Airbag sensors usually are located at the front of most of today’s American made automobiles. They are placed purposefully in the known impact zones of a vehicle. This way when a crash occurs, the sensors can signal the airbag to deploy nearly instantaneously.

How does a crash sensor work?

Crash sensors need to detect a collision and convert it to usable signals within milliseconds. The sensors measure this acceleration and relay it to the control unit as usable data. Many of our cars are fitted with ultra-fast pressure sensors in the front doors.

Can you test a crash sensor?

Testing of an airbag sensor is possible, but should not be done. The only way you safely should test an airbag sensor is to use an automotive diagnostic tool to read the airbag control unit’s trouble codes and live data.

What is the resistance of a crash sensor?

Resistance should be less than 2 ohms. Locate and repair any open circuits found in #617 or #624. If resistance is greater than 2 ohms, replace entire right front impact sensor. Clear diagnostic codes and test drive vehicle to see if codes return.

Can a dealer reset air bag module?

After you receive the module back from us you will not have to take it to the dealership for any additional programming. All airbag control modules can be reset and reprogrammed, with the exception of flood, fire or hardware damage.

The area of accident damage is defined as the portion of the vehicle which is crushed, bent, or damaged due to a collision. Do not try to determine whether the impact sensor is undamaged, replace the impact sensor.

Can crash sensors be reused?

It all depends on the severity of the accident. However, in most cases, the front impact sensors are reusable unless they have been physically damaged or the wire leading to it has been crimped by metal. However, in most cases, the impact sensors can be reused.
