Front Airbag Crash Sensor -G190-, REMOVING AND INSTALLING: Installing
- Observe the safety precautions for pyrotechnical 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.
-- 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 pushed in all the way and that they engage audibly.
Make sure the wires are not pinched.
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 in the vehicle interior when connecting the battery.
-- Connect the battery ground cable with the ignition switched on. Refer to BATTERY, DISCONNECTING AND CONNECTING .
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 .
