On the highway or during extended trips, cruise control is a practical feature that enables drivers to keep their speed constant through the use of a pre-set threshold. However, when the cruise control system in a 2003 Honda Accord stops working, it can be both frustrating and dangerous.
In this article, we will explore the common causes of 2003 Honda Accord Cruise Control Not Working and provide solutions to help fix the problem.
Why Is My 2003 Honda Accord Cruise Control Not Working?
These are the common causes that play a significant role in the 2003 Honda accord cruise control not working:
- Damaged Vacuum Actuator/Hoses/Cable
- Failing Speed Sensor
- Failing Brake Pedal Switch
- Bad Fuse
- Failed Cruise Control Module
Cause 1: Damaged Vacuum Actuator/Hoses/Cable
For controlling the speed of the cruise control system in older vehicles, such as the Honda Accord from 2003, a vacuum actuator and a cable that is connected to the throttle are used. If the vacuum actuator or hoses become damaged, the system may fail, and the cruise control will not work.
It is also possible that the link that connects the actuator and the throttle has been damaged, which would result in the system failing.
Cause 2: Failing Speed Sensor
In addition to regulating the flow of fuel and the timing of the ignition, one of the functions of a speed sensor is to indicate the speed at which the vehicle is traveling. If the speed sensor fails, the cruise control will not work, and there is a chance that the speedometer will not work either. Additionally, the engine might have a harder time staying at a steady idle.
Cause 3: Failing Brake Pedal Switch
When the brake pedal is depressed, the switch on the brake pedal will turn on the brake lights, and because it is wired to the brake pedal, it will also disengage the cruise control function. If the pedal switch fails, the car may assume the brakes are engaged and refuse to let the cruise control work.
Cause 4: Bad Fuse
The cruise control system in the 2003 Honda Accord has a corresponding fuse, as do many of the car’s electronic systems. The cruise control will be disabled in the event of a short circuit, which will cause the fuse to blow.
Cause 5: Failed Cruise Control Module
The cruise control module is responsible for maintaining the set speed and can become worn out or damaged over time. If the module fails, the cruise control will not work, and the driver will need to replace it in order to regain its function.
Solutions: 2003 Honda Accord Cruise Control Is Not Working
Check for Damaged Vacuum Actuators/Hoses/Cable
If you suspect that the vacuum actuator or hoses may be damaged, take your car to a qualified mechanic. They will be able to perform diagnostic tests on the various components of the system in order to identify the root of the issue and carry out any necessary repairs.
Replace the Failing Speed Sensor
If the speed sensor is found to be the cause of the problem, it will need to be replaced. A competent mechanic will be able to diagnose the problem and then replace the sensor.
Replace the Failing Brake Pedal Switch
If the brake pedal switch is found to be the cause of the problem, it will need to be replaced.
Replace Bad Fuse
If a fuse is found to be the cause of the problem, it will need to be replaced.
Replace Failed Cruise Control Module
If the cruise control module is found to be the cause of the problem, it will need to be replaced.
Why Is My Cruise Control Not Working On My Honda Accord?
There are several potential reasons why your Honda Accord’s cruise control might not be working. Common issues include a malfunctioning control module, sensor or switch problems, or throttle actuation issues. These problems can disrupt the cruise control system’s functionality, causing it to fail.
Additionally, some Honda Accord models may experience radio and climate control display issues, where these components go dark. To address these problems, it’s advisable to consult with a technician at a RepairPal Certified shop near you for a thorough diagnosis and repair.
How Do You Reset The Cruise Control On A Honda Accord?
Resetting the cruise control on a Honda Accord, particularly if it features Adaptive Cruise Control (ACC), is a straightforward process. To reset the ACC system, press and hold down the interval button (typically depicted as a vehicle with four bars behind it) for approximately one second.
When successful, the instrument panel will display “Cruise Mode Selected.” To reset the Adaptive Cruise Control feature, press and hold the interval button again. This simple procedure allows you to regain control over your cruise control system.
Why Will My Cruise Control Turn On But Not Set?
When your cruise control turns on but fails to set, it is often indicative of underlying issues such as a malfunctioning fuse or a disruption in communication within your vehicle’s computer system. In the case of communication disruption, you may need to replace the vehicle’s speed control assembly to rectify the problem and restore proper cruise control functionality.
Can I Add Cruise Control To My Car?
Adding cruise control to a car is possible, but the feasibility largely depends on the vehicle’s make and model. Aftermarket cruise control kits are available for older cars that don’t rely on an Electronic Control Unit (ECU) to manage engine functions.
However, it’s important to note that retrofitting cruise control to a car that wasn’t originally equipped with it may not offer the same seamless operation as factory-installed systems found in modern vehicles. The complexity of the installation process can vary, so it’s advisable to consult with a qualified technician or installer for guidance and a successful installation.
