ECM Terminals and Reference Value
PREPARATION
Perform all voltage measurements with all the connectors con-
nected. Measure ECM terminal voltage at the nearest connector to
the sensors or actuators to be measured as accessing ECM termi-
nals from outside is impossible.
I
Use extreme care not to touch 2 pins at the same time.
I
Data is for comparison and may not be exact.
I
Use care not to enlarge the opening to keep the seal in good
condition.
Be sure ECM unit is properly grounded before checking.
