anchor pretensioner control circuits terminal 1 and terminal

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.

4. Ignition ON, test for less than 11 V between each of the seat belt anchor pretensioner control circuit terminals 1 and 2 and ground.

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.

5. Ignition OFF, test for greater than 25 ohm between each of the seat belt anchor pretensioner control circuit terminals 1 and 2 and ground.

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.

6. Install a 3 A fused jumper wire between the seat belt anchor pretensioner control circuits terminal 1 and terminal 2.

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

瀚慖f greater than the specified range, test the control circuit terminals 1 and 2 for an open/high resistance. If the circuits test normal, replace

the K36 SDM.

8. If all circuits test normal, replace the F113 seat belt anchor pretensioner.
