Magotan airbag crash sensor failure induce lamp is lit

With a mileage of about 80,000 km of FAW-Volkswagen Magotan multi cardiag m8sedan. The vehicle while in the procedure of going the airbag lamp is lit.

Failure examine: Motor detector detects the airbag manage unit suppliers the fault code 01221 (the aspect of the driver's side airbag crash sensor) and 01222 (the facet of the front passenger aspect airbag crash sensors); engines detector obvious fault codes, start out only apparent fault codes 01221, reconnect immediately after disconnecting the battery terminal, very clear the fault code 01222. 3-4 km after the street take a look at, moving inside of a straight line, the airbag light on the instrument re-lit,NEXIQ 125032 fault memory once again saved fault codes. Specifically throughout the crash sensor wiring to your regulate device; fault is not really excluded; swap the airbag management device, the fault persists, indicating a fault inside the crash sensor.

Troubleshooting: Replacing the side with the entrance passenger side airbag crash sensors, road test, troubleshooting.

Failure Investigation: In accordance into the preliminary examination with the circuit diagram might be excluded with the wiring harness and management unit failure; facet on the driver's side airbag crash sensor, the aspect on the entrance passenger side airbag crash sensor are detected. That is certainly: When the appropriate aspect from the collision, the driver's side facet airbag crash sensor, entrance passenger side airbag crash sensor simultaneously to obtain the right-to-left collision signal; If just one crash sensor collision signal, the opposite aspect does not XVCI alerts, like the side of your entrance passenger-side airbag collision sensor detects a collision, but left with no a collision is detected signal, the airbag management device can not decide which sensor fault can thus only be provided at the same time, i.e. Airbag lamp lighting , must be construed as "signal just isn't responsible."
