AND Troubleshooting ,
CHECK AT THE ENGINE
TERMINAL VOLTAGE CHECK CHART1. Connect a needle-nosed wire probe (paper
etc.) to
a
probe.
2.insert the needle-nosed wire probe into each of the ECM
connector terminals from the wire side, and measure the
voltage referring to the check chart.
NOTE
1.Measure voltage with the ECM connectors connected.
2. You may find it convenient to pull out the ECM to
make it easier to reach the connector terminals.’
3.Checks don’t have to be carried out in the order gi ven
in the chart.
Caution
Short-circuiting the positive
probe between a con-
nector terminal and ground
vehicle
wiring, the sensor, ECM, or all three. Use care to pre-
vent this!
3.If voltmeter division from standard value, check
the corresponding sensor, actuator and related elec trical
wiring, then repair or replace.
4. After repair or replacement,, recheck with the v oltmeter
to confirm that the repair has corrected the proble m.

TERMINAL RESISTANCE
1. Turn the ignition switch off.
2. Disconnect the ECM connector.
3.Measure the resistance and check for continuity bet ween
the terminals of theECM
referring to the check
NOTE
1.When measuring resistance and checking continuity’
a harness for checking contact pin pressure should’
be used instead of inserting a test probe.
2.Checks do not have to be carried in the
given in this chart.,
Caution
If resistance or continuity performed on
the wrong terminals, damage to the vehicle wiring,
sensors,
and/or ohmmeter may occur.
Use care to prevent this!
4. If the ohmmeter shows
from the normal
condition, check the corresponding sensor, actuator and
related electrical wiring, and then repair or replace.
5. After repair or replacement, recheck with the oh mmeter
to confirm that the repair or replacement
corrected
the problem.
