Diagnostic Instructions

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



DTC Descriptor
DTC B0835 00
- Cruise Control System Active Indicator Circuit




Diagnostic Fault Information






Circuit/System Description

The body control module (BCM) monitors the cruise control indicator switch. When the cruise on/off switch is switched ON, the cruise control switch is closed and the cruise indicator signal circuit is high. When the cruise on/off switch is pressed OFF, the cruise control switch is open and the cruise indicator signal circuit is low.


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

1. Ignition OFF, cruise control switch OFF, disconnect the harness connector X3 at the BCM.
2. Ignition ON, verify that a test lamp does not illuminate between the cruise control indicator dimming signal circuit terminal 22 and ground.

• If the test lamp illuminates, test the cruise control indicator dimming signal circuit for a short to voltage. If the circuit tests normal, replace the steering wheel controls switch - left.

3. If the circuits test normal, replace the BCM.



Repair Instructions

Perform theDiagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
