Check with the temperature probe
Note
• The function of the heating for the rear window can be checked with a temperature probe with digital
display (see Workshop Equipment Manual).
• The indicator light in the rocker switch also lights up if a fault is present and the heating wires in the
rear window do not warm up!
The tip of the sensor is used to measure from the outside on the centre of the rear window.
Note
• The heating wire on the rear window must run exactly under the tip of the sensor for this
measurement procedure!
• After switching on at room temperature and a period of 2 minutes, the temperature must increase by
approx. 2 degrees!
• If no temperature increase is shown, the fault must be detected on the basis of the wiring diagram!
