Rear Parking Aid Sensors

Rear Parking Aid Sensors

Special tools, testers and auxiliary items required

• Release Tool (T10345)

Sensor in the rear bumper cover:

• Left Rear Center Parking Aid Sensor (G204)

• Left Rear Inner Parking Aid Sensor (G334)

• Right Rear Inner Parking Aid Sensor (G335)

• Right Rear Center Parking Aid Sensor (G205)

• Due to different software versions, different sensor names may be displayed in the first Parking Aid Control Module (J446) software version. If this is the case, the follow allocation applies:

• Left Rear Center Parking Aid Sensor (G204) is Left Rear Parking Aid Sensor (G203)

• Left Rear Inner Parking Aid Sensor (G334) is Left Rear Center Parking Aid Sensor (G204)

• Right Rear Inner Parking Aid Sensor (G335) is Right Rear Center Parking Aid Sensor (G205)

• Right Rear Center Parking Aid Sensor (G205) is Right Rear Parking Aid Sensor (G206)

Removal and installation is the same for all sensors so the following information describes only one of them.


• Turn off the ignition and all electrical consumers.

• Remove the key.

Removal

- Remove the rear bumper cover.


• Always follow the sequence for removing the sensor.

• Otherwise, the sensor may be damaged. Hairline cracks which lead to sensor failure can develop if too much force is used on the sensor.

• First remove the sensor from the bracket and then disconnect the sensor connectors.

- Open the tabs - arrows - with (T10345) and remove the sensor from the bumper cover with the connector still connected.






- Disconnect the connector - arrow - when it is removed.






Installation

Installation is performed in the reverse order of removal. Note the following:


• Do not bend the coupling ring.

• Using a damaged coupling ring can cause malfunctions.

• Replace damaged coupling rings.

• Sensor brackets are designed in different shapes and must be matched to the respective component location in the bumper cover.

• Pay attention to the connectors when installing the sensors.

• When installing the sensor, make sure the coupling ring (black silicone ring) is mounted on the sensor head correctly and that it does not fall off or become jammed when inserting into the sensor bracket.

• Both retaining tabs on the sensor must engage audibly in the sensor bracket when installing.

- Make sure the sensor is seated correctly in the bracket after installing. Dimension - a - for the circular gap between the sensor head and sensor bracket must be even all around on the outer side of the bumper cover.
