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

MODEL 171.4 with CODE (220a) Parktronic System (PTS)

Self-test, function

Once the ignition is switched on (circuit 15 On) the Parktronic control unit (N62) carries out a self-test.

The following are checked:

PTS control module (N62)
Center instrument panel PTS warning indicator (A44/4)
Rear PTS warning indicator (A44/3)
PTS sensor unit, front bumper (A42)
PTS sensor unit, rear bumper (A43)
Complete wiring

After the self-test the center instrument panel PTS warning indicator (A44/4) and rear PTS warning indicator (A44/3) is fully actuated for approx. 1 second, i.e. all the LEDs light up.

If there are no faults and malfunctions present, the outer LEDs of the center instrument panel PTS warning indicator (A44/4) and rear PTS warning indicator (A44/3) are actuated with reduced brightness. The Parktronic system (PTS) is operational.

The Parktronic control unit (N62) carries out further self-tests at regular intervals.

In this process the Parktronic system (PTS) distinguishes between a malfunction and a fault.

Malfunction

If a malfunction occurs during operation, this is displayed by the lighting up of the red LEDs on the center instrument panel PTS warning indicator (A44/4) or rear PTS warning indicator (A44/3) affected. No warning chime is emitted.

A malfunction can be caused by a defect in a component of the Parktronic system (PTS) or a short-term interference from outside (e.g. induction loop).

Fault

If during a self-test while driving a fault continues to be detected, the next time the speed drops below 16 km/h the red LEDs of the center instrument panel PTS warning indicator (A44/4) or rear PTS warning indicator (A44/3) are actuated and in addition a warning chime is emitted for approx. 3 seconds.

After a further 20 seconds the Parktronic system (PTS) switches off and the fault is stored in the fault memory of the Parktronic control unit (N62).
