INDUCTION SYSTEM
THROTTLE VALVE ACTUATOR
YAA1F540
The throttle actuator is actuated by the Engine Control Module (ECM) according to the position of the accelerator pedal
position.
It has two potentiometers which signal the position of the throttle valve to the ECM to enable it to recognize the various
engine load states.
Ignition “Off”
In the de-- energized states the throttle valve position is determined to be spring capsule.
Ignition “On”
When the ignition S/W on the servo motor in the throttle actuator is operated by the ECM. The throttle valve adopts a
position in line with the coolant temperature.
Closed position
In the closed throttle position, the servo motor controls engine speed by operating the throttle valve further (greater
mixture) or closing it further (reduced mixture), depending on coolant temperature and engine load. When this is done,
the throttle valve can be closed further by the servo motor overcoming the force of the spring capsule (mechanical end
stop). If the actuator is de-- energized, the throttle valve is resting against the spring capsule.
Consequently, the throttle valve opening is a constant 10-- 12°approximately.
At no load, this produces an engine speed of about 1,800 rpm
Driving
When driving (part/full throttle), the servo motor controls the throttle valve in line with the various load states and ac-
cording to the input signals from the pedal value sensor according to the input signals from the pedal value sensor
according to the position of the accelerator pedal.
The function of the EA (electronic accelerator) in the ECM determines the opening angle of the throttle valve through
the throttle actuator. Further functions are;
DIdle speed control
DCruise control
DReducing engine torque for ASR/ABS operation
DElectronic accelerator emergency running
DStoring faults
DData transfer through CAN

Circuit Description
Cruise control is an automatic speed control system that maintain a desired driving speed without using the accelerator
pedal. The vehicle speed must be greater than 40 km/h to engage cruise control.

OPERATORS INTERFACES
There are three operator interfaces as the following;
•Gear Shift Control Lever
Driving Mode Selector
Indicator Light
Gear Shift Control lever
The transmission uses a conventional shift control lever.
The gear shift control lever can be moved from one
position to another within the staggered configuration
of the shift control lever gate to positively indicate the
gear selection.
DESCRIPTION AND OPERATION
BTRA M74 4WD AUTOMATIC
TRANSMISSION
The BTR Automotive Model 74 Four Speed Automatic
Transmission is an electronically controlled overdrive
four speed unit with a lock-up torque converter. The
lock-up torque converter results in lower engine speeds
at cruise and eliminates unnecessary slippage. These
features benefit the customer through improved fuel
economy and noise reduction.Of primary significance is the Transmission Control Mo-
dule (TCM) which is a microprocessor based control
system.
The TCM utilizes throttle position, rate of throttle open-
ing, engine speed, vehicle speed, transmission fluid
temperature, gear selector position and mode selector
inputs, and in some applications a Kickdown Switch
to control all shift feel and shift schedule aspects.
The TCM drives a single proportional solenoid multi-
plexed to three regulator valves to control all shift feel
aspects. The output pressure of this solenoid is con-
trolled as a function of transmission fluid temperature
to maintain consistent shift feel throughout the
operating range.
Shift scheduling is highly flexible, and several indepen-
dent schedules are programmed depending on the ve-
hicle.
Typically the NORMAL schedule is used to maximize
fuel economy and driveability, and a POWER schedule
is used to maximize performance. WINTER schedule
is used to facilitate starting in second gear. Configuration Max.

P - Park position prevents the vehicle from rolling
either forward or backward by locking the
transmission output shaft. The inhibitor switch
allows the engine to be started. For safety reasons,
the parking should be used in addition to the park
position. Do not select the Park position until the
vehicle comes to a complete stop because it
mechanically locks the output shaft.
R - Reverse allows the vehicle to be operated in a
rearward direction. The inhibitor switch enables re-
verse lamp operation.
