EC-78 < ECU DIAGNOSIS INFORMATION > [VQ35DE] ECM *1: Accelerator pedal position sensor 2 signal and throttle position sensor 2 signal are converted by ECM inter- nally. Thus, they differ from ECM terminals voltage signal. *2: Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to *3: The item is indicated, but not used. TERMINAL LAYOUT PHYSICAL VALUES NOTE: • ECM is located in the engine room left side near battery. • Specification data are reference values. • Pulse signal is measured by CONSULT.
