3. INSPECT V-RIBBED BELT
(a) Visually check the belt for excessive wear, frayed
cords, etc.
If any defects are found, replace the V-ribbed belt.
HINT:
Cracks on the rib side of the belt are considered
acceptable. If the belt has chunks missing from the
ribs, it should be replaced.
(b) Check that the belt fits properly in the ribbed
grooves.
HINT:
Confirm by hand that the belt has not slipped out of
the grooves on the bottom of the pulley.
4. INSPECT GENERATOR WIRING
(a) Visually check the generator wiring.
(1) Check that the wiring is in good condition.
5. CHECK FOR ABNORMAL NOISES
(a) Listen for abnormal noises from the generator.
(1) Check that no abnormal noises are heard from
the generator while the engine is running.
6. 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.
If the light does not operate as specified,
troubleshoot the charge warning light circuit.
7. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) Connect a voltmeter and ammeter to the charging
circuit as follows.
(1) Disconnect the wire from terminal B of the
generator, then connect it to the negative (-)
lead of an ammeter.
(2) Connect the positive (+) lead of the ammeter to
terminal B of the generator.
(3) Connect the positive (+) lead of a voltmeter to
terminal 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 and check
the reading on the ammeter and voltmeter.
Standard amperage:
10 A or less
Standard voltage:
12.1 to 15.4 V
If the result is not as specified, replace the
generator.
HINT:
If the battery is not fully charged, the ammeter
reading will sometimes be more than the
standard amperage.

SEAT BELT – SEAT BELT WARNING SYSTEMSB–3
SB
SYSTEM DESCRIPTION
1. DRIVER SEAT BELT WARNING LIGHT
(a) When the driver seat belt is not fastened with the
ignition switch ON, the driver seat belt warning light
on the combination meter comes on to inform the
driver. The center airbag sensor detects the driver
seat belt status and sends signals to the
combination meter through the CAN bus line.
2. PASSENGER SEAT BELT WARNING LIGHT
(a) for Automatic air conditioning system:
When the passenger seat belt is not fastened with
the ignition switch ON and the passenger seat
occupied, check that the passenger seat belt
warning light on the heater control panel display
blinks. The combination meter detects the
passenger seat belt status and whether the
passenger seat is occupied.
(b) for Manual air conditioning system:
When the passenger seat belt is not fastened with
the ignition switch ON and the passenger seat
occupied, check that the passenger seat belt
warning light on the clock panel blinks. The
combination meter detects the passenger seat belt
status and whether the passenger seat is occupied.

ENGINE IMMOBILISER – ENGINE IMMOBILISER SYSTEMEI–3

SYSTEM DESCRIPTION
1. ENGINE IMMOBILISER SYSTEM DESCRIPTION
The engine immobiliser system is designed to prevent
the vehicle from being stolen. This system uses a
transponder key ECU that stores the key codes of
authorized ignition keys. If an attempt is made to start
the engine using an unauthorized key, the ECU sends a
signal to the ECM to prohibit fuel delivery and ignition,
effectively disabling the engine.
2. FUNCTION OF MAIN COMPONENT
3. SYSTEM FUNCTION
• When the transponder key ECU detects that the
unlock warning switch is ON, the ECU provides
current to the transponder key coil and produces a
faint electric wave. A transponder chip in the key grip
receives the wave and outputs a key ID code signal.
The transponder key coil receives this signal, the
transponder key amplifier amplifies it, and then the
signal is transmitted to the ECU. The ECU matches
the key's ID code with the vehicle's ID code, which
was previously registered in the ECU and then
communicates the results to the ECM using SFI
communication.
• After the identification results show that the key's ID
code matches the vehicle's ID code and the ECU has
confirmed their match: 1) the engine immobiliser
system is canceled and the engine starting controls
(fuel injection control and ignition control) enter
standby mode; and 2) the ECU receives a security
indicator light signal, and turns the security indicator
light OFF.
Component Outline
Transponder key coil/amplifierWhen key is inserted into ignition key cylinder, key coil receives key
code. Then amplifier amplifies ID code and outputs it to transponder
key ECU.
Unlock warning switch assemblyDetects whether key is in ignition key cylinder and outputs results to
transponder key ECU
ECMThrough SFI communication, ECM receives ID verification results
from transponder key ECU. ECM also verifies ECUs. Then ECM
judges whether or not to immobilize engine.
Security indicator lightDepending on operation of transponder key ECU, interior security
indicator light comes on or starts blinking
