This topic has been covered to death in many threads on here. If you haven't tried everything in those threads search for them now. There is a speed sensor issue with MX83->JZX81 that's documented and well understood.
If you haven't hooked up NCO+- in the first place it suggests a lot is not hooked up properly.
ABS light on suggest you haven't hooked up the ABS gearbox speed sensor.
Please search and read the threads first, then if you still have questions ask.
