Parking Aid

• The rear lid assistant system is integrated in the parking aid system. Refer to=> [ Rear Lid Assistant (HDA) ] Rear Lid Assistant (HDA).

• Refer to the Owner's Manual.

General Description

The Eos has an eight-channel parking aid (PDC = park distance control) with 4 ultrasonic sensors (parking aid sensor) installed in the rear bumper, and 4 ultrasonic sensors in the front bumper.

The parking aid system monitors the vehicle periphery via ultrasonic sensors in the front and rear bumpers. An acoustic distance warning is given by 2 warning buzzers located in the vehicle interior.

Should a trailer be used (that is compatible with the factory-installed trailer wiring), the rear parking aid sensors are disabled. The front sensors remain active.

The 8-channel parking aid system consists of:

• Parking aid control module (J446)

• Left rear parking aid sensor (G203)

• Left rear center parking aid sensor (G204)

• Right rear center parking aid sensor (G205)

• Right rear parking aid sensor (G206)

• Right front parking aid sensor (G252)

• Right front center parking aid sensor (G253)

• Left front center parking aid sensor (G254)

• Left front parking aid sensor (G255)

• Front parking aid warning buzzer (H22)

• Rear parking aid warning buzzer (H15)

• Parking aid button (E266)

• Parking aid indicator lamp (K136)

Function

After switching on the ignition, a system self test (that lasts less that a second) is performed. The control module is now permanently operating, distance acquisition is activated.

When the parking aid system is ready, a short signal is sounded and the function light lights up. If a malfunction is detected in the system, a constant signal sounds for 5 seconds and the function lamp for parking aid system blinks.

During the distance measurement, the pauses between chime impulses get shorter as the gap between vehicles gets smaller. At proximity of less than 30 cm, a continuous tone is heard. Exception: Driving along a wall = no warning.

DTC Recognition and Display

The parking aid system is equipped with On Board Diagnostic (OBD) capabilities which assists in troubleshooting.

For fault finding, use the Vehicle diagnosis, testing and information system (VAS 5051B) in the "Guided fault finding" operating mode.

To check the entire parking aid system, perform the output diagnostic test mode.
