Parktronic Malfunctions and Faults

This is an overview of Parktronic malfunction and fault scenarios, respectively.

Malfunction Scenario 1

Malfunctions are indicated with double red (4 LEDs) warning elements and no warning tone (Figure 1).

An entry is not saved in fault memory.

Malfunctions can be triggered by external ultrasonic signals:

^ Compressed air

^ Drier blower for a washer system

^ Rail vehicles

^ Brake squeal on vehicle or a nearby vehicle

Or through:

^ Soiling of sensors with ice or snow

^ License plate brackets

Fault Scenario 2

Faults are indicated in the Parktronic warning elements with double red (4 LEDs) with warning tone (Figure 1) (see arrows).

An entry is saved in fault memory.

The sensor function is automatically checked while driving at between 22-37 mph. If a fault occurs when driving, then this is issued at a speed less

than 9 mph with double red lights and warning tone.

The following applies to both scenarios:

If a malfunction or a fault is present for more than 2 seconds, the display in the warning elements goes out and the PARKTRONIC OFF button in the

UCP lights up in red.

Diagnosis

To fix issues that cannot be clearly located via fault codes in fault memory, check for correct and central installation (Figure 3) (C) or for any

damage caused by stone chipping (Figure 2) (A) (B).

The decoupling ring must be centered and custom fit when installed (Figure 3) (C) and Figure 4 (C). Refer also to S-B-54.651251 Parktronic Sensor
