I read that my ABS light is coming on because ABS pump is not getting a "wheel turning" signal from one of the wheel sensors. How would I go about finding out which of the 4 sensors is bad?

 

First thing I woudl do is to check to make sure they are all there and in the correct position.

 

You can find it out by shorting a service connector. Then your ABS light will blink out the code.

 

how would I go about doing that? thanks for your time.

 

you have 2 pin connector behind the radio (blue one). Short it with paperclip and switch the ignition. ABS lapm will blink out the code.

 

anybody know what the other connector is for? I know the blue one is for CELs, how about the other?

this 5 pin one?
it's for a diagnostic computer (PGMFI tester or HDS- Honda Diagnostic System)

 

do I have to remove the radio to get to it?

No, you don't. You can reach it just behind the radio from the pedals area.

 

first thing i would do is check all the wheel sensors and
make sure they're intact.

 

Checking the code saves the efforts Checking wheel sensors sucks

 

once you get the code, where is the reference key? thanks

In helms Tell me your code, I'll tell you what to fix

 

Whats up man. I got 3 blinks about 5 seconds apart when I shorted the connector.

What code is that? Thanks for your time man.

By the way. Could you send me your e-mail address. I think my membership here has a time limit. quazar2k@hotmail.com

Thanks again, I really appriciate the help.

 

I have the same question you do quazar. I have been trying to figure out how to access and work the diagnostic socket terminals as my ABS light on by Gen 4 lude is on. Pentaq showed me this post. I found this sheet on the web that gives the codes for Accord Prelud Legend and Concerto.

Below it the site

Here is a copy of what is on that site hope this helps.

By the way, was it easy for you to get behind the radio and test it? I am going to try tomorrow

Honda ALB2 ABS computer - fault codes.
Fault codes: how to access. Turn igniton off. Bridge diagnostic socket terminals. Turn ignition on. If ecu is ok warning should come on for 2 seconds and then go out for 2 seconds. The lamp should then begin to flash. The first set of short flashes indicate the first number of the fault code. A brief pause seperates each flash. A medium pause seperates each group of flashes. If there are more than one code stored a long pause seperates each trouble code.

Code
Fault

1 Hydraulic pump motor over-run (contact BBA)

1-2 Hydraulic pump motor (contact BBA)

1-3 High pressure leak (possibly modulator)

1-4 Pressure switch (contact BBA)

1-8 Pressure accumulator

2-1 Handbrake warning lamp switch circuit faulty

3-1 Right hand front rotor damage

3-2 Left hand front rotor damage

3-4 Right hand rear rotor damage

3-8 Left hand rear rotor damage

3-12 Different tyre sizes fitted

4-1 Right hand front wheel sensor

4-2 Left hand front wheel sensor

4-4 Right hand rear wheel sensor

4-8 Left hand rear wheel sensor

5-4 Right hand rear wheel lock

5-8 Left hand rear wheel lock

6-1 Front fail safe relay

6-4 Rear fail safe relay

7-1 Right hand front modulator solenoid valve

7-2 Left hand front modulator solenoid valve

8-1 ABS operation fault

8-2 Electronic control unit (ECU) fault

8-4 Electronic control unit (ECU) - internal circuit fault

 

what code is that though? The 3 blinks 5 seconds apart? is it 1? or 3-1? I am not sure how to translate.
