Parking Aid
• Additional information:
Refer to Owner's Manual.
In the Passat, an 8-channel parking aid system is installed with 4 ultrasonic sensors (parking aid sensors) in rear bumper and 4 ultrasonic sensors in front bumper and radiator protective grille.
The parking aid system monitors the vehicle periphery via ultrasonic sensors in the front and rear bumpers. The acoustic distance indicator sounds via two warning buzzers in the passenger compartment.
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 Front Parking Aid Sensor (G255)
• Left Front Center Parking Aid Sensor (G254)
• Right Front Center Parking Aid Sensor (G253)
• Right Front Parking Aid Sensor (G252)
• 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)
• Front Parking Aid Warning Buzzer (H22)
• Rear Parking Aid Warning Buzzer (H15)
• Parking Aid Button (E266)
• Parking Aid Switch Illumination (L117)
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:
Parking Aid Control Module (J446) is equipped with On Board Diagnostics (OBD) which assists troubleshooting.
The "Guided Fault Finding" function is to be used for troubleshooting of one of the systems described.
Perform output Diagnostic Test Mode (DTM) to test the parking aid system, refer to => [ Parking Aid Control Module Output Diagnostic Test Mode ] Component Tests and General Diagnostics.
