ABS COMPUTER is located right next to the ECU. An inch to the left. I jpg'd a locator map on a post that was called something like *I CAN'T FIND MY ECU*. That thread has a photo of the ABS also. Can't be more than twenty or thirty threads down from this one.

 

local mazda dealer might have a tester, if not they should be able to bring one in. it'll plug in and give you the code telling you whats wrong. I think you would need a scope to do any testing yourself. (watching freq. in the wires, not voltage)

 

I just breezed thru the 89 manual online at http://FC3S.ORG and I saw in the BRAKE section some checks you could do with a mm. I have no ABS.
