Howdy folks,
I did a swap from a 2.0 AT AZG to a VR6 MT BDF in a 03' wagon it drives and runs around town decently but am having one glaring issue keeping me from driving it more... I cannot log or communicate with the ECU. Diving into the wiring schematics, confirmed everything from the 2.0 and VR6 are the same in the wires car side. VCDS CAN line and K line check both show green and good to go. Measuring voltage at the back of the IC, the green T32a at pin 5 (W-LINE from ECU) shows battery voltage 12.1v, across the diagnostic module the voltage jumps between 1.5 and 1.6v, and ends up at Pin 7 (K-LINE) on the DLC with 3.3v Key off to 8.8v Key on. Are these voltages correct? Im assuming with communications there's always going to be some voltage at all times. One thing that I have been trying to confirm was if the BDF did engine diag over CAN or K line compared to the AZG that was in there before. Any input would be appreciated, thanks y'all.
Mike
