*1: 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.
*2: Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to 

PG-97, "How to Handle Battery"

.

TERMINAL LAYOUT

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.
