G1: STEERING WHEEL (MODULE AND LIN) OPEN CIRCUIT TEST 1
1. Refer to the relevant article of the workshop service information and remove the driver airbag
2. Check the integrity of the wiring harness (clockspring to steering wheel heater control module)
Is a wiring harness fault present?

Yes : Repair the harness as necessary

No: GO to G2.
G2: STEERING WHEEL (MODULE AND LIN) OPEN CIRCUIT TEST 2
WARNING: Do not probe or disconnect the airbag connector(s) during this test.

NOTE: Rotate the steering wheel during this test to check for an intermittent fault.
1. Disconnect clockspring connector C2R115C
2. Disconnect clockspring connector C2LS41
3. Set a multimeter to measure resistance
4. Connect the multimeter to clockspring connector C2R115C terminal 4 and clockspring connector C2LS41 terminal 7
Does the multimeter display > 0 ohms?

Yes : Install a new clockspring

No: GO to G3.
G3: STEERING WHEEL (MODULE AND LIN) OPEN CIRCUIT TEST 3
WARNING: Do not probe or disconnect the airbag connector(s) during this test.

NOTE: Rotate the steering wheel during this test to check for an intermittent fault.
1. Connect the multimeter to clockspring connector C2R115C terminal 1 and clockspring connector C2LS41 terminal 8
Does the multimeter display > 0 ohms?

Yes : Install a new clockspring

No: GO to G4.
G4: STEERING WHEEL (MODULE AND LIN) OPEN CIRCUIT TEST 4
WARNING: Do not probe or disconnect the airbag connector(s) during this test.

NOTE: Rotate the steering wheel during this test to check for an intermittent fault.
1. Connect the multimeter to clockspring connector C2R115C terminal 2 and clockspring connector C2LS41 terminal 4
