CHECK AT THE ENGINE-A/T-ECU TERMINALS
TERMINAL VOLTAGE CHECK CHART
1.
Connect a needle-nosed wire probe (test harness:
MB991223) to a voltmeter probe.
2.
Insert the needle-nosed wire probe into each of the
engine-A/T-ECU connector terminals from the wire side,
and measure the voltage while referring to the check
chart.
NOTE
(1) Make
the
voltage
measurement
with
the
engine-A/T-ECU connectors connected.
(2) You
may
find
it
convenient
to
pull
out
the
engine-A/T-ECU to make it easier to reach the
connector terminals.
(3) The checks can be carried out off the order given
in the chart.
Caution
Short-circuiting the positive (+) probe between a
connector terminal and earth could damage the
vehicle wiring, the sensor, engine-A/T-ECU or all of
them. Be careful to prevent this!
3.
If voltmeter shows any division from standard value, check
the corresponding sensor, actuator and related electrical
wiring, then repair or replace.
4.
After repair or replacement, recheck with the voltmeter
to confirm that the repair has corrected the problem.
