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 before performing this diagnostic, if this code is set as current or history.
- Ignition OFF, disconnect the harness connector at the steering wheel control switch-left.
- Ignition ON, verify that a test lamp illuminates between the low reference circuit terminal 9 (Chevrolet) or 6 (Pontiac) and B+.
- If all circuits test normal, test or replace the steering wheel controls switch-left.
| ⇒ | 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. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
