Circuit/System Verification

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. Observe the scan tool Deployment Loop Resistance parameters. The reading should be between 2.1 and 4.0 ohm.

瀚慖f not within the specified range, refer to Circuit/System Testing.

2. Observe the scan tool Deployment Loop Resistance parameters while moving the harness near each connector listed below. The reading

should stay consistently between 2.1 and 4.0 ohm without any drop outs or spikes.

* F113 Seat belt anchor pretensioner

* Any harness inline

* K36 SDM

瀚慖f 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.
