Specification data are reference values and are measured between each terminal and ground. Pulse signal is measured by CONSULT.

CAUTION: Never use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

TERMINAL NO.
