Crash Sensors

Print

The crash sensors are located in the front of the vehicle on either side of the front radiator support. In the event of a head-on impact (or at least a 3 / 4 frontal impact, the sensing mass inside the sensor breaks away from the bias magnet. The sensor mass rolls along a cylinder toward two electrical contacts, if the deceleration is sufficient, the sensing mass will bridge the contacts and complete the primary deployment circuit to the air bag module.

The mounting and orientation of the sensors is vital to system operation. The sensors should be inspected by a qualified individual after any impact where the sensors could have been damaged. If any structural damage is evident, the area must be repaired to its original condition, otherwise the sensor orientation could be compromised. If the sensor(s) have received damage, they must be replaced.
