Have Can Bus error U0073 In checking resistance and voltage at 9 Pin diagnostic connector the first problem that appears is I only have 3.6V at PIN B instead of 12V. This is EOKO voltage but cannot find a wiring diagram to see where Pin B is fed from. A blown fuse or other open would have zero volts. Has anyone seen this before?
