Diagnostic Test
1.
DTC STATUS IS ACTIVE
Turn the ignition on.
With the scan tool, select View DTCs in the Steering Column Module.
Is the DTC status Active at this time?
Yes
>> Go to 2
No
>> Go to 5
2.
(G20) IGNITION SWITCH SENSE CIRCUIT SHORT TO GROUND
Turn the ignition off.
Disconnect the Steering Column Module harness connector.
Measure the resistance between ground and the (G20) Ignition Switch
Sense circuit in the Steering Column Module harness connector.
Is the resistance below 5.0 ohms?
Yes
>> Repair the (G20) Ignition Switch Sense circuit for a short
to ground.
No
