Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the cruise control fuse using the diagram on the fuse box cover.
Use a multimeter to check for continuity; replace with the same amperage fuse if necessary.

3. Test and Replace Brake Pedal Switch

Locate the brake pedal switch mounted on the brake pedal arm.
Disconnect the electrical connector from the switch.
Test the switch with a multimeter for continuity when the pedal is pressed.
Replace the switch if it does not function correctly.

4. Inspect Steering Wheel Controls

Remove the airbag module from the steering wheel following manufacturer’s procedures.
Check for loose connections or damaged wires in the cruise control buttons.
Repair or replace any damaged components before reassembling.

5. Test Throttle Position Sensor (TPS)

Locate the TPS on the throttle body.
Disconnect the electrical connector and use a multimeter to check the voltage output.
Replace the TPS if readings fall outside specified manufacturer ranges.

6. Reassemble and Reconnect Battery

Reconnect all components and wiring that were disconnected during inspection.
Reinstall the airbag module and any trim pieces removed for access.
Reconnect the negative battery terminal.
