Cruise Control Switch Indicator Inoperative

CRUISE CONTROL SWITCH INDICATOR INOPERATIVE

DIAGNOSTIC FAULT INFORMATION
Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview

CIRCUIT/SYSTEM DESCRIPTION
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.

CIRCUIT/SYSTEM TESTING
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, or for a high resistance.
- If all circuits test normal, replace the BCM.

REPAIR INSTRUCTIONS
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
- Steering Wheel Control Switch Assembly Replacement
- Control Module References for BCM replacement, setup, and programming. Programming and Relearning Verification Tests
