REGULATED VOLTAGE TESTM1161001100666
Required Special Tools:
: Diagnostic Tool (MUT-III)
MB991824: V.C.I.
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.

ASSEMBLY SERVICE POINTS
.
>>A<< REGULATOR ASSEMBLY INSTALLATION
After installing the regulator assembly, insert a wire through the
hole provided on the rear bracket while pressing down on the
brush, and secure the brush.
NOTE: By inserting a wire, the brush will be secured in place,
and the installation of the rotor will be easier.
.
>>B<< ROTOR ASSEMBLY INSTALLATION
After installing the rotor, remove the wire used to secure the
brush.
INSPECTIONM1161001700099.
ROTOR CHECK
1. Check the continuity between the slip rings of the field coil. If
the resistance value is not within the standard value, replace
the rotor.
Standard value: approximately 2

IGNITION SYSTEM
ENGINE ELECTRICAL16-30
IGNITION SYSTEM
GENERAL DESCRIPTIONM1163000100528
This system is provided with six ignition coils with
built-in ignition power transistors for each of the cylin-
ders.
Interruption of the primary current flowing in the pri-
mary side of ignition coil generates a high voltage in
the secondary side of ignition coil.
The engine control unit (ECU) controls the three
ignition power transistors to turn them alternately ON
and OFF. This causes the primary currents in the
ignition coils to be alternately interrupted and allowed
to flow to fire the cylinders in the order 1-2-3-4-5-6.The ECU determines which ignition coil should be
controlled by means of the signals from the camshaft
position sensor which is incorporated in the camshaft
and from the crankshaft position sensor which is
incorporated in the crankshaft.
It also detects the crankshaft position to provide igni-
tion at the most appropriate timing in response to the
engine operation conditions.
When the engine is cold or operated at high alti-
tudes, the ignition timing is slightly advanced to pro-
vide optimum performance.
