Removing and Installing

Rear Parking Aid Sensor, Removing and Installing

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.

Removing

- Remove the rear bumper cover. Refer to Rear Bumper; Rear Bumper Assembly Overview.

• 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.

• Remove the sensor from the bracket first and then disconnect the connector from the sensor.

- Press the locking mechanisms - arrows - on the sensor holder - 1 - outward and pull the sensor - 2 - out of the sensor bracket toward the rear with the wires still connected.






When removing the sensor, make sure that the decoupling ring (black silicone ring) remains on the sensor head and does not remain in the bracket or get lost.

Do not bend the decoupling ring.

- Disconnect the connector - 2 - and remove the sensor - 1 -.






Installing

Install in reverse order of removal. Note the following:

• Do not bend the decoupling ring.

• Using a damaged decoupling ring can cause malfunctions.

• Replace any damaged decoupling rings.

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

Be sure to align the electric connection on the sensor when installing it.

Allocation of the parking aid sensor on the inside of the rear bumper cover:






1. RR - outer right

2. RRC - right center

3. LRC - left center

4. LR - outer left


When removing the sensor, make sure that the decoupling ring (black silicone ring) remains on the sensor head and does not remain in the bracket or get lost.

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 installation.






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.
