Diagnostic help
^ FL wheel speed sensor signal can be read using diagnostic tool.
- Select "Read values".
- Select "Wheel Speed Front Left ".

The current wheel speed in km/h is displayed.

With the front of the car raised off the ground, the diagnostic tool should show a reading of about 5 km/h when the FL wheel is rotated by hand at a speed of about one turn a second.
^ For tracing electrical faults, the diagnostic tool can be used to take readings from the control module's wheel-sensor inputs.
- Select "Read values"
- Select "Wheel-sensor output"

The reading is used to determine whether there is a break in the circuit between the control module and one of the wheel sensors. If the circuit is OK, the reading should be approximately 3.4 V.
