ta in threshold (turn ON), the SRS-ECU sen ds an
ignition signal to the air bag modules (squ ibs) and
seat belt with pre-te nsioners (squibs) on the driver
and p asseng er sides, thus inflating the air bag s and
operating the seat belt with pre -tensioner s.
SEAT BEL T RETRACT OR WITH FORCE
LIMITE R
The driver ’s /front p asseng er’s seat belt retractor has
been e quipped with a force limit er. The force limiter
is a device which operat es when a predetermined
force is applied, an d limits the for ce.
OPERA TION

SensorVehicle speed sensor (ABS-ECU)Sends the vehicle speed signal to the electric power
steering-ECU.
Torque sensorDetects a steering force, converts it into the voltage signal,
and then sends the signal to the electric power
steering-ECU.
ActuatorMotorGenerates assist torque by the steering operation to the
steering gear using the signals sent from the electric power
steering-ECU.
Electric power steering warning
lampWarns a driver of the system malfunction using the signal
sent from the electric power steering-ECU.
Electric power steering-ECUControl the actuator (motor) based on the signal sent from

DIAGNOSIS CODE SET
For more information about diagnosis code output,
refer to the Workshop Manual.
SWS INPUT SIGNAL CHECK USING
M.U.T.-III
When the M.U.T.-III is connected to the diagnosis
connector and any of the SWS-linked switches is
operated, the PC buzzer sounds to evaluate whether
the switch is normal or not.
SWS INPUT SIGNAL CHECK AND ECU
CHECK BY USING SWS MONITOR
The switch signals sent by ECUs and the operations
of these ECUs can be confirmed by using the SWS
monitor and the M.U.T.-III.
