*: Accelerator pedal position sensor 2 signal and throttle position sensor 2 signal are converted by ECM internally. Thus, they differ from
ECM terminals voltage signal.
*: Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to
.

PHYSICAL VALUES
NOTE:
• ECM is located in the engine room left side near battery.
• Specification data are reference values and are measured between each terminal and ground.
• Pulse signal is measured by CONSULT.
