the controller he makes is a replacement for the stock DCCD controller mainly for people using a DCCD equipped transmission in a vehicle that didn't come with one. The problem being that the stock DCCD controller talks to the ECU the ABS and has special sensors such as pitch/yaw and steering input, that non DCCD equipped vehicles lack making the DCCD either useless or with a little wiring a full manual controlled lockup. What the DCCD pro controller does is allow for swapped cars to have an automatic (and manual) control over their DCCD lock up.
So what he's saying is that if your 6mt was swapped in and your DCCD works, most likely your using one of his controllers, because to swap everything necessary and do all the wiring would be an overly complicated and unnecessary undertaking.
If you are using a DCCD pro controller, then the ABS status of the car is irrelevant, it uses input from the TPS, e-brake switch, and a gyro (provided with the unit). Unlike the stock controller which without a functioning ABS unit will not work properly.
What vehicle is this, and is the 6MT a swap, and from what?? what is the deal with the axles you are referring to? how are they wrong? I have a feeling that DCCDPro is right, and that your ABS light is on because your axles have the wrong "tones" (gear looking thing at the end of the CV joint which allows your ABS wheel sensors to tell how fast each wheel is turning) and is causing your ABS unit to throw a trouble code, which is causing the DCCD to not allow full functionality.
