Solution

1. Preparation

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

2. Check and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use a fuse puller or needle-nose pliers to remove the cruise control fuse.
Inspect the fuse for any signs of damage. If blown, replace it with a fuse of the same amperage rating.
Reconnect the battery.

3. Test and Replace Switches

Locate the brake and accelerator pedal switches.
Use a multimeter to check for continuity at the switches when pressed.
If either switch is faulty, remove the old switch and install a new one, ensuring proper alignment and connection.

4. Inspect and Clean Cruise Control Module

Access the cruise control module, typically located near the engine compartment.
Disconnect the wiring harness from the module.
Inspect for any corrosion or damage; clean connectors using electrical contact cleaner if necessary.
If the module is damaged, replace it with a new one.

5. Verify Vehicle Speed Sensor

Locate the vehicle speed sensor, generally near the transmission.
Check the sensor's wiring for damage.
Use a multimeter to measure the sensor’s output; replace it if it does not meet specifications.
