relay, VSV, actuator and other items to be operated
without removing any parts. Performing the ACTIVE
TEST early in troubleshooting is one way to save time.
The DATA LIST can be displayed during the ACTIVE
TEST.
(a) Connect the intelligent tester to the DLC3.

SB–14SEAT BELT – SEAT BELT WARNING SYSTEM
SB
DESCRIPTION
When the ignition switch is ON, the center airbag sensor transmits front seat inner belt status signals to
the combination meter through the CAN bus line. If the driver seat belt is not fastened, the combination
meter blinks the driver side seat belt warning light. If the seat belt is fastened, the warning light goes off.
NOTICE:
The seat belt warning system uses the CAN bus line. Before troubleshooting the seat belt warning
system, perform "COMMUNICATION FUNCTION CHECK" by following "HOW TO PROCEED WITH
TROUBLESHOOTING" to confirm that the communication systems are normal.

DESCRIPTION
When the ignition switch is ON, the center airbag sensor transmits front seat inner belt status signals to
the combination meter through the CAN bus line. If the front passenger seat belt is not fastened, the
heater control panel (automatic A/C) or clock (manual A/C) blinks the front passenger seat belt warning
light. If the seat belt is fastened, the warning light goes off.

HINT:
Connect the cable of the intelligent tester (with CAN
VIM) to the DLC3, turn the ignition switch ON and
attempt to use the tester. If the display indicates that
a communication error has occurred, there is a
problem either with the vehicle or with the tester.
• If communication is normal when the tester is
connected to another vehicle, inspect the DLC3
of the original vehicle.
• If communication is still not possible when the
tester is connected to another vehicle, the
problem may be in the tester itself. Consult the
Service Department listed in the tester's
instruction manual.
3. CHECK INDICATOR
(a) Turn the ignition switch ON.
(b) Check that the CRUISE main indicator light
illuminates when the cruise control main switch is
turned ON, and that the indicator light goes off when
the main switch is turned OFF.
HINT:
• If the indicator check result is not normal,
proceed to troubleshooting for the combination
meter section (see page ME-15).
• If a malfunction occurs in the speed sensor or
stop light switch, etc. during cruise control
driving, the ECM activates the AUTO CANCEL of
the cruise control and the CRUISE main indicator
light blinks to inform the driver of a malfunction.
At the same time, the malfunction is stored in
memory as a diagnostic trouble code.
DTC CHECK / CLEAR
1. CHECK DTC (USING INTELLIGENT TESTER)
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Read the DTCs by following the directions on the
tester screen.
HINT:
Refer to the intelligent tester operator's manual for
further details.
