Driver And Front Passenger Side Pedestrian Protection Crash Sensor 2 -G851- And -G852-, Removing And Installing, Vehicles From My 2017: Installing

WARNING:

Risk of injury due to involuntary deployment.

Pay attention to the safety precautions when working with pyrotechnic components. Refer to SAFETY PRECAUTIONS WHEN WORKING WITH PYROTECHNIC COMPONENTS .
Before handling pyrotechnic components (for example, connecting a connector), the person handling it must "discharge static electricity". For example, this can be done by briefly touching the door striker.

NOTE:

The pedestrian protection crash sensor cannot be replaced separately. If faulty, replace it with the molded foam part.

WARNING:

Risk of malfunction.

Do not kink, twist or stretch the pressure hose.

The pressure hose must be inserted without any tension.

-- Install the molded foam part with the pedestrian protection crash sensor. Refer to MOLDED FOAM PART, REMOVING AND INSTALLING, A3 / FRONT BUMPER COVER, REMOVING AND INSTALLING .

-- Attach the connector -1- to the crash sensor until it clicks into place -arrow-.

-- Push in the connector lock -2- to secure the connector.

Further installation is performed in reverse order of removal, while noting the following:

NOTE:

Make sure the connectors are pushed in all the way and that they engage audibly.

Make sure the wires are not pinched.

WARNING:

Repairing pyrotechnic components (for example the airbag and seat belt tensioner) incorrectly increases the risk of injuries due to unintentional deployments when the battery is connected.

The ignition must be on when connecting the battery.
Make sure that no one is inside the vehicle at the time when the battery is connected.

-- Connect the battery ground cable with the ignition switched on. Refer to BATTERY, DISCONNECTING AND CONNECTING .

WARNING:

Repairing pyrotechnic components (for example the airbag and seat belt tensioner) incorrectly increases the risk of injuries due to unintentional deployments when the ignition is switched on.

If the ignition is not switched on after the battery is reconnected - >>indicator lamps in the instrument cluster do not light up<< - the ignition (key/button) may only be switched on when the driver seat is positioned all the way back.

NOTE:

If the Airbag Indicator Lamp -K75- indicates a fault, check the DTC memory, erase it and check it again using the Vehicle Diagnostic Tester.
