Driver Side Airbag Crash Sensor -G179- / Front Passenger Side Airbag Crash Sensor -G180-, REMOVING AND INSTALLING: Installing
For proper crash sensor (pressure sensor) function, ensure door does not leak.
-- Pay attention that the seal -2- is seated correctly. Replace crash sensor if damaged or deformed
-- Engage the side airbag crash sensor in the door.
-- Turn the locking mechanism -1- for the crash sensor clockwise in direction of -arrow-.
- The retaining tab -3- must engage audibly.
- Follow all safety precautions when working on pyrotechnic components. Refer to SAFETY PRECAUTIONS FOR PYROTECHNIC COMPONENTS .
- Follow the safety precautions for front side airbag crash sensors (pressure sensors). Refer to FRONT SIDE AIRBAG CRASH SENSORS (PRESSURE SENSORS) SAFETY PRECAUTIONS .
- Before handling pyrotechnic components (for example, connecting the connector), the person handling it must "discharge static electricity". This can be done by touching the door striker pin, for example.
-- Connect the connector -1- to the crash sensor until it clicks into place in direction of -arrow-.
-- Push in the connector lock -2- to secure the connector.
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 turned 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.
