REGULATED VOLTAGE TESTM1161001100666
Required Special Tools:
: Diagnostic Tool (MUT-III)

MB991827: MUT-III USB Cable
MB991910: MUT-III Main Harness A
MB998467: Alternator Harness Connector
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.

CHARGING SYSTEM
ENGINE ELECTRICAL16-11
11.Increase the engine speed to 2,500 r/min.
12.Read the value displayed on the voltmeter when
the current output by the alternator becomes 10 A
or less.
13.If the voltage reading conforms to the value in the
voltage regulation table, then the voltage regulator
is operating normally.
If the voltage is outside the standard value, there
is a malfunction of the voltage regulator or the
alternator (Refer to the following table).14.After the test, lower the engine speed to idle.
15.Turn the ignition switch to the "LOCK" (OFF)
position.
16.Disconnect the engine tachometer or diagnostic
tool .
17.Disconnect the negative battery cable.
18.Disconnect the ammeter and voltmeter.
19.Connect the negative battery cable.
20.Run the engine for 10 minutes at an idle.

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.

SPARK PLUG TESTM1163001500143
1. Remove the spark plug and connect to the ignition coil.
2. Ground the spark plug outer electrode (body), and crank the
engine.
Check that there is an electrical discharge between the
electrodes at this time.
SPARK PLUG CHECK AND CLEANING M1163004300397
Do not attempt to adjust the gap of the iridium plug.
Cleaning of the iridium plug may result in damage to
the iridium tips. Therefore, if carbon deposits must be
removed, use a plug cleaner and complete cleaning
within 20 seconds to protect the electrode. Do not use a
wire brush.
Check the plug gap and replace if the limit is exceeded.

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).
