Pressure Hose Sensor for Front Pedestrian Protection -G579-, REMOVING AND INSTALLING: Installing
- Follow all safety precautions when working on pyrotechnic components. Refer to SAFETY PRECAUTIONS FOR 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 groove 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 equally in both directions -arrows- in the groove in the molded foam part.
Do not kink or stretch the pressure hose.
-- Insert the pressure hose -4- in the groove in the molded foam part -3- and engage in the bumper cover.
-- Equipped on some models: engage the crash sensor -5- for the pedestrian protection in the bumper cover and install with the expanding rivet -2-.
-- Connect the connector -1-.
-- Connect 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 after assembling, check the DTC memory, erase it and check it again using the Vehicle Diagnostic Tester
