Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Check Speed Sensor
- Before starting inspections, inspect the safety around the vehicle.
- Lift up the vehicle as necessary.
- When the diagnostic trouble code is input in the VDCCM, perform the Clear Memory operation.
- Move the vehicle 2 to 3 meters (66 to 9.8 ft).
- Check that the numbers from the speed sensor are displayed.
Standard value: Vehicle speed is to be shown in numbers.
OK: Normal
NG: If vehicle speed is not displayed, check the signal line connection. If there are no problems, the unit could be faulty.
