The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.

SRS
NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionary
instructions and the procedure and precautions in the Repair Manual for the applicable model year.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information
when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.
Work must be started after 90 seconds from when the ignition switch is turned to the ºLOCKº position and the
negative (±) terminal cable is disconnected from the battery.
(The SRS is equipped with a back±up power source so that if work is started within 90 seconds from
disconnecting the negative (±) terminal cable of the battery, the SRS may be deployed.)
When the negative (±) terminal cable is disconnected from the battery, the memory of the clock and audio system will be
canceled. So before starting work, make a record of the contents memorized in the audio memory system. When work is
finished, reset the audio systems as they were before and adjust the clock. To avoid erasing the memory in each
memory system, never use a back±up power supply from outside the vehicle.
Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.
Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner,
center airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly directly to hot air or
flames.
Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag
assembly, side airbag assembly, seat belt pretensioner, center airbag sensor assembly, front airbag sensor assembly
and side airbag sensor assembly should be inspected.
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt
pretensioner, center airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly in order to
reuse it.
If the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, center airbag
sensor assembly, front airbag sensor assembly or side airbag sensor assembly has been dropped, or if there are
cracks, dents or other defects in the case, bracket or connector, replace them with new ones.
Use a volt/ohmmeter with high impedance (10 kW/V minimum) for troubleshooting the system's electrical circuits.
Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices.
After work on the SRS is completed, perform the SRS warning light check.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair
Manual.
SRS
The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts.
When the ignition SW is turned to ACC or ON, current from the CIG fuse flows to TERMINAL (B) 6 of the center airbag
sensor assembly. Only when the ignition SW is on does the current flow from the IGN fuse to TERMINAL (B) 5 of the center
airbag sensor assembly.
If an accident occurs while driving, when the frontal impact exceeds a set level, current from the CIG or IGN fuse flows to
TERMINALS (B) 14, (B) 10, (A) 2 and (C) 5 of the center airbag sensor assembly to TERMINAL 1 of the airbag squibs and
the pretensioners to TERMINAL 2 to TERMINALS (B) 13, (B) 11, (A) 1 and (C) 6 of the center airbag sensor assembly to
TERMINAL (B) 27, (B) 28 or BODY GROUND to GROUND, so that current flows to the front airbag squibs and the
pretensioners and causes them to operate.
When the side impact also exceeds a set level, current from the CIG or IGN fuse flows to TERMINALS (A) 5, (C) 2, (A) 2 and
(C) 5 of the center airbag sensor assembly to TERMINAL 1 of the side airbag squibs and the pretensioners to TERMINAL 2
to TERMINALS (A) 6, (C) 1, (A) 1 and (C) 6 of the center airbag sensor assembly to TERMINAL (B) 27, (B) 28 or BODY
GROUND to GROUND, causing side airbag squibs and the pretensioners to operate.
The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.
The airbag stored inside the passenger's instrument panel is instantaneously expanded to soften the shock to the front
passenger.
Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger.
The pretensioners make sure of the seat belt restrainability.

Current always flows to TERMINAL 1 of the integration relay through the DOME fuse.
1. SEAT BELT WARNING SYSTEM
When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 7 of the integration relay. At the same
time, current flows to TERMINAL 9 of the relay from the GAUGE fuse through the seat belt warning light. This current
activates the relay and the current flowing through the warning light flows from TERMINAL 9 of the relay to TERMINAL 10 to
GROUND, causing the warning light to light up. A buckle SW off signal is input to TERMINAL 8 of the relay to TERMINAL 10
to GROUND, causing the warning light to light up. A buckle SW off signal is input to TERMINAL 8 of the relay, the current
flowing to TERMINAL 1 of the relay flows from TERMINAL 10 to GROUND and the seat belt warning buzzer sounds for
approx. 6 seconds. However, if the seat belt is put on during this period (While the buzzer is sounding), signal input to
TERMINAL 8 of the relay stops and the current flow from TERMINAL 1 of the relay to TERMINAL 10 to GROUND is cut,
causing the buzzer to stop.
2. KEY REMINDER SYSTEM
With the ignition key inserted in the key cylinder (Unlock warning SW on), the ignition SW still off and driver's door open
(Door courtesy SW on), when a signal is input to TERMINAL 6 of the integration relay, the relay operates, current flows from
TERMINAL 1 of the relay to TERMINAL 10 to GROUND and key reminder buzzer sounds.
