Measure the resistance of the Driver Squib 2 Line 1 circuit between
ground and the Clockspring connector.

Measure the resistance of the Driver Squib 2 Line 2 circuit between
ground and the Clockspring connector.

Is the resistance below 10K ohms for either measurement?

Yes

>> Repair the Driver Squib 2 circuits with a resistance below

be disconnected.

Repair

Replace the ORC in accordance with the Service Information.

Perform ORC VERIFICATION TEST - VER 1

STORED ORC DTC

With the scan tool, record and erase all DTC’s from all Airbag System Modules.

If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two min-
utes before proceeding.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.

Look for chaffed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or
contaminated terminals.

The following additional checks may assist you in identifying a possible intermittent problem.

Reconnect any disconnected components and harness connector.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.
With the scan tool monitor active codes as you work through the following steps.

Wiggle the wiring harness and connectors of the related airbag circuit or component.

If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.

If only stored codes return continue the test until the problem area has been isolated.

In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.

Are any ACTIVE DTCs present?

Yes

>> Select the appropriate diagnostic procedure from the Table of Contents in this section.

>> No problem found at this time. Erase all codes before returning vehicle to customer.
