Finding a fault code for ABS Brakes

what ISuzu in what body. KB? backie>? in what country>?
first off the brakes must be good for ABS to work
so we inspect brakes or
or we use a real ABS scanner, the PCM scan tools do not scan ABS, (in most cases) so you need to use the correct tool.
The ABS tool will in fact show a code. for sure.
sounds like your Isuzu shop is incompetent to me.

are you tell us that you took the car to Isuzu and the ABS light was off?
well if that is true then , it can be impossible to fix.
after all , you cant fix that which is NOW working.

if that is true,. only scanning the ABS failed works.
see?
or if lucky the brakes just need service.
(pads bad)
stuck caliper pistons. (hanging up, hot)
caliper guides stuck, (same reason)
air in the system, seems not.

ask the mech to drive car for day with a real ABS scanner in the car, and when it fails , scan the ABS.
or buy one your self and do that.
or if rich replace parts 1 by 1 in the blind hope of finding which part is intermediate. $$$$$$$$

scan the ABS not the PCM the PCM only knows ABS is failing.
scan the ABS to see all ABS codes.
and do so , only with ABS lamp glowing.

Abs detects each wheel of the rotation.i will check from the tire then monitor with the scanner to see the abs sensor on each wheel and chk any fault code as well.anyone of the abs sensor have not detect correctly,it will be not working right.that's the basic of ABS.good luck

the abs light is on, it telling you that there have a problem on your abs system, such as simple wiring issue with a sensor, or it could be as bad as an abs module. it need to be plugged into a OBD2 code scanner/reader to know exactly what part triggered the code.

Finding the fault code will not clear the problem if you reset the system without finding the cause the light will just come on again or the fault code will not clear.
Anything related to brakes should be checked out by a garage/mechanic and not ignored.
Its probably just an abs sensor failed but its better to be safe than sorry.
Sorry for the lecture but I wouldnt like to see anyone hurt due to brake system failure.

As what you say I try my best to find the most suitable diagnostic code reader for you, and not only the function is perfect but also the price is reasonable, it is ADS-1S .

ADS-1S is a Full-line vehicles fault diagnostic scanner system, which is based on pc desktop and laptop platform. It can test cars manufactured in Asia, America and Europe countries. It supports all kinds of vehicle communication modes. To learn more:

The ABS light has nothing to do with the condition of the brakes. The ABS is is own system that relies on the braking system in order to function. If the ABS light is on there there is a fault in the ABS system. This will also turn off the traction control since the traction control uses the ABS system.

The best start is to have the ABS system scanned for trouble codes. This will give you a clear direction in which to start finding a solution. This will need to be done with either an ABS specific scan tool or a high end multi-function scan tool. You can also try your local auto parts store to see if they can do this for you.

Once you know what the codes are than you can start figuring out what to do to fix it.

Some common failures on these are bad wheel/hub bearings, bad speed sensors, broken speed sensor wiring harnes.

Post the codes and I'll be happy to help you further.

If the ABS light is coming on it has fault codes set. Are you sure that you are using the correct scanner? Are you sure you are scanning the correct connector? You MUST use a Ford Superstar II scanner or a scanner that can emulate Superstar II functions. The manufacturer does not offer any other method for retrieving codes on this system. The connector for the antilock system is located on the right radiator support under the right headlamp access cover.

No that is not normal. When the ABS light comes on and stays on you have a fault present in the ABS system and the ABS control module is alerting you to this problem. As long as the light is on the ABS brake system us disabled and you have in effect standard non ABS brakes. In order to find out what the fault is the ABS system must be tested by using a scanner, it will have a code in memory.

You must hook up a scanner that can read the ABS system to the diagnostic connector under the dash and see what faults codes are present in memory.

What this means is that the abs module is seeing a problem in the abs system.This has nothing to do with the regular brakes.What you need to do is get the codes from the abs module and this will help in finding what could be causing the light to come on.When the abs light comes on the regular brakes will work normally but your abs brakes will be disabled.Let me know what codes you find and I can help or explain what the cause could be.Good luck.
