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 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.

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

Actions Taken When the DTC Sets

* The malfunction indicator lamp (MIL) will not illuminate.
* The cruise control system is disabled.

Conditions for Clearing the DTC

* The condition responsible for setting the DTC no longer exists.
* A history DTC will clear after 40 malfunction-free ignition cycles have occurred.

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

Important: Refer to DTC B3794 (B3794) before performing this diagnostic, if this code is set as current or history.


1. Ignition OFF, disconnect the harness connector at the steering wheel control switch-left.
2. Ignition ON, verify that a test lamp illuminates between the low reference circuit terminal 9 (Chevrolet) or 6 (Pontiac) and B+.

• If the test lamp does not illuminate, test the low reference 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.

Repair Instructions

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