Self-test, function

Procedure

The Parktronic control unit (N62) carries out a self-test after the ignition is switched on.

The Parktronic control unit (N62), sensors and lines to the sensors are checked.

After the self-test all the active warning indicators are actuated fully for approx. t=2 seconds, as a result all the segments and the frames of the active warning indicators light up.

System o.k.

Model 168, 202, 208, 210, 215, 220

 The frames of the active warning indicators light up.

Model 163

 The first elements of the active warning displays light up at half brightness.

Malfunction

Model 168, 202, 208, 210, 215, 220

 All the red segments and the red parts of the frames on the active warning indicators light up.

Model 163

 All the red segments of the active warning displays light up.

If a warning indicator does not receive any valid signals within t=0.5 seconds after the ignition is switched on, the two red segments of the corresponding warning indicator light up. Thereupon a warning chime follows for approx. t=3 seconds and after t=20 seconds the warning indicator is switched off.

In operation the Parktronic control unit (N62) carries out system tests at regular intervals, in which parts of the Parktronic system (PTS) are checked.
