Cruise Control Switch Indicator Inoperative

Cruise Control Switch Indicator Inoperative

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview
* Review Strategy Based Diagnosis for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions provides an overview of each diagnostic category.

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.

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

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure. Verification Tests

* Steering Wheel Control Switch Assembly Replacement
* Programming and Relearning for setup, and programming. Programming and Relearning
