BRAKE CONTROL – VEHICLE STABILITY CONTROL SYSTEMBC–55
BC
FAIL-SAFE CHART
1. FAIL SAFE OPERATION
• If there is a problem with any sensor signals or
actuator systems, the skid control ECU prohibits the
power supply to the ABS and TRACTION actuator
and informs the ECM of VSC system failure.
The ABS and TRACTION actuator turns off the
solenoids and the ECM s huts off VSC control (traction
control signal) from the skid control ECU accordingly,
the result being that it is as if the ABS, TRC and VSC
systems were not installed.
• ABS control is prohibited, but EBD control continues
as far as possible. If EBD control is impossible, the
BRAKE warning light comes on to warn the driver
(see page BC-44).
• If system components have any malfunctions before
starting control, the operation stops immediately. If
system components have any malfunctions during
control, the control stops gradually so as not to trigger
a sudden change in vehicle conditions.
If it is impossible to control the systems, the warning
light comes on to inform the driver of malfunctions in
the systems (see page BC-44).
HINT:
• If the ABS system malfunctions, the brake system
operates normally without the ABS system.
• If the brake actuator malfunctions, a gradual loss of
brake performance is expected, and ABS system
control is prohibited.

HINT:
Using the intelligent tester's DATA LIST allows switch,
sensor, actuator and other item values to be read without
out removing any parts. Reading the DATA LIST early in
troubleshooting is one way to save time.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Turn the intelligent tester on.
(d) Read the DATA LIST according to the display on the
tester.

SUPPLEMENTAL RESTRAINT SYSTEM – AIRBAG SYSTEMRS–25
RS
SYSTEM DESCRIPTION
1. GENERAL
(a) In conjunction with an impact absorbing structure for
a frontal collision, the SRS (Supplemental Restraint
System) driver airbag, front passenger airbag and
driver side knee airbag were designed to
supplement seat belts in the event of a frontal
collision in order to help reduce shock to the head,
chest and knee of the driver and front passenger.
This system is a 3-sensor type airbag system to
detect the impact during a frontal collision using the
center airbag sensor and front airbag sensors. It
also operates the airbag system and seat belt
pretensioner.
(b) In order to detect the extent of the collision during
the initial stages of the collision in further detail, the
front airbag sensors have been changed from
mechanical type to electrical type deceleration
sensors. Accordingly, the deployment of the driver
airbag and front passenger airbag is controlled in
two stages according to the severity of the impact.
(c) In conjunction with an impact absorbing structure for
a side collision, the side airbag and curtain shield
airbag were designed to help reduce shock to the
driver and front passenger in the event of a side
collision.
(d) A curtain shield airbag that helps reduce shock to
the front and rear seat occupants with a single
curtain shield airbag has been adopted. In
conjunction with this system, the side airbag
sensors have been installed at the bottom of the
center pillars and rear airbag sensors have been
installed at the bottom of the rear pillars.
(e) In this system, a front side collision is detected by
the side airbag sensor in order to simultaneously
deploy the side airbag. A rear side collision is
detected by the rear airbag sensor and the center
airbag sensor in order to deploy the side airbag and
curtain shield airbag.
(f) The center airbag sensor sends the airbag
deployment signal to the ECM through the CAN
(Controller Area Network) to operate the fuel pump
control.
2. CONSTRUCTION AND OPERATION
(a) FRONT AIRBAG SENSOR
(1) The front airbag sensors are installed on the
right and left radiator supports.
(2) The front airbag sensor consists of the
deceleration sensor.
