Self-test, function - GF54.65-P-2000R

MODEL 230 with CODE (220a) Parktronic system (PTS) 

Procedure 

After the ignition is switched on, the PTS control module performs a self-test. It tests the control module, the sensors and the leads to the sensors.

After the self-test, all active warning indicators are fully actuated for approx. 1 s, i.e. all the segments and frames of the active warning indicators light up.

System OK:

• The frames of the active warning indicators light up.

Operational problem:

• All red segments and the frames of the active warning indicators light up.

If a warning indicator receives no valid signals within 1/2 s of the ignition being switched on, the two red segments of the relevant warning indicator light up, a warning tone (lasting approx. 3 s) is activated and after 20 s the warning indicator is switched off.

During operation the control module performs system tests at regular intervals in which components of the Parktronic system (PTS) are tested.
