Tips of the B800 srs airbag scan/reset tool for bmw

The BMW B800 airbag reset tool allows you to read, diagnose and clear your car's airbag fault codes. It is a very simple tool that's so easy to use and it comes with instructions manual to help you diagnose problems. The tool is able to display B800 Airbag fault codes and tell you where the problem could be, clears the airbag trouble codes, resets the SRS (supplemental restraint system) light, and it is compatible with most of the BMWs built between 1994 and 2003. The airbag’s SRS light illuminates on the vehicle’s instrument panel normally only after the car has been involved in an accident and the airbag has deployed.

The B800 airbag reset tool in your car is an important safety device, and its module is designed to ensure that it is functioning properly. If the module fails to function properly, your airbag may possibly not be able to deploy during a crash.

Whenever an explosion occurs in a B800 airbag, light is turned on and both the airbag and the controller ought to be replaced. Even after a small accident, the airbag sensor will write in internal memory a special error message “computer fault” or “crash data stored”, after which you need to exchange the very sensor to a new one.

However, with the B800 airbag tool, the software can still be automatically restored under the conditions that there’s no damage to the controller’s hardware and you’ll only be required to replace the airbag only; the controller can still be used again. You can use the tool to repair and reset the airbag computer in your office in one minute without necessarily removing the sensor from the car.

These B800 airbags can also use CAN bus. There are cases when their “crash erase” works only on the table. Should you be defeated to erase the crash data by OBD2 connector, try to disconnect the instrument cluster blue connector and erase by OBD2 again. Sometimes the red diode may appear, indicating a crash data erase error, if this happens, simply remove the airbag sensor from the car and connect it directly to the table and the erasing will be OK.

In some rare occasions the B800 airbag reset system may fail to clear the warning light or reset the service mileage at the very first instant. This is usually caused by the failure of the reset tool to get feedback from the ECU over whether the operation was successful or not. In such a situation the tool will simply send instructions to the ECU to reset, but once the operation is finished it will display “RESET OK!” without acknowledgement from the ECU.

After all the necessary repairs have been successfully performed, you can reset the airbag light by yourself by use of a handheld computerized tool purchased from an auto parts retailer.
