Hi, i have a 1993 trans am and it has had an abs inop light on for about a couple of months. Before the abs inop light would turn off and on once in a while but it seems to have gotten much worse over time. I bought a Chinese tech 2 scan tool and scaned for codes on the abs system. I had no codes come up at all. The scan tool shows that the speed sensors on the car are accurate since each sensor reads the exact same speed as my speedometer is reading. I cleaned each sensor and put dye electric grease in them and cleaned the sensors with some electric cleaner. I did switch my entire car to LEDs on the exterior besides the blinkers in the front. I have had a couple issues of using LEDs as the car wants to check for a certain voltage and since the LEDs produce less power and volts than the incandescent bulbs do it sets dash lights off. I havnt tried putting back incandecent bulbs in the 3rd tail light but i will soon because it may think the tail light is out because im using LEDs in the 3rd tail light (even tho it isnt burnt out). Also, the abs inop light turns on for 3 seconds and off like normal when i turn on the car but not start it. And i can flash the light and manualy turn it on too with the tech 2. What is interesting is when i look at the abs system in the tech 2 while driving, it says the abs inop light isnt even on!!! I have read just about every forum there is on the abs inop light and am out if ideas. Lastly, the cuise control stopped working when the abs light is on. Not sure if thats tied into the abs system or not. Any help would be appreciated as the struggles are real here lol.
