Code B3794:61 2017 GMC Sierra Description
The B3794:61 diagnostic trouble code (DTC) in a 2017 GMC Sierra relates to the Cruise Control Function Request Circuit. This code indicates that there is a malfunction in the circuit responsible for transmitting signals from the cruise control system to the vehicle's engine control module (ECM). The cruise control system allows the driver to set and maintain a desired speed without having to constantly press the accelerator pedal. When this circuit malfunctions, it can lead to the cruise control system not functioning properly or not engaging at all.
Common Causes of B3794:61 2017 GMC Sierra
- Faulty cruise control switch: A malfunctioning cruise control switch can prevent the signal from reaching the ECM.
- Wiring issues: Damaged or corroded wiring in the cruise control circuit can disrupt the signal transmission.
- ECM malfunction: A faulty ECM may not be able to receive or interpret the signals from the cruise control switch correctly.
- Connector problems: Loose or damaged connectors between the cruise control components can lead to a poor connection and trigger the code.
- Electrical issues: Any electrical problems within the cruise control system, such as a blown fuse, can also cause the code to set.
Symptoms of B3794:61 2017 GMC Sierra
- Inoperative cruise control system: The most obvious symptom of this code is the cruise control system not engaging or working intermittently.
- Cruise control light flashing: The cruise control light on the dashboard may flash or remain illuminated, indicating a problem with the system.
- Speed fluctuations: The vehicle may experience speed fluctuations or difficulty maintaining a constant speed when the cruise control is activated.
- Check Engine Light: The Check Engine Light may illuminate on the dashboard due to the malfunction in the cruise control function request circuit.
How to Fix B3794:61 2017 GMC Sierra
- Diagnose the issue: Use a diagnostic scanner to retrieve the trouble codes and perform a thorough inspection of the cruise control system components.
