Abs Light Issue

[GasHog369]

I did search but none of the topics had my exact issue so...

 

Today on my way home my abs light came on.. After a few miles while driving cautiously it turned off... It did this every now and then on my way to autozone only to find out they dont have a scanner to scan for abs issues. So on my way to my dads friend which owns a shop i noticed it turned off more when i stepped on the gas harder from a stop? But other times it was just on either if i was stopped on going....

 

After turning off the vehicle and turning back on, it would go off one time, but the next it was on.... So from what i gather online , it could be a wheel sensor (which i had both replace earlier this year) or could be the abs module

 

My dads friend is going to scan it tomorrow after i get out of work hopefully but i'm curious if there is anything else i should look for.

 

The kid at autozone told me there is no abs fuse in truck which i am almost certain there is...

 

I feel no difference in the ride / no sounds / and no vibration in pedal.. Just the damn light and the dinging If it is the abs module , hopefully i have the 1 of the 3 that is repairable for this truck... modulemaster.com looks like it can fix it if its the repairable one...

the abs module may be loose or going out...my truck began throwing dic lights for the brakes and it ended up needing an update and reflash at the dealer..

dont guess at this ,it needs to be diag'd properly,

 

you can get a manual to check for fuses but there is nothing u can do except get a shop that has a tech2 scanner and proper diagnoses manual and ABS training,and thats the dealer

I'm going to get it read tomorrow after work as long as i can get there on time.. I was just trying to prepare myself

eh shit happens...then it rolls down hill

[gmtech4]

nothing to prepare bud,

 

but getting it read means nothing,absolutely nothing ,i used to scan customer cars at the dealer for free and clear them, a waste of time and money,made me nuts

 

you need to get it diagnosed PROPERLY or put up with the light as it goes back to regular brakes as long as a code is present

 

listen to a tech

 

change your thinking on what your doing....you're wasting your time Jerry

Could just need a reprogramming. We just fixed a 3500 van with a reprogram. Abs problems suck. If it's not a sensor problem, most of the other components are in the abs module. They are expensive!!!

Got it scanned today and Tech2 confirmed it is a bad sensor in Right front.. One of the ones i allready changed last year... Shop said it could be a loose wire on it as the light goes on and off sometimes.... Taking it in tuesday for them to tear into the hub and see whats up... Thanx for the advice all. i will keep ya posted.

Got my truck back and the light is off!

 

When the shop raised the truck up today they noticed the wheel had a ton of play in it ... Took off the wheel and the wheel bearing fell out! $360 later, It feels like its driving a lot tighter... They asked me if i heard a growl noise while driving , and i responded with "Between the train horns, music , and cherry bomb extreme, It sounded like usual", lol
