Diagnostic help
A reading of the rear right wheel speed sensor can be obtained with the diagnostic tool.
- Select "Read values".

Current wheel speed in km/h (mph) is displayed.

With the rear wheels of the car raised, the diagnostic tool should read approximately 5 km/h (3.1 mph) if the rear right wheel is rotated by hand at about 1 rev./second.
^ For tracing electrical faults, the diagnostic tool can be used to take readings from the control module's wheel-sensor inputs.

- Select: "Wheel-sensor output"

The reading is used to determine whether the control module has lost contact with any of the wheel sensors. If there is contact, the value should be approximately 3.4 V DC.
