Question: ABS and Traction Control light fixes
is there any troubleshooting advice regarding the ABS light and Traction Control light before I spend $85 on a diagnostic?..They both came on while backing out of the garage last weekend..I tried to look things up and this problem seems common in Pontiacs and maybe in GM cars in general..any way I can clean a sensor or maybe a check a fluid level? hate to sound so cheap but spent $70 replaceing turn signal and having brakes cleand and adjusted in DEC..Tires broke me for Jan and Feb ..March was tags and inspection..I just need to catch a break!
Thanks for any advice

You'll want to get eh diagnostic codes read out from the ABS module, then we may be able to give some more info, but without those codes it's pure guessing, which I don't do with other peoples time and money.

Check for a hard bend in the brake hoses going to the front calipers when the wheels are turned hard left or right. They do break down inside. Also when the front tires are removed, you should be able to set the brakes then after releasing them move the rotors slightly back and forth until they bump the studs to make sure the brake is releasing. If not, remove that brake hose and if you can't blow through it, you've found your problem. Roughly said, if the brake fluid can't return when the brakes are released the tight pads keep the wheel from rolling properly and the hub sensors report a slipping condition to the computer while driving and the traction contol is activated and the ABS won't like it because only one sensor is activating the ABS system and it will show a warning to the driver. It's an $18.00 part and an easy fix for shade tree mechanics. Remember to bleed the caliper that the hose goes to after the installation. It's a good idea then to replace both hoses because the other hose could have some restriction too. When all the work is done and all the tires are at proper inflation, I would disconnect the battery for 5 minutes then reconnect it so the computer resets to it's defaults
