ECM
*: Throttle position sensor 2 signal is converted by ECM internally. Thus, it differs from ECM terminal voltage signal.
TERMINAL LAYOUT
PHYSICAL VALUES
NOTE:
• ECM is located in the engine room left side near inverter with converter assembly.
• Specification data are reference values and are measured between each terminal and ground.
• Pulse signal is measured by CONSULT-III.
• If necessary, activate “INSPECTION MODE 1” (
CAUTION:
Do not 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.
