Hi, i have replaced my ABS globe in the dash on my 380 SEC and it remains on. The ABS does not work as tyres lock up under heavy braking. My question is, do the sensors on the caliper need replacing or does the pump and then maybe computer module? Or is there one particular item that always goes and is very common.

Example, I thought I did a fuel pump shortly after I bought the SEC as my Holden GM Commodore did many of these, but found out that theSEC rarely ornever does a fuel pump, only fuel pump relays.

Like this situation, is there something that always goes first in the ABS system that I should change?
Thanks in advance.

 

I have been and cleaned both sensors and light remains on.

 

I FIXED IT !!! There is an ABS over protection relay in the fuse box next to the brake booster (RHD models). It is silver with a 10amp blade fuse on top. The fuse had blown. Put in a new fuse and TAH DAH!! ABS works.

As I wrote above, I cleaned the sensors and then I checked this fuse and there was my problem.
