If you suspect the EBCM there is a few places that rebuilds them. It is my understanding that there are little jumper wires that are soldered in and they have a problem breaking due to cars vibration etc... Also believe they replace a few know problem components. You can send in your module and they will test, repair better than new, and also retest and clear all codes from computer. You can acutally take your computer off and send in and still continue to drive your car as this only disables ABS, which if you have codes, it's already disabled. Cost for a Bosch 5.4 rebuild $160. A new computer from dealer will cost you around $700 or so. Here is a link if you are interested. They also have an ABS wizard tool thats asks you questions to help diagnose your problem. Good luck
