Air Bag Crash Sensor Module Removal Procedure
printer friendly version

Description:

Four ELVS Members (Audi, Mercedes-Benz, Toyota, and Volvo) manufactured vehicles during the model year period from 1984 to 1993 that contained Air Bag Crash Sensor Modules with mercury switches.

There is only one Air Bag Crash Sensor Module in a vehicle, typically containing two mercury switches.

IMPORTANT: Mercury switches are contained only in the Air Bag Crash Sensor Module section of the air bag system. Mercury switches are not found in air bag inflation units that are typically found in steering wheels, instrument or dash panels, some seat backs, or in the roof as side curtain air bags.

Warning: The air bag inflation units contain pyrotechnic devices that inflate the air bag during a crash. Removing them requires special training, and they are not part of the ELVS program. Only the Air Bag Crash Sensor Modules should be removed and shipped to the ELVS contractor.

 

General Procedure for Removing Air Bag Crash Sensor Module:

  1. Confirm vehicle is equipped with an Air Bag Deployment System.
  2. Disconnect the battery.
  3. Locate the Air Bag Crash Sensor Module on the vehicle (location varies by vehicle model).
  4. Remove the module. Place the entire assembly in the collection bucket. Do not attempt to remove mercury switch pellets from Air Bag Crash Sensor Modules.
  5. Collect and recycle the modules with care.

The locations where the Air Bag Crash Sensor Modules are commonly found are under the center console on the drive line tunnel, on the floor pan below the driver’s seat, or behind the glove box.
