in my case, i looked around for some info and found out that mostly it is caused by the wiring harness.

so i replaced the harness paying 250.

no! it didnt fix the problem.

So, someone advised me to get the ABS system scanned. and i did.
Rear left ABS malfunction code came up.

i bought the hub for it, and then took the wheel and the caliper off.
then there, the plug not fully in.
i took the plug off, cleaned it, then put it back on.

ta da! no more warning lights.


Tip.
----

when you are having these problems, get abs scanned first to get the code. Dont do anything else like what the mechanic says.

then go from there to save lots of money.

 

Lucky! In my case it's probably the wiring harness.

 

i didnt even use the new hub,
i returned it and got the refund.

 

Great job on the detective work

Glad it was an easy fix for you

 

Good to know...... Thanks,

 

Great job!

This is why I am constantly telling people to check (and double check) the wiring harnesses (no matter what component) prior to running out and buying the part. Kudos on your diagnostics.
