Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems to avoid shorts or shocks.
•Allow the vehicle to cool down before working on any components related to the engine or transmission.

Symptoms

•Cruise control indicator light not illuminating
•Inability to set or adjust the cruise control speed
•Engine speed fluctuates without maintaining a constant speed
•Unresponsive cruise control buttons on the steering wheel
•Possible check engine light illuminated

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any related issues.
2
Inspect the cruise control fuse for continuity and replace if blown.
3
Check the brake pedal switch operation to ensure it is not stuck or malfunctioning.
4
Verify the vehicle speed sensor (VSS) is functioning correctly by checking for proper voltage output.
5
Inspect the cruise control module for signs of damage or loose connections.
6
Check the wiring harness for any signs of wear, corrosion, or disconnections.

Solution

💡 Expert Tip

Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the cover and identify the cruise control fuse using the diagram on the fuse box cover.
Use a multimeter to test the fuse for continuity.
Replace the fuse if it's blown with one of the same rating.

3. Check and Replace Brake Pedal Switch

Locate the brake pedal switch, usually mounted on the brake pedal assembly.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity when the brake pedal is pressed.
If the switch is faulty, remove it by unscrewing or unclipping from the mount and replace it with a new switch.

4. Inspect Vehicle Speed Sensor (VSS)

Locate the VSS, typically found on the transmission.
Disconnect the wiring harness and remove the sensor using a socket set.
Inspect the sensor for damage and test it with a multimeter to ensure it outputs the correct voltage.
Replace the VSS if it is found defective.

5. Check Cruise Control Module

Locate the cruise control module, usually found near the steering column or under the dashboard.
Disconnect the module's electrical connectors and visually inspect for any damage or corrosion.
Reconnect and ensure all connections are secure. If issues persist, consider replacing the module.

6. Reassemble and Test

Reconnect any components that were removed during the inspection and repair process.
Reconnect the battery and perform a test drive to ensure the cruise control is functioning properly.
