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.

Scan Tool Data List

1. Ignition OFF, disconnect the cruise control switch assembly.
2. Connect a fused jumper between the voltage signal circuit and the low reference circuit.
3. Ignition ON, observe the Cruise On/Off Switch parameter.

⇒	If the Cruise On/Off Switch parameter displays ON, replace the cruise control switch assembly.

⇒	If the Cruise On/Off Switch parameter displays Off, test the voltage signal circuit and the low reference circuit for an open/high resistance.

4. If all circuits test normal, replace the BCM.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
