Driver And Front Passenger Side Pedestrian Protection Crash Sensor 2 -G851- And -G852-, Removing And Installing, Vehicles Through My 2016: Installing
- Follow all safety precautions when working on 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.
-- Position the pressure hose -2- at the center of the color mark -3- in the recess on the specified marking -4- in the molded foam part -1-.
There are pressure hoses -2- without and with the color mark -3-.
For a pressure hose -2- without a color mark -3-, measure the center and mark.
-- Position the pressure hose evenly in both directions -arrows- in the recess in the molded foam part.
Do not kink or stretch the pressure hose.
-- Install the molded foam part with the pedestrian protection crash sensors. Refer to FRONT BUMPER COVER, REMOVING AND INSTALLING .
-- Install the pedestrian protection crash sensor -4- with expanding rivets -3, and 5- on the bracket.
-- Fasten the molded foam piece -1- at the left and right with a cable tie -2- on the bracket, the cable tie head -arrow- must sit at the bottom the molded foam piece.
-- 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:
Make sure the connectors are installed all the way and engage audibly.
Make sure the wires do not get caught.
The ignition must be on when connecting the battery. If pyrotechnic components (for example, airbag, belt tensioner) are not repaired correctly, they may deploy unintentionally after connecting battery. There must not be anyone inside the vehicle when connecting the battery.
-- Connect the battery ground cable with the ignition switched on. Refer to BATTERY, DISCONNECTING AND CONNECTING .
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.
If the Airbag Indicator Lamp -K75- indicates a fault, check the DTC memory, erase it and check it again using the Vehicle Diagnostic Tester.
