Ok I don't find any wires that are brocken and the ones I checked over like 5 times are the tan/black and org/black from the PCM to the EBTCM as the trouble I am haveing is a code P1573 PCM/EBTCM cearel data curcit. I used a TECH II and under the regular DTC it comes up with this but when you go into the ABS and TCS under chassis it dose not have any codes. When I checked the ABS and TCS it does however show Torque requested at +7 N-m and torque delivered to be -100 N-m. I was told this is wrong but I also dont know what this means. What is happing is at around 88mph my traction control appears to activate itself and I loose about half my boost. This also happens with the TCS turned off. Is the EBCM bad? I dont realy have the $716 the dealership what for it to do trial and eror fixing.
