This test determines whether the voltage regulator is
correctly controlling the alternator output voltage.
Battery posts, terminals and related acces-
sories contain lead and lead compounds.
WASH HANDS AFTER HANDLING.
1. Always be sure to check the following before the
test:
Alternator installation
Check to be sure that the battery installed in the
vehicle is fully charged. (Refer to GROUP 54A,
Chassis Electrical
Battery On-vehicle Service
Battery Check P.54A-5.)
Alternator drive belt tension (Refer to GROUP 00,
General
Maintenance Service Drive Belts
(For Alternator, Power Steering Pump and Air
Conditioning) (Check) P.00-39.)
Fusible link
Abnormal 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. Use the special tool (Alternator harness
connector: MB998467) to connect a digital-type
voltmeter between the alternator "S" terminal and
ground. (Connect the positive lead of the
voltmeter to the "S" terminal, and then connect the
negative lead of the voltmeter to a secure ground
or to the negative battery terminal.)
5. Connect a clamp-type DC test ammeter with a
range of 0
120 A to the alternator "B" terminal
output wire.
6. Reconnect the negative battery cable.
7. Connect an engine tachometer, or diagnostic tool.
8. Turn the ignition switch to the "ON" position and
check that the reading on the voltmeter is equal to
the battery positive voltage.
NOTE: If the voltage is 0 V, the cause is probably
an open circuit in the wire or fusible link between
the alternator "S" terminal and the battery positive
terminal or malfunctioning voltmeter.
9. Check to be sure that all lights and accessories
are off.
10.Start the engine.

IGNITION COIL CHECK M1163001200380
Check by the following procedure, and replace the coil if there
is a malfunction.
.
PRIMARY COIL AND IGNITION POWER
TRANSISTOR CONTINUITY CHECK
NOTE: No test can be performed on the Primary side of coil.
.
SECONDARY COIL CHECK
NOTE: It is impossible to check the secondary coil through the
continuity check as a diode is integrated in the secondary coil
circuit of this ignition coil. Accordingly, check the secondary coil
in the following procedure.
1. Disconnect the ignition coil connector.
2. Remove the ignition coil and install a new spark plug to the
ignition coil.
3. Connect the ignition coil connector.
4. Disable vehicle fuel pump by removing fuel pump relay or
disconnecting fuel pump connector D-18 (under rear seat).
5. Ground the side electrode of the spark plug and crank the
engine.
6. Check that spark is produced between the electrodes of the
spark plug.
7. If no spark is produced, replace the ignition coil with a new
one and recheck.
8. If spark is produced with the new ignition coil, replace the
old one as it is faulty. If no spark is produced again, the
ignition circuit is suspected as faulty. Check the ignition
circuit.
WINDSHIELD WIPER AND WASHER
EXTERIOR51-16
If the windshield intermittent wiper interval control is operated,
the wiper interval should change.
To prevent damage to diagnostic tool, always turn the igni-
tion switch to the "LOCK" (OFF) position before connect-
ing or disconnecting.
1. Connect diagnostic tool to the data link connector.
2. Turn the ignition switch to the "ON" position.
3. Operate diagnostic tool according to the procedure below to
display "Simulated Vehicle Speed Output."
(1) Select "SYSTEM SELECT."
(2) Select "SWS."
(3) Select "Simulated Vehicle Speed Output."
4. Holding the windshield intermittent wiper interval control,
input the simulated vehicle speed with diagnostic tool and
check that the wiper interval changes as the vehicle speed
changes.
5. If not, carry out the troubleshooting (Refer to GROUP 54B,
SWS Diagnosis P.54B-57).
WINDSHIELD WASHER FLUID SPRAY CHECKM1511018400060
The windshield washer nozzle aiming cannot be adjusted. If the
washer nozzles do not spray washer fluid within the windshield
wiper wiping area, check the nozzles as follows:
1. Check that the windshield washer nozzles are fitted on the
hood correctly, and reinstall them if necessary.
2. If the windshield washer nozzles are damaged, replace
them (Refer to P.51-23).

TROUBLESHOOTING CONTENTSM1001013300062
During diagnosis, a DTC code associated with
other system may be set when the ignition
switch is turned on with connector(s) discon-
nected. On completion, confirm all systems
for DTC code(s). If DTC code(s) are set, erase
them all.
When the DIAGNOSTIC TOOL (MUT-III)
detects a diagnostic trouble code, its display
informs users whether a mechanical problem
currently exists (“current trouble”) or whether
it existed before but normal operation has
been restored (“past trouble”). However, if an
MPI, TPMS or SRS airbag-related DTC is set,
“Active DTC/Stored DTC” is not displayed. In
this case, follow the diagnosis procedure for
current trouble.
If a trouble, detected in a CAN communica-
tion-capable system, can be reproduced,
diagnose the CAN bus lines (Refer to GROUP
54C, Can Bus Line Diagnostics Chart
P.54C-15 or P.54C-15).
Troubleshooting of electronic control systems for
which the MUT -III can be used follows the basic out-
line described below. Even in systems for which the
MUT-III cannot be used, part of these systems still
follow this outline.

If the MUT-III displays a diagnostic trouble code, find
the applicable inspection procedure according to this
chart.
5. SYMPTOM CHART
If there are symptoms, even though the MUT-III
shows that no DTCs are set, inspection procedures
for each symptom will be found by using this chart.
6. DIAGNOSTIC TROUBLE CODE
PROCEDURES
Indicates the inspection procedures corresponding to
each diagnostic trouble code. (Refer to P.00-9).
7. SYMPTOM PROCEDURES
Indicates the inspection procedures corresponding to
each symptom listed in the Symptom Chart (Refer to
P.00-9).
8. SERVICE DATA REFERENCE TABLE
Inspection items and normal judgment values have
been provided in this chart as reference information.
9. CHECK AT ECU TERMINALS
Terminal numbers for the ECU connectors, inspec-
tion items, and standard values have been provided
in this chart as reference information.
.
TERMINAL VOLTAGE CHECKS
1. Use correct tool to check each pin location on the
ENGINE-ECU Check harnes MB992044 and
measure with voltmeter.
Short-circuiting the positive (+) test probe
between a connector terminal and ground could
damage the vehicle wiring, the sensor, the ECU,
or all three. Use care to prevent this!
2. Insert the correct terminal tool into each of the
ENGINE-ECU check harness connector
terminals, and measure the voltage while referring
to the check chart.
NOTE: Measure voltage with the ECU connectors
connected.
You may find it convenient to pull out the ECU to
make it easier to connect the ENGINE-ECU check
harness.

HOW TO COPE WITH INTERMITTENT
MALFUNCTIONS
M1001013900064
Most intermittent malfunctions occur under certain conditions. If
those conditions can be identified, the cause will be easier to
find.
.
TO COPE WITH INTERMITTENT MALFUNCTION;
1. ASK THE CUSTOMER ABOUT THE
MALFUNCTION
Ask what it feels like, what it sounds like, etc. Then ask about
driving conditions, weather, frequency of occurrence, and so
on.
.
2. DETERMINE THE CONDITIONS FROM THE
CUSTOMER'S RESPONSES
Typically, almost all intermittent malfunctions occur from condi-
tions like vibration, temperature and/or moisture change, poor
connections. From the customer's responses, it should be rea-
soned which condition is most likely.
.
3. USE SIMULATION TEST
Use the simulation tests below to attempt to duplicate the cus-
tomer's complaint. Determine the most likely circuit(s) and per-
form the simulation tests on the connectors and parts of that
circuit(s). Be sure to use the inspection procedures provided for
diagnostic trouble codes and trouble symptoms.
For temperature and/or moisture condition related intermittent
malfunctions, try to change the conditions of the suspected cir-
cuit components, then use the simulation tests below.
.

GENERAL00-15
4. VERIFY THE INTERMITTENT MALFUNCTION IS
ELIMINATED
Repair the malfunctioning part and try to duplicate the condi-
tion(s) again to verify the intermittent malfunction has been
eliminated.
.
SIMULATION TESTS
NOTE: In case of difficulty in finding the cause of the intermit-
tent malfunction, the data recorder function in the
DIAGNOSTIC TOOL (MUT-III) is effective.
For these simulation tests, shake, then gently bend, pull, and
twist the wiring of each of these examples to duplicate the inter-
mittent malfunction.
Shake the connector up-and-down, and right-and-left.
Shake the wiring harness up-and-down, and right-and-left.
Especially, check the splice points of wiring harnesses care-
fully. Refer to GROUP 00E, Harness Connector Inspection
P.00E-2.
Shake the part or sensor.
