⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems
•Allow engine to cool before opening engine components

Symptoms

•Cruise control system disengages without warning
•Cruise indicator light on the dashboard may flicker or turn off
•Inability to set or maintain a desired speed
•Sudden deceleration when cruise control is engaged

Solution

1. Preparation

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

2. Inspect and Replace Cruise Control Switch

Locate the cruise control switch on the steering wheel.
Remove the steering wheel cover using a socket set.
Disconnect the electrical connector from the cruise control switch.
Inspect the switch for any physical damage.
If damaged, replace it with a new switch and reconnect the electrical connector.

3. Test and Replace Cruise Control Relay

Access the engine compartment fuse box.
Locate the cruise control relay based on the owner's manual.
Remove the relay and test it using a multimeter for continuity.
If faulty, replace the relay with a new one.

4. Inspect and Adjust Throttle Position Sensor

Locate the throttle position sensor near the throttle body.
Disconnect the electrical connector from the sensor.
Using a multimeter, check the sensor's voltage output while manually adjusting the throttle.
If the readings are outside the specified range, replace the sensor.

5. Reassemble and Reconnect Battery

Ensure all components are securely reconnected.
Reattach any covers or panels removed during the repair process.
Reconnect the battery and ensure all connections are tight.
