Broken ABS Module pin

[Bimmer man24]

Okay, so I tried to check the sensors but I couldn’t get my leads down the tube since the pins are too far down I tried alligator clips but there’s not enough space anyone have any good ways to test it. For some odd reason the front passenger brakes doesn’t have a brake sensor at all it’s completely gone but yeah I forgot there is a “check brake lining” that comes on in the little dash screen. I checked the fluid and it is right at the minimum so Im probably just going to do a flush on the fluid since it’s black. Also my car has its own parking brake light. I was looking at the fox well scanner the nt301 would it be able to do everything a very expensive diagnostic tool can. Any if anyone has any good recommendations for the best diagnostic tool for under $100 that would be appreciated.

And what did you mean by telephone splice?

NT-510 is the most basic scanner that is useful.

There are only brake pad sensors on left front and right rear wheels

This is what a phone connector looks like.

You can use a short piece of 24ga wire to jumper around the main connector and two of these butt splices.

Oh wow I didn’t know that btw I tested the female wheel speed sensor because it was easy to test but I only got like 0.020 volts and no resistance on any of the sensors wheel and brake

You can pull the brake pad sensor off the back of the brake pad to see if it's worn. Often people will swap a worn sensor onto new pads or the pad is worn out.

If the pad and sensor was replaced, you still need to reset the system.

Meausured Ω across the sensor should read open not shorted.

I’m guessing I need a diagnostic tool to reset it. I meant to say it was OL does that mean it’s functioning correctly?

[andrewwynn]

Nope. To reset you need the key that's it.

OL means worn out should read shorted. Are the pads worn out?

You can strip the end of the wire and twist together to test the system but if the pads are worn they need to be replaced.

When the sensor is replaced, to reset you simply turn the ignition on without starting and wait a full minute.
