Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface with the engine off.
Tools Required: OBD-II scanner, multimeter, socket set, screwdriver set.
Safety Warnings: Disconnect the battery before performing any electrical work.

2. Check Cruise Control Switch

Remove the steering column cover using a screwdriver.
Locate the cruise control switch connector and disconnect it.
Use a multimeter to check for continuity in the switch when pressed.
If the switch is faulty, replace it with a new one.
Reconnect the switch and secure the steering column cover.

3. Inspect Brake Pedal Switch

Locate the brake pedal switch under the dashboard.
Ensure the switch is properly adjusted and not sticking; it should return to its original position when the pedal is released.
If the switch is defective, replace it and adjust the new switch according to manufacturer specifications.

4. Verify Vehicle Speed Sensor

Locate the vehicle speed sensor on the transmission.
Disconnect the sensor and check the resistance using a multimeter; compare it with manufacturer specifications.
If the sensor is out of spec, replace it.
Reconnect the sensor and ensure it is securely mounted.

5. Inspect Cruise Control Actuator

Locate the cruise control actuator under the hood.
Check for any signs of damage or loose connections.
Test the actuator's functionality by applying power directly from the battery (if applicable); it should engage and disengage accordingly.
Replace the actuator if it does not operate correctly.

6. Reset the ECU

Reconnect the battery after all repairs are made.
Use the OBD-II scanner to clear any stored error codes.
Perform a reset of the vehicle’s ECU if necessary, following the manufacturer’s instructions.
