Troubleshooting Cruise Control Not Engaging on Volvo XC60 (2008-2017)

Tools Required

Repair Instructions

Step 1: Check the Cruise Control Switch

Access the Steering Wheel Controls:
- Remove the airbag module (if necessary) to access the cruise control switch. Refer to your vehicle repair manual for specific instructions on airbag removal.
Test the Switch:
- Using a multimeter, check the continuity of the cruise control switch. If it’s defective, replace it.

Step 2: Inspect the Brake Light Switch

Locate the Brake Light Switch:
- The switch is typically located on the brake pedal assembly.
Test the Switch:
- Disconnect the switch connector and use a multimeter to check for continuity when the brake pedal is not pressed. If there is no continuity, replace the switch.
Adjustment:
- If the switch is operational but misaligned, adjust its position so that it engages properly when the brake pedal is released.

Step 3: Check Vehicle Speed Sensor

Locate the VSS:
- The VSS is usually located on the transmission.
Test the Sensor:
- Using a multimeter, check the resistance of the sensor according to the specifications in the repair manual. If the readings are out of spec, replace the sensor.

Step 4: Review OBD-II Codes

Connect the OBD-II Scanner:
- Plug in the scanner and check for any stored trouble codes that may indicate a problem with the cruise control system or related components.
Clear Codes:
- If applicable, clear the codes and see if the cruise control engages. If codes return after clearing, or if the cruise control still doesn’t work, proceed to further diagnosis.

Step 5: Additional Checks

Inspect Fuses:
- Check the fuse box for any blown fuses related to the cruise control system.
Check Wiring:
- Inspect the wiring harness from the cruise control switch to the engine control unit (ECU) for any signs of wear or damage.

Conclusion

After following these diagnostic steps and repairs, test the cruise control system to ensure it functions correctly. If the problem persists, it may be necessary to consult a professional technician for further diagnosis, as more complex electronic issues may be at play.
