Solution

1. Preparation

Gather necessary tools and parts. Disconnect the vehicle's battery.
Tools Required: OBD-II scanner, multimeter, socket set, screwdriver set, and electrical contact cleaner.

2. Inspect and Replace the Cruise Control Switch

Remove the steering wheel cover using a screwdriver.
Disconnect the cruise control switch connector.
Use a multimeter to test the switch for continuity; replace if faulty.
Reconnect the switch and reassemble the steering wheel cover.

3. Check and Replace the Brake Pedal Switch

Locate the brake pedal switch under the dashboard.
Disconnect the electrical connector from the switch.
Test the switch with a multimeter; replace if it does not show continuity when the brake is pressed.
Reconnect the new switch and ensure it is properly adjusted to engage when the brake pedal is pressed.

4. Verify Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the sensor's electrical connector.
Use a multimeter to measure the resistance and output voltage as per the manufacturer's specifications; replace if out of range.
Reconnect the sensor and ensure it is securely fastened.

5. Inspect Vehicle Speed Sensor

Locate the vehicle speed sensor (usually on the transmission).
Disconnect the sensor's connector and check for proper voltage output using a multimeter; replace if defective.
Reconnect the sensor and secure it in place.
