Press the power button at the top, and you can slide the lock button.


Both of my previous scanners one goes for 150 dollar  and another one reaches 400 dollars are not able to access to the computer of airbags, so let’s see out of box without any updates and registration of this MaxiDas DS808 scanner can do for you.
As you can see, a red warning SRS light and watch the information sent, and it’s the reason why I need to get back DS808 scanner and find out what is happening to the vehicle.

Here you are, the MaxiDAS DS808 scanner is connected to the OBDII port of vehicle and the ignition is on.

Definitely go for “Automatic selection”

I don’t want to tap the VIN, so I will read it automatically.

And here you are, it is really pretty fast, this is absolutely awesome.
The new generation scan tool is super fast.

I know this OBD II Scanner Tools is 2004, so I will click “From 09/2003 to 12/2007.

Please select the steering left or right, all right , I click “Left”

Confirm vehicle profile, let’s say yes.

Yes “Diagnosis”, so you can see fast it goes.

I’ll go for “Auto scan”
Try to read fault code
No fault codes detected.

But I’m just confusing where is the airbag problem.

So let’s exit to “Diagnostic menu” and select “Control Unit”, and click on “Body” then “AB-airbag” all right. No communication between the tester and control unit.
