GF54.65-P-2000SK Self-Test, Function
- with CODE (220) 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.

Fault 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.
