The body control module (BCM) monitors the cruise control indicator switch. When the cruise on/off switch is pressed ON, the cruise control switch is closed and the signal circuit is low. When the cruise on/off switch is pressed OFF, the cruise control switch is open and the signal circuit is high.

Caution: Refer to SIR Caution in the Preface section.

Disable the inflatable restraint steering wheel module when performing this diagnostic. Refer to SIR Disabling and Enabling .

1. Ignition OFF, remove the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement .
2. Disconnect the harness connector at the cruise control switch assembly.
3. Cruise switch ON, test for less than infinite resistance between the steering wheel supply voltage terminal 1 and the cruise control indicator dimming signal terminal 9 on the cruise control switch.

⇒	If the resistance measured is infinite, replace the cruise control switch assembly.

4. Test the cruise control dimming indicator signal circuit for an open/high resistance between the BCM and the cruise control switch assembly.

⇒	If the cruise control dimming indicator signal circuit tests normal, replace the BCM.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
