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 wh en measuring input/output voltage. Doing so may result in dam-
age to the ECMs transistor. Use a ground ot her than ECM terminals, such as the ground.
