ALB checker or ABS checker wanted

[nomac]

Anyone in Australia with a ALB checker or ABS checker to check the ALB ABS on a 1991 NSX.
Thanks

There is a trick how to test the ALB sensors feed's towards the computer with a multimeter,
I'd need to look up how it exactly goes, I must have it written down some where.

adnan .... you're everywhere!

Many thanks. Will this yield the codes listed in the factory manual?

Sorry for the late reply,
First of all do a service loop jump like you'd read out CEL codes from the engine,
You'll trigger the ALB light to morse code you the signals

Comes on and remains on while running:
1. Stop the engine.
2. Turn the ignition switch on and make sure that the anti-lock brake system indicator light comes on.
3. Restart the engine and check the anti-lock brake system indicator light.
There is no problem in the anti-lock brake system, if the anti-lock brake system indicator light goes off.
Go to step 4, if the anti-lock brake system indicator light remains on.
4. Stop the engine.
5. Disconnect the service check connector from the connector cover located under the glove box.
Connect the two terminals of the service check connector with a jumper wire.
6. Turn the ignition switch on, but do not start the engine.
7. Record the blinking frequency of the anti-lock brake system indicator light.
The blinking frequency indicates the problem code.

If you need help with counting these or translating the code let me know I'll mail you the chart.

The anti-lock brake system indicator light remains ON after the engine is started, however the antilock brake system indicator light does not blink
any
code or sub-code. Check the following items:

Loose or poor connection of the wire harness at
the control unit.

Faulty ALB 2,3 (No. 32) fuse.
Open circuit in WHT/BLK wire between ALB 2,3 (No. 32) fuse and control unit.
Open circuit in YEL/BLK wire between fuse No. 4 (1 5 A) and control unit.
Short circuit in BLU/WHT wire between gauge assembly and control unit.
Open circuit in WHT/BLU wire between alternator and control unit.

Now there is also a rather time consuming method of check sensors with the multimeter attaching that to the main ABS control unit.
I can e-mail you those instructions they are rather lengthy, Don't have the time to upload pictures and type out the whole explanation.

Gday Nomac, would you be able to put up the codes and trouble shooting info somewhere so it may benefit others in the future?

once i have the spare time i can try in organize that information and put it on the forums, just don't have the time at the moment.

That would be fantastic. Hope I don't have to use the info for a while though.
