John: That portion of the test is for the idle switch. This tells the ECU whether the throttle is opened or closed. What is confusing here, is that the wiring schematic shows 12 volts going to the switch while the testing procedure in the FSM shows 4 volts or higher as ok. finish with the complete tests and let me know results.
Thanks
