Repair Instructions

Addressing the Brake Pedal Switch:
- If the switch is faulty, remove it by disconnecting the electrical connector and unscrewing it from the bracket.
- Install a new switch and reconnect the electrical connector. Test to ensure proper operation.
Replacing the Throttle Position Sensor (if necessary):
- Disconnect the negative battery terminal to prevent any electrical shorts.
- Remove any components obstructing access to the TPS.
- Disconnect the wiring harness from the TPS and remove the screws holding it in place.
- Install the new TPS, ensuring it’s mounted securely, and reconnect the wiring harness.
- Reconnect the battery and test the cruise control system.
Replacing the Cruise Control Module (if faulty):
- Disconnect the battery.
- Remove any panels necessary to access the cruise control module.
- Disconnect the electrical connectors from the module.
- Unscrew the module from its mounting location and remove it.
- Install the new module by reversing the removal steps. Ensure all connections are secure.
- Reconnect the battery and test the system.
Rechecking the System:
- After repairs, start the vehicle and test the cruise control system to ensure it activates and maintains speed without disengagement.
- Clear any DTCs using the OBD-II scanner if present.
Final Check:
- Test drive the vehicle to confirm that the cruise control functions properly under various conditions (different speeds and inclines).

Conclusion

With careful diagnostics and repair following the above steps, you should be able to restore functionality to the cruise control system in your 2013 Volvo XC60. If the system remains inoperative after these steps, consider consulting a professional technician for further diagnosis, as there may be more complex issues at play.
