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 -arrow-.
- The retaining tab -3- must engage audibly.
- Follow all pyrotechnic components safety precautions, refer to PYROTECHNIC COMPONENTS SAFETY PRECAUTIONS .
- 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, for example.
-- Connect the connector -1- to the crash sensor until it clicks into place -arrow-.
-- Push the connector lock -2- to secure the connector.
The rest of the installation is performed in reverse order of removal, noting the following:
Make sure the connectors are installed correctly and are secure.
Make sure the wires do not get caught.
Ignition must be on when connecting 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 GND cable with the ignition turned on, refer to BATTERY, DISCONNECTING AND CONNECTING (A3 / A3 CABRIOLET) .
If the Airbag Indicator Lamp -K75- indicates a fault, check the Diagnostic Trouble Code (DTC) memory, erase it and check it again.
