so cruising down a local road during heavy rain, I hit a water patch with my track tires while braking and locked up my wheels. I lost all traction and started sliding sideways then round and round. luckily nobody was around and nothing happened to the car.
then it occurred to me, wtf happened to my ABS? I then did some trial run at a large parking lot when it was dry and sure enough, I have no ABS. All 4 tires lock up and I don't feel any ABS modulation at the brake pedal. I checked all the wires: IGN 12+ wire, brake 12+ signal, two ground, and two constant 12V from alternator are all reading correct voltage at the ABS harness end. my speedometer is working correctly, so I must assume the ECU wires and all 4 wheel speed sensors must be fine.
I should mention this is a used rx8 ABS pump from ebay which I relocated to the front of the car for various reasons. My original one was damaged. Do I have to do anything to the ABS pump and module from another rx8 to make it work appropriately after install? from my understanding, the functions of the ABS pump is completely controlled by the ABS module attached to the ABS motor, and it receives no input from the ECU. It just has 2 wire output to the ECU which as I understand are for speedometer. I have no DSC.
any thoughts? thanks all.
