2nd Gen ABS issue

I'm a little baffled with this one. I have no codes that are on my dash or that come up in my scanner at work. however when normal driving conditions my abs system activates every time I bake rather fast or slow speeds.. I have inspected my speed sensors and all seem to be In good shape with no damage to the sensor or the wiring itself. any pointers to check or where to go next would be much appreciated thanks.

 

I suspect you have one or more wheel speed sensors dropping out at low speeds, possibly due to rust-jacking if you live in the salt belt.

Do you have a scan tool that can read ABS data?

 

Ditto. Know my cheapo Bosch scanner came up empty. Took to shop, plain ol Firestone Auto Care, and their scan tool came back with codes relating to abs speed sensor and wiring.

 

Yup, its self clearing once the signal corrects as you drive.

Low speed is hard for ABS to manage with poor signal, but its designed to self clear so you retain it at speeds that matter.

Need a scan tool capable of ABS and an inspection of the signal. It's not always just a sensor.

 

Ill have to take a more indepth look at the scanner at work in the abs system. I do live in salt lake and the rust corrosion is real lol I'll report back with findings. thanks

 

I'd graph all 4 speed sensors and see if one is dropping to 0 before the others, if so focus on that one.
