Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, screwdriver set, replacement fuses (if needed), brake pedal switch (if faulty).
Ensure the vehicle is parked on a level surface with the engine off. Disconnect the battery before starting any electrical work.

2. Inspect and Replace the Brake Pedal Switch

Locate the brake pedal switch: It's typically found near the top of the brake pedal arm.
Test the switch: Use a multimeter to check for continuity when the brake pedal is pressed. If it does not show continuity, replace the switch.
Remove the faulty brake switch: Disconnect the wiring harness and unscrew the switch from its mounting.
Install the new brake switch: Secure it in place and reconnect the wiring harness.

3. Check and Replace Fuses

Locate the fuse box: Typically under the dashboard or in the engine compartment.
Inspect fuses related to the cruise control: Use the diagram on the fuse box cover to identify the relevant fuses.
Replace any blown fuses: Pull the fuse using fuse pullers and insert a new fuse of the same rating.

4. Repair or Replace the Cruise Control Lever

Remove the steering column cover: Unscrew and carefully detach the plastic covers.
Inspect the cruise control lever: Check for any signs of damage or corrosion in the wiring.
Replace the lever if necessary: Disconnect the wiring harness and install a new cruise control lever.

5. Reconnect Battery and Test

Reconnect the vehicle’s battery and check if the cruise control system is now operational.
