I found some troubleshooting info on modulemaster.com that talks about first verifying that module is receiving power by checking that the 10a fuse in the dash is okay and also 50a fuse under the hood is okay. I found the 10a in drivers side dash area and it was okay, where is the 50a fuse located under the hood, I don't see a fuse box?

The ABS light comes on right after starting vehicle, do not have to move vehicle for light to come on. I have looked at both wheel sensors and cleaned them, doesn't appear to be anything out of the ordinary. The ABS is not working and I don't recall any unusual symptoms before the light came on.

Am I on the right path to finding the problem? Hoping to avoid a trip to the dealer right now as money is tight and don't want to spend the $40-$50 to have them pull the codes. Modulemaster also indicated that they only repair modules from the 99 and up Blazers, is there anyone that repairs the 96's or am I limited to finding a working used one?

Any help is greatly appreciated.

 

Just to add, if you have a multimeter, or can get your hands on one, test those wheel speed sensors. I've seen it where they read correct even with a Tech II on it, and then you hook up the multimeter and it's trash. So I would double check those sensors.

 

Thanks. How exactly do I test the sensors?

Also, do you know were the 50a fuse is under the hood?
