9A1-4 RESTRAINT CONTROL SYSTEM
cautions in the service manual and on warning labels
attached to SRS components.
Basic Electrical Circuits
You should understand the basic theory of electricity
including series and parallel circuits, and understand
the voltage drops across series resistors. You should
know the meaning of voltage (volts), current (amps),
and resistance (ohms). You should understand what
happens in a circuit with an open or a shorted wire. You
should be able to read and understand a wiring
diagram.
“Flash Code” Diagnostics
Flash code diagnostics can be used to read active
codes and to determine if history codes are present but
cannot be used to clear codes or read history codes.
Flash code diagnostics is enabled by grounding by
terminal 4 shorting to terminal 13 of the DLC connector
with the ignition switch “ON”. Grounding terminal 4 of
the DLC connector pulls the “Diagnostics Request”
input (Terminal 1) of the SRS control unit low and
signals the SRS control unit to enter the flash code
diagnostic display mode.

4C2-2 SHIFT ON THE FLY SYSTEM
Shift On The Fly System
Outline of Shift on The Fly System
The shift on the fly system switches between 2 wheel
drive (2WD) and 4 wheel drive (4WD) electrically b
y
driver's pressing the 4WD switch (push button type) on
instrument panel.
This system controls below operations.
1.
Shifting the transfer front output gear (Connecting to,
and disconnecting from, front propeller shaft b
y
motor actuator).
2. Retrial of shifting the transfer front output gear.
3. Connecting front wheels to, and disconnecting them
from, the front axles by axle motor actuator.
4. Indicator on instrument panel.
5. 4WD out signal to other Electronic Hydraulic Control
Unit.

Structure and Operation
Structure
Side
a shows P-valve ; side b shows bypass valve.
Bypass valve seals the routes
4 and 5 using the seal 2at
the piston
1 end.
In addition, spring
3 presses against the piston 1, and in
order to seal out the route
4 and route 5 sufficiently, spring
3 presses seal 2 against cylinder end surface.
The left figure is a characteristic curve diagram.
