Driver Thorax Airbag Crash Sensor -G179- / Front Passenger Thorax Airbag Crash Sensor -G180-, REMOVING AND INSTALLING: Installing
Risk of malfunction.
- The door must be sealed properly for the crash sensor (pressure sensor) to function.
-- Engage the thorax airbag crash sensor in the door.
-- Turn the locking mechanism for the crash sensor clockwise.
- The tabs must engage audibly.
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 .
- Observe the safety precautions for the front thorax airbag crash sensors (pressure sensors). Refer to FRONT THORAX AIRBAG CRASH SENSORS (PRESSURE SENSORS) SAFETY PRECAUTIONS .
- 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.
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 .
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. Refer to Vehicle Diagnostic Tester.
