This test determines whether the wiring from the
alternator "B" terminal to the positive battery terminal
(including the fusible link) is in good condition or not:
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
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. Connect a clamp-type DC test ammeter with a
range of 0
100 A to the alternator "B" terminal
output wire.
NOTE: The way of disconnecting the alternator
output wire and of connecting the ammeter is pos-
sibly not found the problem that the output current
is dropping due to the insufficient connection
between terminal "B" and the output wire.
5. Connect a digital-type voltmeter between the
alternator "B" terminal and the positive battery
terminal. (Connect the positive lead of the
voltmeter to the "B" terminal, and then connect the
negative lead of the voltmeter to the positive
battery cable.)
6. Reconnect the negative battery cable.
7. Connect an engine tachometer or diagnostic tool.
8. Leave the hood open.
9. Start the engine.

This test determines whether the alternator outputs
normal current. For best results, use a charging sys-
tem tester. If not available, follow the steps below.
Battery posts, terminals and related acces-
sories contain lead and lead compounds.
WASH HANDS AFTER HANDLING.
1. Before the test, always be sure to check the
following.
Alternator installation
Battery (Refer to GROUP 54A, Chassis Electrical
Battery On-vehicle Service Battery Check
P.54A-5.)
NOTE: The battery to be used should be slightly
discharged. The load in a fully-charged battery
will be insufficient and the test may not be able to
be carried out correctly.
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.
Never use clips to connect the wire. Loose
connections (for example, using clips) will
lead to a serious accident because of high
current.
4. Connect a clamp-type DC test ammeter with a
range of 0
120 A to the alternator "B" terminal
output wire.
5. Connect a voltmeter with a range of 0
20 V
between the alternator "B" terminal and ground.
(Connect the positive lead of the voltmeter to the
"B" terminal, and then connect the negative lead
of the voltmeter to ground.)
6. Connect the negative battery cable.
7. Connect an engine tachometer or diagnostic tool.
8. Leave the hood open.9. Check to be sure 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 "B" terminal and the battery positive
terminal or malfunctioning voltmeter.
10.After turning on the headlights, start the engine.
NOTE: Because the current from the battery will
soon drop after the engine is started, step 11
should be carried out as quickly as possible in
order to obtain the maximum current output value.
11.Immediately after setting the headlights to high
beam and turning the heater blower switch to the
highest position, increase the engine speed to
2,500 r/min and read the maximum current output
value displayed on the ammeter.
Limit value: 70 % of nominal current output
NOTE: For the nominal current output, refer to the
Alternator Specifications.
NOTE: The current output value will depend on
the electrical load and the temperature of the
alternator body.
NOTE: If the electrical load is small while testing,
the specified level of current may not be output
even though the alternator is normal. In such
cases, increase the electrical load by leaving the
headlights turned on for some time to discharge
the battery or by using the lighting system in
another vehicle, and then test again.
NOTE: The specified level of current also may not
be output if the temperature of the alternator body
or the ambient temperature is too high. In such
cases, cool the alternator and then test again.
12.The reading on the ammeter should be above the
limit value. If the reading is below the limit value
and the alternator output wire is normal, remove
the alternator from the engine and check the
alternator.
13.Run the engine at idle speed after the test.
14.Turn the ignition switch to the "LOCK" (OFF)
position.
15.Disconnect the engine tachometer or diagnostic
tool.
16.Disconnect the negative battery cable.
17.Disconnect the ammeter and voltmeter .
18.Connect the negative battery cable.
19.Run the engine for 10 minutes at an idle.

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

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.

KEYLESS ENTRY SYSTEM
BODY42-68
If none of the doors is opened or the ignition key
is not inserted in the ignition switch within 30 sec-
onds after the doors are unlocked using the
transmitter, the ETACS-ECU will relock the doors
automatically. This is called "Timer lock function."
This timer lock function prevents accidental
unlocking of doors. The adjustment function
allows you to change the timer lock period from 30 seconds (default setting) to 60, 120 or 180
seconds. For further details on using the
multi-center display (middle grade type) to adjust
the timer lock period, refer to GROUP 54B,
On-vehicle Service P.54B-486.
NOTE: The timer lock period begins when the doors
are unlocked, and ends when the doors is relocked
automatically.

HOW TO PERFORM VEHICLE IDENTIFICATION
NUMBER (VIN) WRITING
M1001011400063
The Vehicle Identification Number (VIN) is stored in the ECU by
the vehicle manufacture. If the VIN to be stored in the ECU is
eliminated fraudulently, the Malfunction Indicator Lamp (Check
Engine Lamp) illuminates and Diagnostic Trouble Code (DTC)
No.P0630 (VIN malfunction) is shown. When the ECU is
replaced, and entry of the VIN necessary due to DTC No.

MB991910: MUT-III Main Harness A (BLUE)
To prevent damage to DIAGNOSTIC TOOL (MUT-III), always
turn the ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting.
1. Connect Diagnostic Tool to the data link connector.
2. Turn the ignition switch to the "ON" position.
3. Confirm DTC No.P0630 (EEPROM malfunction) is not
shown.
NOTE: When DTC No. P0630 (EEPROM malfunction) is
shown, the VIN cannot be stored even if entered. Therefore,
the troubleshooting is performed when this DTC is shown.
4. Select "Coding" form the menu screen.
5. Select "VIN writing" form the menu screen.
6. Enter the VIN.
7. After entry of the VIN, turn the ignition switch to the "LOCK"
(OFF) position. After ten seconds or more passed, turn to
the "ON" position again.
8. Confirm DTC No.P0630 (VIN malfunction) is not shown.
NOTE: When DTC No.P0630 (VIN malfunction) is shown,
enter the VIN again because that would be not appropriate.
