ABS/Airbag reset tool

[N2MYE30]

So I have a buddy of mine that has a couple of cool tools.

He just bought this...a ABS/Airbag reset tool. Great, now I can reset my SRS light, right? So I hooked it up to my coupe.

This is what I used. The Autel AA101 ABS/Airbag scanner.


So I plugged it in and I am getting error on the screen that reads...
Communication tester not communicating with control unit.

Its brand new so it should be updated. So I wanted to see if it was the connectors so I plugged in the Snapon Modis...

It worked! This thing is cool! Its amazing what can be read and controlled pre-OBDII.

So, the question is, anybody else use this tool to sync up with an e30?

Awful cell pic in action...

Really, no one has used this thing?

Modis is a great tool, nearly affordable to the normal DIY guy.

I need to reset my ABS light to see if it will go away. Are you sure that a device such as this works to reset the ABS light as well? That would be great!

Your ABS relay is probably toast from someone not jump starting the car correctly.

To the best of my knowledge there isn't a reset for the ABS. But it isn't difficult to trouble shoot.

Troubleshooting the ABS system isn't very difficult. It is a stand alone
system that ony gets input data from the brake light switch, wheel sensors and
system power. The parts of the system are the ABS module located next to the
steering column, the ABS relay mounted above the ABS module, the ABS unit in
the left front of the engine bay, and a wheel speed sensor at each wheel.

If the ABS light comes on with ignition, but doesn't go out when the engine
starts, a wiring problem, bad module, or bad ABS relay are the likely
candidates. A failed or weak alternator will also cause this because the
system voltage won't rise enough. There is a fusible link inside the ABS relay
that can be blown. The relay can be repaired, or better yet replaced.

If the ABS light comes on when you turn on the ignition, goes out when the
engine starts, and then comes back on before the car is moving the cause could
be a bad module, a bad ABS unit, or a wiring fault.

If the goes out after engine start and only comes one when the car is moving,
there's a problem with one (or more) of the sensors. The simple test to find
out which sensor(s) is the cause is to disconnect all but one of the sensors
and drive the car. If the light comes on, that sensor is sending a speed
signal to the ABS and is good. Repeat with each other sensor to find the
one(s) that don't cause the light to come on. Since the ABS module has no
speed input besides the wheel sensors, if only a bad sensor is connected the
module can't tell the car is moving and thus doesn't fault on missing speed
signals from the other wheels. Once a bad speed sensor is found, if a new
sensor still doesn't work, there could be a wriing fault in that circuit or a
bad input channel in the ABS unit.

But nothing on the SRS reset?
