Code B3794:61 Description
The B3794:61 diagnostic trouble code (DTC) relates to the Cruise Control Function Request Circuit in the vehicle. This code indicates that there is a malfunction in the circuit responsible for sending signals from the cruise control system to the engine control module (ECM) or powertrain control module (PCM). The cruise control system allows the driver to set and maintain a desired speed without having to constantly press the accelerator pedal.
Common Causes of B3794:61
- Faulty cruise control switch: A defective cruise control switch can prevent the system from sending the proper signals to the ECM/PCM.
- Wiring issues: Damaged or corroded wiring in the cruise control circuit can disrupt the signal transmission.
- ECM/PCM failure: A malfunction in the engine control module or powertrain control module can prevent the cruise control system from operating correctly.
- Sensor malfunction: Issues with the vehicle speed sensor or other related sensors can also trigger this code.
- Loose connections: Loose or poor connections in the cruise control circuit can lead to intermittent issues with the system.
Symptoms of B3794:61
- Inoperative cruise control system: The most obvious symptom of this code is that the cruise control system may not engage or maintain the set speed.
- Cruise control light flashing: The cruise control light on the dashboard may flash or remain illuminated, indicating a problem with the system.
- Engine hesitation: A malfunction in the cruise control circuit can sometimes cause the engine to hesitate or surge unexpectedly.
- Check Engine Light: The Check Engine Light may illuminate on the dashboard along with the B3794:61 code stored in the vehicle's computer.
How to Fix B3794:61
- Diagnostic scan: Begin by using a diagnostic scanner to retrieve the B3794:61 code and identify the specific cause of the issue.
- Check cruise control switch: Inspect the cruise control switch for any signs of damage or wear. Replace if necessary.
- Check wiring and connections: Thoroughly examine the wiring harness and connectors in the cruise control circuit for any damage or corrosion. Repair or replace as needed.
- Test sensors: Test the vehicle speed sensor and other related sensors to ensure they are functioning correctly.
- ECM/PCM inspection: If all other components check out, consider having the engine control module or powertrain control module inspected for any faults.
Cost to Fix B3794:61
The cost of repairing the Cruise Control Function Request Circuit issue can vary depending on the specific cause of the problem and the labor rates in your area. On average, you can expect to pay anywhere from $100 to $300 for parts and labor.
