There are several potential causes when your 2003 Honda Accord cruise control stops functioning correctly:
Reasons 1: Blown Fuse
One of the easiest issues to check is a blown fuse. Locate the fuse box and check the fuse corresponding to the cruise control system. Fuses commonly blow when electrical systems are overloaded. Replace the fuse with one of the same amperage rating.
Reasons 2: Damaged Vacuum Lines
Older Honda Accords use a vacuum system to operate the cruise control. Any cracks or disconnects in the vacuum lines can prevent the system from working properly. Inspect all visible vacuum lines under the hood for damage. Replace any deteriorated hoses.
Reasons 3: Faulty Brake Light Switch
The brake light switch disengages the cruise control when the brake pedal is pressed. If the switch malfunctions, it can cause cruise control problems. Test the switch for continuity with a multi-meter when pressed and released. Replace if faulty.
Reasons 4: Speed Sensor Failure
The vehicle speed sensor provides key data to the cruise control module. If it fails, the cruise control will be disabled. Inspect connections to the sensor and test it with a multi-meter. Replace if not functioning properly.
Reasons 5: Cruise Control Module Failure
Like many electronic systems, the cruise control has a dedicated control module. If it fails, the entire system will be disabled. Unfortunately, modules cannot be tested or repaired, only replaced.
Reasons 6: Cable Damage
The physical cable that runs from the cruise control module to the throttle body can become damaged over time. This prevents cruise control activation. Inspect the cable routing and replace if worn or damaged.
How to Diagnose 2003 Honda Accord Cruise Control Problems?
Diagnosing cruise control issues requires methodically testing components and electrical circuits. Here are some steps:
1. Check for Diagnostic Codes
Use an OBD-II scanner to check for any diagnostic trouble codes stored in the cruise control module. Codes can directly point to faulty components.
2. Test Fuses
As mentioned before, check all fuses related to the cruise control system using a test light or multi-meter. Replace any blown fuses.
3. Inspect Wiring
Look for damaged or disconnected wiring and connectors related to the cruise control. Common areas to check include the brake light switch, under the hood, and around electronic modules.
4. Check Vacuum System
Use a hand-held vacuum pump to test the vacuum actuators and lines. Replace any damaged or leaking components.
5. Test Sensors and Switches
Check sensor readings with a multi-meter. Test switch continuity when actuated. Replace sensors or switches that are out of specification.
6. Monitor Module Signals
Use a diagnostic scanner to monitor cruise control module data signals during operation. Compare them to factory specifications to pinpoint faults.
Following these diagnosis steps will help narrow down the root cause of your 2003 Honda Accord cruise control problems.
Troubleshooting from Personal Experience
In addition to the general diagnosis steps outlined earlier, here are some firsthand troubleshooting tips based on fixing this issue on a 2003 Honda Accord:
- Check the fuses first, as this is an easy item to inspect. Specifically check fuse #13 in the engine compartment and fuse #18 in the under-dash fuse box on V6 models. For 4-cylinder models, check fuse #22 and #23 in the engine bay along with fuse #18 inside.
- The cable reel inside the steering column could potentially be faulty. This reel is located behind the airbag and connects to the cruise control module. Expect a repair cost around $89 for the part and $150 for labor if going through a dealership. The part can be found cheaper online, around $120.
- The brake light switch under the brake pedal is another reported culprit. You can test it by pushing up on the pedal while engaging cruise control to see if it holds or disengages. Replace the switch if it seems to be impacting cruise function.
Starting with these tips could help isolate the problem more quickly compared to a general diagnosis.

How to Reset 2003 Honda Accord Cruise Control
If you’ve resolved a minor electrical issue, the cruise control system may just need to be reset. Here is the reset procedure:
- Turn the ignition key to the “On” position but do not start the engine.
- Press the “Resume/Accel” button on the steering wheel and hold it for 10+ seconds until you hear a beep.
- Release the button and then press it again and hold for another 10+ seconds until you hear another beep.
- Turn the ignition key to the “Off” position.
- Start the vehicle and test cruise control operation.
The cruise control module should now be reset to factory defaults. Be sure to fully test operation after resetting the system.
Professional Diagnosis
If you cannot resolve the cruise control issues on your 2003 Honda Accord through basic troubleshooting, have the vehicle professionally diagnosed. Dealerships and shops have advanced diagnostic scanners to assess the electronic modules and sensors.
They also have the expertise to test electrical circuits and mechanical components. While this does come with added cost, it may be required to correctly identify and repair the root cause.
Replace Failed Components
Once you’ve determined the source of the problem through diagnosis, you can replace the failed parts. Control modules, sensors, switches, vacuum actuators, and all other cruise control components are available as direct replacements through dealerships and auto parts stores. Only replace confirmed faulty parts to avoid unnecessary costs.
Is It Safe to Drive With Cruise Control Problems?
A malfunctioning cruise control system can potentially be dangerous to operate. The cruise control may disengage unexpectedly while driving, causing sudden deceleration. Or it could potentially remain stuck on, not allowing you to decelerate properly.
Use caution when driving with any cruise control issues and have it repaired promptly. Only drive as needed until repairs can be made. Avoid using the cruise control feature when problems exist.
FAQ About 2003 Honda Accord Cruise Control:
Where is the cruise control fuse in a 2003 Honda Accord?
The cruise control fuse is typically fuse #18 in the interior under-dash fuse box. It is a 10A fuse that protects the entire system.
What does a faulty brake light switch cause with cruise control?
A malfunctioning brake light switch can prevent cruise control engagement or cause it to disengage as soon as the brake is pressed. This provides faulty signals to the cruise control module.
Can a bad speed sensor disable cruise control?
Yes, the vehicle speed sensor provides key data to the cruise control system. If it is providing incorrect or erratic readings, it can disrupt proper cruise control function.
How much does it cost to replace a failed cruise control module?
Cruise control module replacement typically costs $350-700 for parts and labor. The module itself is around $250-500. Prices vary by year, make and model.
The Bottom Line
While cruise control problems can be frustrating, there are systematic ways to diagnose the issue in your 2003 Honda Accord. By methodically testing fuses, wires, vacuum lines, sensors and switches, you can narrow down the fault. Reset procedures may also get it working again after minor issues.
For continued problems, professional diagnosis at a repair shop is recommended to properly identify any failed components. With some time and diligence, you can likely get your 2003 Honda Accord cruise control functioning correctly again.
