When you say ABS computers Ross, are you referring to PCM's, or is there a separate unit? Also, just for shits n giggles, do you think it might be ties into the ECU?Torontofirecaptain said:It is not as easy as it sounds.
You need to add the following:
ABS pump & control module
Master cylinder & brake lines to pump (yes they are different)
wiring to both front and rear wheels (easiest ways is a full body harness, but stringing wiring will work) No wiring is in the SXT for ABS.
all four wheel hubs need to be changed to ABS tone wheel equiped ones
4 pick up sensors added
Wiring for the pump and the ABS computer needs to be added to the main power junction box under the hood, along with the appropriate 30 amp fuses.
You should, by rights, get the ABS harness from a donor car, since the plug that goes into the computer is unique to it, and nothing else will work. You would then get all of the necessary wiring for the above, at least for under the hood.
PCI bus wire needs to be added to the BCM.
Then, the system needs to be primary bled, then it needs to be put on the Scan tool in order to cycle the ABSW pump & computer to bleed the system.
Then, it still may not work.
I have done all of the above, and still the system refuses to properly operate. My local dealer is as stumped as I am, he has run diagnostics and it show to be functional at times and "no PCI bus" at others.
I have tried 3 different ABS computers, and they all work in my "m", so I know it isn't that.
When I get time, I wil be installing a BCM from an ABS car to see if that will cure the problem, though the dealer didn't seem to think it would.
My advice, unless you have plenty of money, time, skill and patience, don't bother.
The ABS has a separate "brain" that is mounted on the ABS pump. It controls the valving, based on the signals it receives from the wheel sensors and the BCM.LOUD98ES said:When you say ABS computers Ross, are you referring to PCM's, or is there a separate unit?

It's really not worth it. Money would probably be better spent on better tires and brake pads.
