ECM EC-545 < ECU DIAGNOSIS INFORMATION > [VK56DE] C D E F G H I J K L M A EC N P O *1: Accelerator pedal position sensor 2 signal and throttle position sensor 2 signal are converted by ECM internally. Thus, they differ ECM Harness Connector Terminal Layout INFOID:0000000007358448 ECM Terminal and Reference Value INFOID:0000000007358449 PREPARATION ECM is located in the engine room passenger side behind battery. ECM INSPECTION TABLE Specification data are reference values and are measured between each terminal and ground. Pulse signal is measured by CONSULT. CAUTION: Never use ECM ground terminals when measuring input/output voltage. Doing so may result in dam- age to the ECMs transistor. Use a ground other than ECM terminals, such as the ground.
