DTC Descriptor
DTC B0835: Cruise Control System Active Indicator CircuitDiagnostic Fault Information
Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
Cruise Control Indicator Dimming Control | -- | -- | B0835 | -- |
Cruise Control Switch Signal | B3794 | B3794 | B0835 | B3794 |
Circuit/System Description
The body control module (BCM) monitors the cruise control indicator dimming control switch and the cruise control switch signal circuits. When the cruise on/off switch is pressed ON, the steering wheel control switch assembly - left is closed and the signal circuits are high. When the cruise on/off switch is pressed OFF, the cruise control switch is open and the signal circuit are 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 control or the cruise control switch 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. |
Diagnostic Aids
Using the Failure Records data may help locate an intermittent condition. If you cannot duplicate the DTC, the information in the Failure Records can help determine how many miles since the DTC set. The Fail Counter and Pass Counter can help determine how many ignition cycles that the diagnostic test reported a pass and/or a fail.

Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the steering wheel control switch assembly - left.
- Ignition ON, verify that a test lamp does not illuminate between the cruise control indicator dimming control circuit terminal 9 and ground.
- Ignition ON, verify a test lamp does not illuminate between the cruise control switch signal circuit terminal 3 and ground.
- If all circuits test normal, replace the steering wheel control switch assembly - left.
| ⇒ | If the test lamp illuminates, test the cruise control indicator dimming control circuit for a short to voltage. If the circuit tests normal, replace the BCM. |
| ⇒ | If the test lamp illuminates, test the cruise control switch signal circuit for a short to voltage. If the circuit tests normal, replace the BCM. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
