SUPPLEMENTAL RESTRAINT SYSTEM – AIRBAG SYSTEMRS–27
RS
• The center airbag sensor receives signals
from the deceleration sensor and the
electronic safing sensor built into the center
airbag sensor and the rear airbag sensor, and
determines whether or not the side airbag
and curtain shield airbag should be activated,
and diagnoses system malfunctions.
• The center airbag sensor sends the airbag
deployment signal to ECM through the CAN
to operate the fuel pump control.
(2) Deceleration sensor and ignition control circuit
• The deceleration sensor is built into the
center airbag sensor.
• The ignition control circuit performs
calculations based on the signal output from
the deceleration sensors of the center airbag
sensor and front airbag sensor. If the
calculated values are greater than the
specified values, it activates the deployment
operation.
(3) Safing sensor
The safing sensor is built into the center airbag
sensor. During a frontal collision, the sensor
turns on and outputs an ON signal to the center
airbag sensor if a deceleration rate greater than
the specified value is applied to the safing
sensor.
(4) Electronic safing sensor
The electronic safing sensor is built into the
center airbag sensor. During a side collision, the
sensor turns on and outputs an ON signal to the
center airbag sensor if a deceleration rate
greater than the specified value is applied to the
electronic safing sensor.
(5) Back-up power source
The back-up power source consists of a power
supply capacitor and a DC-DC converter. When
the power system does not function during a
collision, the power supply capacitor discharges
and supplies electric power to the system. The
DC-DC converter operates as a boosting
transformer when the battery voltage falls below
a predetermined level.
(6) Diagnostic circuit
This circuit constantly diagnoses system
malfunctions. When a malfunction is detected, it
lights up the SRS warning light on the telltale
light to inform the driver.
(7) Memory circuit
When a malfunction is detected in the diagnostic
circuit, it is coded and stored in the memory
circuit.

(d) Light auto turn off system:
When the headlights and taillights are illuminated by
the operation of the light control switch, if the
ignition switch is turned OFF, this system continues
illuminating the headlights and taillights for
approximately 30 seconds, and then turns off the
lights. However, when all the doors are locked
manually, using the door lock button, using the key
or pressing LOCK on the transmitter turns the
headlights and taillights off immediately.
(1) The main body ECU receives the following
signals (F).
• Door courtesy switch signal
• Ignition switch signal
(2) The main body ECU controls the following
signals based on the signals listed in F (G).
