Many people said that their bmw airbag light on after some changing:
- Replacing the seat occupancy sensor.
- Replacing the steering whell buttons.
- Removal/replacement of the driver’s door airbag.
- Any other changing…
Now i share a simple method to reset BMW E46 airbag light by yourself.It just costs you $20,else if you go to dealer spent more than $100.
Tools you need:
BMW INPA K+DCAN USB Interface $15.99 free shipping
BMW 20 Pin to OBD2 16 Pin Connector $5 free shipping
(If your car is after 2000 and with an OBD2 16 pin port, you can even save this $5!)
INPA software (Come with INPA cable)
Step1:Connect this BMW INPA K+DCAN USB Interface with your laptop USB port and the DLC Diagnostic Link Connector port.
(Since my E46 is before 2000 without the OBD2 port and the DLC port is a round 20 pin connector while INPA cable has only 16 pin connector, so I need a 20 pin to 16 pin connector.)
The DLC port location on BMW E46:
Step2: Install and run INPA software on WIN XP. Turn on the ignition and click the “F2” button. And choose “Body” section then “Airbag”.
Step3: Go to the Error Memory: click the “F4” button.
Go to clear error memory: click the “F2” button.
Error was cleared successfully!
Note: If you reset airbag light,but it immediately or a spell of time come back on, there must be another issues on your car.
