Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and flathead screwdriver.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the battery to prevent any electrical shorts during repairs.

2. Inspect and Replace Fuses

Locate the fuse box in the passenger compartment or engine bay.
Use the diagram on the fuse box cover to identify the cruise control fuse.
Remove the fuse using a fuse puller or flathead screwdriver and inspect it for continuity.
If blown, replace it with a fuse of the same amperage rating.

3. Test and Replace Brake Pedal Switch

Locate the brake pedal switch, usually mounted above the brake pedal lever.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity. Press the brake pedal while testing.
If the multimeter does not register continuity, replace the brake pedal switch.

4. Inspect Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Check for carbon buildup or obstruction inside the throttle body.
Clean the throttle body using throttle body cleaner and a cloth.
Reassemble the intake duct securely.

5. Check Steering Wheel Controls

Remove the airbag cover and steering wheel if necessary (follow manufacturer guidelines).
Inspect the wiring harness connected to the cruise control switches for damage.
Use a multimeter to test the switch functionality.
Replace the cruise control switch if it is defective.
