sacabon

93 rx7..I recently fully removed the stock ecu/wiring harness and added a Haltech ecu..My issue is the ABS light is on and about 30 percent of the time when I hit the brakes to slow down the ABS kicks in and "pulses" like the wheels are locked up from water, ice, snow. The issue didn't show up immediately.. For the time being the abs is disconnected but I really want to solve this issue...Hell it could be as simple as a bad ground or voltage non existent..yes I have the factory manual and i'm able to troubleshoot electrical issues. I don't have the device used to connect to the ABS ecu. Is there a way to pull the codes another way? And YES i've searched the archives with no success. Seems like most people that have abs issues is where the system simply doesn't work. Anyways...any info would be appreciated
