INSPECTION PROCEDURE
HINT:
The switch described in this text is a switch for transmitting signals, whi\
ch is built in the door control transmit-
ter.
1CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS (See page 73±15)
NG Go to step 2
OK
NORMAL
2 CHECK THAT TRANSMITTER LED LIGHTS UP
(a) Check that the transmitter LED lights up 3 times when the switch is pres\
sed 3 times. NG Go to step 8
OK
3 CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS (STANDARD OPERA- TION)
(a) Check if the UNLOCK±LOCK operates in standard operation.
NOTICE:
Standardized test procedure: Press the transmitter switch for 1 second, directing the beam to driv-
er 's door outside handle from a distance of 1 m (39.4 in.). The transmitte\
r should be pointed directly
at the door handle, i.e. at 90
angle to the vehicle body.
NG Go to step 4
OK
REPLACE TRANSMITTER SUB±ASSY MODULE SET DOOR CONTROL
4 CONFIRM ROOM LAMP ON
(a) Check that the room lamp lights up.
HINT:

SECURITY INDICATOR CIRCUIT
CIRCUIT DESCRIPTION
Even in the disarmed state, the security indicator flashes due to a signal output from the immobiliser system.
The security indicator always flashes when it receives a signal from the immobiliser system at any time in
the armed state.
The theft warning ECU causes the security indicator to light up or blink only during the customizing function
mode or the add mode of the transmitter.

INSPECTION PROCEDURE
1 CHECK REAR WINDOW DEFOGGER SWITCH ASSY (SECURITY INDICATOR)
(a) Remove the defogger switch.
(b) Apply 12 V positive voltage between each terminal of the
defogger switch connector, and check the lighting condi-
tion of the security indicator.
Standard:
Measurement ConditionSpecified Condition
Battery positive (+)
Terminal 8
Battery negative (±)
Terminal 1Lights up
NOTICE:

If the positive (+) lead and the negative (±) lead are in-
correctly connected, the security indicator does not
light up.

Voltage of more than 12 V will damage the security in-
dicator.

If the voltage is too low, the security indicator does
not light up.

INSPECTION PROCEDURE
HINT:
In case of using the hand±held tester, start the inspection from step1, and in case of not using the hand±held
tester, start from step 2.
1 READ VALUE OF HAND±HELD TESTER
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the hand±held tester main switch ON.
(c) Select the item ºSTOP LIGHT SWº in the DATA LIST and read the displayed value.

HINT:
Check with your hand to confirm that the belt has not slipped out
of the groove on the bottom of the pulley.
5. VISUALLY CHECK GENERATOR WIRING
(a) Check that the wiring is in good condition.
6. LISTEN FOR ABNORMAL NOISES FROM GENERATOR
(a) Check that there is no abnormal noise from the generator while the engine is running.
7. INSPECT CHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch ON. Check that the charge warning light comes on.
(b) Start the engine and check that the light goes off.
HINT:
If the light does not operate as specified, troubleshoot the charge warning light circuit.
8. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) According to the following procedure, connect an amme-
ter and voltmeter as shown in the illustration.
(1) Disconnect the wire from terminal B of the generator
and connect it to the negative (±) lead of the amme-
ter.
(2) Connect the positive (+) lead of the ammeter to ter-
minal B of the generator
(3) Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
(4) Ground the negative (±) lead of the voltmeter.
(b) Check the charging circuit.
(1) Keep the engine speed at 2,000 rpm, check the
reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 12.9 to 14.9 V
HINT:

If the voltmeter reading is more than standard voltage, re-
place the voltage regulator.

If the voltmeter reading is less than the standard voltage,
check the voltage regulator and generator as follows:
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) Keep the engine speed at 2,000 rpm, turn on the high beam headlights and turn the heater blower
switch to the ºHIº position.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
HINT:

If the ammeter reading is less than standard amperage, repair the generator.

If the battery is fully charged, the indication will sometimes be less than standard amperage.
