DTC Descriptor

DTC B0835 00
- 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 BCM provides the ground path for the LED through a dedicated dimming control circuit. Pressing the switch again opens the switch and the lamp turns OFF.

Conditions for Running the DTC

The ignition is ON.

Conditions for Setting the DTC

* The BCM detects excessive current in the cruise control indicator dimming signal circuit.
* The above condition is present for greater than 5 seconds.

Action Taken When the DTC Sets

* The BCM stores DTC B0835 in memory.
* The cruise control system becomes inoperative.

Conditions for Clearing the DTC

* The DTC becomes history when the conditions for setting the DTC are no longer present.
* The history DTC clears after 50 malfunction-free warm-up cycles.


Circuit/System Verification

Ignition ON, observe the cruise control indicator while applying the cruise On/Off switch. The indicator should turn on and off accordingly with the applied switch.

Circuit/System Testing

Caution: Refer to Restraint System Service Precautions.

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.
2. Disconnect the harness connector at the cruise control switch assembly.
3. Ignition ON, test for 0 volts between the cruise control harness connector terminal 9 and ground.

^ If voltage is present, test the circuit for a short to voltage.

4. If the circuit tests normal, replace the BCM.
