Cruise Control System Active Indicator Circuit

Diagnostic Fault Information






Circuit/System Description

The cruise control switch contains an LED that illuminates to indicate the cruise control system has been switched ON. Voltage is applied through the ON/OFF switch to the LED when the switch is pressed. The body control module (BCM) provides the ground path for the LED through a dedicated LED control circuit. Pressing the switch again opens the switch and the lamp turns OFF.

Conditions for Running the DTC

* The ignition is ON.

* The cruise switch is ON.

Conditions for Setting the DTC

* The BCM detects excessive current in the cruise control indicator signal circuit.

* The above condition is present for greater than 5 seconds.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the steering wheel controls switch - left.

2. Ignition ON, verify that a test lamp illuminates between the signal circuit terminal 9 and B+.

• If the test lamp does not illuminate, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.

3. If all circuits test normal, test or replace the steering wheel controls switch - left.
