Final Installation - Volkswagen 5NA 054 630 Manual De Montaje

 Attach the control unit -1- with the double-sided adhesive tape included in the scope of delivery.
 Connect the black single wire from the power wiring harness to the vehicle earthing point -arrow-.
 Unwind approximately 50 mm of the harness protective tape on the vehicle wiring.
 Cut the wire to the vehicle's reversing light.
 Identify the wires as per the vehicle's circuit diagram or with a voltage tester, e.g. on the connector for the tail light
 Crimp one end of the cut wire -2- in a crimp connector -3-.
 Crimp the free end of the cut wire -4- together with the red single wire -5- of the power wiring harness in the crimp
connector -3-.
 Heat-shrink the crimp connector -3- to seal it, using the hot air blower in the -VAS 1978- wiring harness repair set.
 Replace the harness protective tape.

Insert the free plug connector of the power wiring harness onto the buzzer.

 Degrease the fitting location of the buzzer -arrow- with a suitable cleaning agent.
 Attach the buzzer -arrow- with the double-sided adhesive tape included in the scope of delivery.
 Check the parking distance warning functions in accordance with the enclosed operating instructions.
If all of the parking distance warning functions work correctly, complete the final installation process Page 11.
If the parking distance warning system malfunctions, perform troubleshooting Page 11.
1.3 Troubleshooting
Note
If an internal error has been detected, the park distance control is non-functional.
If there is no tone after switching on the ignition and engaging reverse gear, check the power supply and the
connections to the control unit.
Page 5 - Figure 2
With reverse gear engaged, is the supply voltage to connector -1- 12V?
Is the buzzer connector plug connected correctly?
If an internal error is detected from the park distance control, an acoustic message is output. This comprises one
long error tone with low frequency followed by a series of acoustic signal tones. The output of the internal error is
carried out via the number of acoustic signal tones:
Long error +
number of signal tones
1
2
3
4
5
6
If several internal errors are detected, these are also reported acoustically, e.g. longer error tone and a signal tone
followed by three signal tones  Error Sensor 1 and Sensor 3 detected.
After issuing the error, the park distance control continually conducts a self test. Once all errors are eliminated, the
park distance control operates to its full capacity again.

1.4 Final installation

 Use the supplied cable ties to secure all of the parking distance warning system wiring to existing wiring or brackets
in the vehicle to prevent rattling noises.
 Reattach all of the trim elements in the reverse order.
