That's interesting, so it is pulsing under heavy braking? Is that a common problem? I wonder if either unplugging all the sensors or maybe the module itself would disable it. Just the sensors might freak it out and cause constant abs actuation each startup until it confirms the fault.
Yeah, the ABS "works" as far as I can tell. The wheels don't lock up. It pulses. It's just way too generous towards not locking up the brakes, and doesn't pulse with a high enough frequency, from what I can tell. My vic is lifted for offroading, so it's a real issue stopping on gravel.
I'm thinking pulling a wheel speed sensor would be the easiest, but I haven't looked into it yet.
Might have to pull all 4 or else it'll be 3-wheel braking for the first few miles. I assume the wheels are all the same size? Are the abs wires stained at all with the lift? Might be worth watching them all with a monitor to see if any are acting up. I think Forscan is available directly from their website. It's a pirated copy of Ford's IDS, basically, and I know it was recently pulled from the Google store. It works for ios and windows too and can be connected by usb or bluetooth/wifi obdii dongle.
In the RSX one came lose, and it disabled the entire system, so that's how I assumed it worked in the vic as well, but I guess I'm not sure.
All wires are sustained from when I bought the vehicle, some could've been compromised previously.
I have an OBDII BT scanner, I might check out Forscan, thanks!
