Diagnostic Steps

1
Scan the vehicle’s onboard computer using an OBD-II scanner for any diagnostic trouble codes (DTCs)
2
Check the brake pedal switch operation and adjustment; ensure it’s correctly aligned and functioning
3
Inspect the cruise control lever or button for physical damage or malfunction
4
Verify the vehicle speed sensor (VSS) function by monitoring the speed reading on the instrument cluster
5
Check the vehicle’s fuse box for any blown fuses related to the cruise control system
6
Ensure that the throttle body is clean and functioning properly, as it directly impacts cruise control operation

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Inspect Brake Pedal Switch

Locate the brake pedal switch, usually found above the brake pedal.
Check if the switch is properly aligned and making contact when the pedal is pressed.
If faulty, remove the switch by releasing the retaining clip and disconnecting the wiring harness.
Replace with a new brake pedal switch and reattach.

3. Check Cruise Control Lever/Button

Remove any trim panels if necessary to access the cruise control lever/button.
Inspect for physical damage or wear.
If defective, disconnect the wiring harness and replace the lever/button assembly.

4. Verify Vehicle Speed Sensor (VSS)

Locate the VSS, typically mounted on the transmission.
Disconnect the electrical connector and inspect for corrosion or damage.
Use a multimeter to measure the VSS output; refer to the service manual for specific voltage readings.
Replace the VSS if it does not meet specifications.

5. Inspect Fuses

Open the fuse box and locate the cruise control fuse (refer to the owner's manual for the exact location).
Remove the fuse and inspect it for continuity.
Replace with a new fuse of the same amperage if blown.

6. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reassemble the intake duct and ensure all connections are secure.
