abs light and tracton control light

[dkhummerh2]

My abs light and traction control light came on yesterday while I was setting there ideling and now it is on all the time. If just snowed here so I didn't know if something was messing with it or if something is wrong. My buddy has a shop and can check the computer but that won't be until this weekend. Just wondering if anyone else has had a similar issue.
thanks

Check with Humtech he knows his way around the Hummer big time.

You can check wheel speed sensors for any moisture in them which can cause issues. Other than that I would pretty much need a code to point you in the right direction.

I have all kind of issues like that, it happens every now and then but mine started after I installed the ultimate ipod adapter(nucleus) just my 2 cents!:notallthere:

[dkhummerh2]

My buddy will bring up the code this weekend. I thought bout disconnecting the battery and letting everything reset. Do you think this would work. I just don['t want to do it if not, because I will lose all of the data in my head unit
thanks

Another question. I replaced the power steering pump last month. It kindof sounds like its whining more than usual. If i got a bum pump, could this do that>
thanks

The pump should not cause any issues, the brake system just uses the power steering pump for brake assist. Better off not disconnecting the battery if you can get someone to read the codes for you. If the fault is not current the code wont reset and you will have to wait till it fails again to retrieve a code. Better off finding the fault and fixing it in my opinion. Some people dont feel this way, hell I have cleared codes out of my truck just cause I didnt want to fix it but i have my own scan tool for my laptop that i take with me on any roadtrip and can usually take care of any problems on the road as long as i have the parts or access to them.

dkIf you have Stock head unit, only loss will be clock time.

Mine is aftermarket.

the snap on computer can't bring up a code. any ideas?

[HUMTECH]

You need to find a scan tool that can read chassis codes, any scanner that has gm enhanced capabilities in it. Or go talk real nice to a local gm tech and maybe he may scan it for you. I have done this for customers before.

how'd you figure out which one was bad? Sorry for all the questions

[splne1]

Had the wife sit in the truck while i messed with the sensor wiring to each hub then when I found the culprit on the passenger side i removed the tire and discovered it had a severe gash. Then just remove the caliper, brakes, and disk and use an allen wrench to remove old sensor. Plug in new one and verify light goes out!!! Re-install and enjoy!!

I am having this same issue. Did the abs sensor replacement work?
