Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace Cruise Control Switch

Remove the airbag module from the steering wheel:
- Use a torque wrench and appropriate socket to remove the screws securing the airbag.
- Carefully disconnect the airbag connector.
Remove the steering wheel cover and access the cruise control switch.
Inspect the switch for damage.
If damaged, disconnect the wiring harness and replace the cruise control switch with a new one.

3. Check and Replace Brake Pedal Switch

Locate the brake pedal switch above the brake pedal.
Disconnect the wiring harness from the switch.
Test the switch using a multimeter; replace if it does not operate correctly.
To replace, remove the switch from its mounting bracket and install the new switch. Reconnect the wiring harness.

4. Inspect Vehicle Speed Sensor

Locate the vehicle speed sensor on the transmission.
Disconnect the wiring harness and remove the speed sensor.
Clean the mounting area and inspect the sensor for damage.
Replace with a new speed sensor if faulty. Reconnect the wiring harness.

5. Check Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Inspect the fuses related to the cruise control system (refer to the owner’s manual for specific fuse locations).
Replace any blown fuses with the same amperage rating.
