Solution

1. Preparation

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

2. Inspect and Replace Fuses

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Remove the cover and identify the cruise control fuse.
Check the fuse for continuity; replace it with a new fuse of the same amperage if blown.

3. Check and Replace Brake Light Switch

Locate the brake light switch, typically found near the brake pedal.
Disconnect the wiring harness from the brake light switch.
Remove the switch using the appropriate socket or wrench.
Install the new brake light switch, reconnect the wiring harness, and ensure it is adjusted correctly.

4. Test and Repair Cruise Control Switch

Remove the steering wheel cover to access the cruise control switch.
Inspect the switch for any visible damage or disconnections.
If damaged, replace the cruise control switch with a new one.
Reassemble the steering wheel cover securely.

5. Inspect and Replace Speed Sensor

Locate the speed sensor, usually found on the transmission.
Disconnect the wiring harness and remove the sensor using the appropriate tools.
Install the new speed sensor and reconnect the wiring harness.

6. Verify Throttle Actuator Operation

Inspect the throttle actuator for any obstructions or mechanical issues.
If faulty, remove it from the intake manifold, replace it with a new actuator, and reconnect all wiring.
