Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is turned off.
  • Disconnect the battery to prevent electrical shorts.
2. Inspect and Replace the Cruise Control Switch
  • Remove the steering wheel cover using a socket set.
  • Disconnect the cruise control switch wiring harness.
  • Inspect the switch for damage; replace if necessary.
  • Reconnect the wiring harness and reassemble the steering wheel cover.
3. Test and Adjust the Brake Pedal Switch
  • Locate the brake pedal switch mounted on the brake pedal assembly.
  • Check for proper operation by pressing the brake pedal and ensuring the switch activates.
