*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.
