*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.

• Connect a break-out box (EG17550000) and harness adapter (EG17550400) between the ECM and ECM

harness connector.

- Use extreme care not to 2 pins at one time.

- Data is for comparison and may not be exact.

• Specification data are reference values and are measured between each terminal and ground.

• Pulse signal is measured by CONSULT.
