BMW 325i Air Bag Sensor

The BMW 325i Air Bag Sensor is the collision watchdog that instantly detects sudden deceleration and orders the inflatable restraints to fire and protect the occupants when a crash occurs. Within each BMW sedan of this line, the small electronic module nestles along with other parts of the restraint assembly, conducting a self-test every time the ignition is started so the light on the dash briefly shines to show that it is ready to go. Early 325i models were based on single-stage front impact units, with later model 325i generations adding smarter multi-axis crash detectors that read speed and direction more precisely. The Air Bag Sensor measures g-forces, sends an electric spark to the inflator canister, releases nitrogen gas, and fills the fabric bag in milliseconds. If the Air Bag Sensor fails, the cushion may never inflate at all, and a healthy Air Bag Sensor is vital for maintaining the trustworthiness of the supplemental restraint system. BMW made advances in materials over the decades, shifting from large gas bottles to small solid propellant charges that reduce weight and toxic byproducts. Owners of the recent 325i should heed the warning lamp; it flashes on after start-up to show the Air Bag Sensor and its partners passed the routine check to give any BMW driver quick proof the system is still ready.

A:
Wait for two minutes before you can disconnect the negative battery cable. Disconnecting airbag electrical connectors for driver's side either by using a T25 Tone screwdriver that is inserted through the hole in the front-side of the steering wheel or by inserting a T20 Tone screwdriver through the hole in the base of the steering wheel. Don't forget to do all this again on the other side. In both cases, while you are handling an airbag module, make sure that it is not pointed towards your body when opening and never put it on any surface with its opening facing downwards. Push on and then connect back electrical connectors and insert airbag until locked. For passenger's side air bag remove glove box, pry up locking catch and unplug airbag electrical connector(s). Take off nuts which fixate retaining mechanism and remove air bag from vehicle part. The installation takes place as described above but backwards than how removal was done; control unit arrow should be pointed towards front of a car. To extract impact sensors, take out suitable trim panels along with insulation materials. When these devices are getting removed from automobile just unscrew bolts and disconnect them via electric block respectively. Fasten all screws tightly according to prescribed torque rate when you tighten their bolts up after completing each step of work described above.
