Checking The Connectors For The Control Module And Wheel Sensor
- Ignition off
- Check the wheel sensor and control module connectors. Check for contact resistance and oxidation
- Reinstall the components, reconnect the connectors etc.
- Raise the car so that the relevant wheel is clear of the ground
- Ignition on
- Read off the wheel speed for the relevant wheel.
Spin the relevant wheel and check that the wheel speed is updated.
If the wheel speed is updated, the cause of the fault was loose connections in the connectors for the control module or wheel sensor.
NOTE:The speed signal will only be active for approximately 20 seconds. Activate the function again if necessary.
