2010 nqr, getting a turbocharger boost control solenoid control circuit code,, I replaced the boost controller module, actually tried 2 new ones, I have pinned out the harness, loaded the wires as well as continuity, tried a actuator, went to the junkyard and got an ECM, tried that, Isuzu wiring diagram says there should be a 5 volt reference wire coming out of the controller module, mine all test 9+ volts with 12.5 volts of ignition power coming into the module
