CHECK AT THE ENGINE-ECU TERMINALS
TERMINAL VOLTAGE CHECK CHART
1. Connect a needle-nosed wire probe (test harness:
MB991223 or paper clip) to a voltmeter probe.
2. Insert the needle-nosed wire probe into each of the
engine-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-ECU
connectors connected.
(2) You may find it convenient to pull out the engine-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-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.

CHECK CHART FOR RESISTANCE AND CONTINUITY
BETWEEN TERMINALS
1. Turn the ignition switch to “LOCK” (OFF) position.
2. Disconnect the engine-ECU connector.
3. Measure the resistance and check for continuity between
the terminals of the engine-ECU harness-side connector
while referring to the check chart.
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) Checking need not be carried out in the order given
in the chart.
Caution
If the terminals that should be checked are mistaken,
or if connector terminals are not correctly shorted
to earth, damage may be caused to the vehicle wiring,
sensors, engine-ECU and/or ohmmeter.
Be careful to prevent this!
4. If the ohmmeter shows any deviation from the standard
value, check the corresponding sensor, actuator and
related electrical wiring, and then repair or replace.
5. After repair or replacement, recheck with the ohmmeter
to confirm that the repair or replacement has corrected
the problem.

ALTERNATOR OUTPUT LINE VOLTAGE DROP TEST

This test determines whether the wiring from the
alternator “B” terminal to the battery (+) terminal
(including the fusible line) is in a good condition
or not.
(1) Always be sure to check the following before
the test.
DAlternator installation
DAlternator drive belt tension
(Refer to GROUP 11 - On-vehicle Service.)
DFusible link
DAbnormal noise from the alternator while
the engine is running
(2) Turn the ignition switch to the “LOCK” (OFF)
position.
(3) Disconnect the negative battery cable.
(4) Disconnect the alternator output wire from the
alternator “B” terminal and connect a DC test
ammeter with a range of 0 - 100 A in seriesbetween the “B” terminal and the disconnected
output wire. (Connect the (+) lead of the
ammeter to the “B” terminal, and then connect
the ( - ) lead of the ammeter to the disconnected
output wire.)
NOTE
An inductive-type ammeter which enables
measurements to be taken without
disconnecting the alternator output wire should
be recommended. Using this equipment will
lessen the possibility of a voltage drop caused
by a loose “B” terminal connection.
(5) Connect a digital-type voltmeter between the
alternator “B” terminal and the battery (+)
terminal. (Connect the (+) lead of the voltmeter
to the “B” terminal and the connect the ( - ) lead
of the voltmeter to the battery (+) cable.)

ENGINE ELECTRICAL -Charging System16-5
(6) Reconnect the negative battery cable.
(7) Connect a tachometer or the MUT-II.
(Refer to GROUP 11 - On-vehicle Service.)
(8) Leave the hood open.
(9) Start the engine.
(10)With the engine running at 2,500 r/min, turn
the headlamps and other lamps on and off
to adjust the alternator load so that the value
displayed on the ammeter is slightly above 30
A.
Adjust the engine speed by gradually
decreasing it until the value displayed on the
ammeter is 30 A. Take a reading of the value
displayed on the voltmeter at this time.
Limit: max. 0.3 V
NOTE
When the alternator output is high and the value
displayed on the ammeter does not decrease
until 30 A, set the value to 40 A. Read the
value displayed on the voltmeter at this time.
When the value range is 40 A, the limit is max.
0.4 V.(11) If the value displayed on the voltmeter is above
the limit value, there is probably a malfunction
in the alternator output wire, so check the wiring
between the alternator “B” terminal and the
battery (+) terminal (including fusible link).
If a terminal is not sufficiently tight or if the
harness has become discolored due to
overheating, repair and then test again.
(12)After the test, run the engine at idle.
(13)Turn off all lamps and the ignition switch.
(14)Remove the tachometer or the MUT-II.
(15)Disconnect the negative battery cable.
(16)Disconnect the ammeter and voltmeter.
(17)Connect the alternator output wire to the
alternator “B” terminal.
(18)Connect the negative battery cable.
