ABS and Servic Brake System light

[john2115]

i changed my tire size to 35 and then to 34.5 hoping it would help and my lights are still on and im getting kinda annoyed. I also scanned for trouble codes and it says i have none except my lights are on the dash an ABS and SERVICE BRAKE SYSTEM. Is my tuner not working right or what? I have no way of getting these taken off and the ding noise is driving me nuts.

[john2115]

Is there a fix for this? Its been like this for about a month and ive had my intune for about 3 weeks i assumed my intune would get rid of these codes but it didnt. The intune is telling me there are no trouble codes but there must be since i have lights on the dash, this past weekend i checked every abs and brake line i could fine for a tear or over extension from the lift but came up empty handed. The last thing i could try is buying new wheel speed sensors which is gonna be alot of $ and time and i have neither. I just want these codes at least read so i could figure out where to start. please help!

this is a random issue on some 07 trucks for some reason, we are still investigating.

Thanks

[john2115]

yeah i heard about that issue with the 07's but mines is an 05 duramax.

[mikel]

so, were you having the ABS lights prior to using the tuner?

[john2115]

yes and i ran the DTC scanner to see what the codes were but it said that i have no codes but yet they are clearly on my dash.

[mikel]

ABS codes are not something that will generally come up with a code reader, you may need a specialized tool or a techII to see whats causing them.

wish i would have known that before i spent 400 dollars on it.

I apologize, but its not something we ever advertised, or lead anyone to believe it would do.

You are welcome to come here and ask us anything you need to know prior to a purchase...

Thanks

its not yall's fault just irritating me with these lights. I just assumed all lights on the dash can be solved with a DTC scanner.

Question- Does anyone have an 07 that does not do this?

please note that the OP had ABS lights/issues before he ever bought the tuner.

Mikel, you probably remeber me having this same issue, is there any thing you can suggest for me?

[randyc]

Mikel, Yes I noticed that..........................In my case no, only started after the tune.
I asked the question to see if anyone with an 07 is NOT having the problem to see if we can figure what the problem is by comparing differences. I have a theory that maybe because my truck is close to a brake job (pads are not yet squecking, but getting short), that this might be the problem.

y understanding is it has something to do with a 3 channel ABS system vs a 5 channel ABS system, still investigating.
