Airbag Sensor

The airbag sensor is the input device of control signal in the SRS system.
When the vehicle happens to collides, the airbag sensor detects the
intensity signal of the vehicle collision, and inputs the signal into the
airbag computer. The airbag computer determines whether to detonate the
inflatable element to inflate the airbag according to the signal of the
airbag crash sensor.

How To Test airbag front sensor?

1) Symptoms of airbag system failure are difficult to diagnose, so
diagnostic codes are the most important source of information for
troubleshooting. Always check the diagnostic codes before disconnecting the
battery.

2) Disconnect the ignition switch during inspection. If the vehicle allows
to remove the negative electrode of the battery, it is better to disconnect
the power supply. It should be started after removing the negative electrode
for 90s or longer. Because the airbag system is equipped with a backup power
supply, the airbag may still deploy within 90 seconds after removing the
negative terminal of the battery.

3) Even if only a minor collision occurs and the airbags are not deployed,
the front airbag pressure sensor and steering wheel cushion should be
checked.

4) Do not expose the front airbag impact sensor, center airbag sensor
assembly and steering wheel pad directly to hot air and flames.

5) When testing the circuit, a high-impedance multimeter should be used for
measurement.

6) The parts of the airbag are attached with instruction labels, and the
listed precautions should be strictly followed during operation.

7) After pulling out the airbag wiring plug, use a small copper wire to
short the airbag connector.

8) Do not measure the resistance of the detonator tube of the airbag
inflation element, so as not to cause the airbag system to explode by
mistake. The method of decomposing the inspection parts should be adopted
first, and then searching step by step.

9) The airbag system is a very sensitive device. A little carelessness
during inspection may detonate the airbag and cause unnecessary losses.

10)The wire harness and connector of the airbag system are generally covered
with a special color sleeve, which is different from other system wire
harnesses. Do not damage these bushings during inspection.
