Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Fuse

Locate the fuse box and identify the cruise control fuse.
Use a fuse puller to remove the fuse and inspect it for continuity.
If blown, replace with a new fuse of the same amperage.

3. Inspect Brake Light Switch

Locate the brake light switch, usually positioned above the brake pedal.
Ensure the switch is properly adjusted and making contact when the pedal is pressed.
If faulty, remove the switch by disconnecting the electrical connector and unscrewing it from its mount.
Install a new switch and reconnect the wiring.

4. Test Throttle Position Sensor (TPS)

Use a multimeter to check the TPS for proper voltage readings.
Disconnect the TPS connector and measure the voltage output while moving the throttle.
If readings are outside the specifications, replace the TPS.

5. Check Wiring and Connections

Visually inspect the wiring harness and connectors for signs of wear, corrosion, or damage.
Repair or replace any damaged wiring or connectors to ensure proper electrical flow.

6. Test Cruise Control Module

Access the cruise control module, typically located under the dashboard.
Check for loose connections and visible damage.
If necessary, replace the cruise control module following the manufacturer's instructions.
