ECM Harness Connector Terminal LayoutNBS0003L
ECM Terminals and Reference ValueNBS0003M
PREPARATION
ECM (1) is located behind the passenger side instrument lower
panel. For this inspection, remove passenger side instrument lower
panel.
ECM INSPECTION TABLE
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-III.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECMs transistor. Use a ground other than ECM terminals, such as the ground.
