14. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transmission and engine by measuring
the stall speeds in the D and R positions.
NOTICE:

Do the test at normal operating fluid temperature 70 to 80 °C (158 to 176 °F).

Do not continuously run this test longer than 5 seconds.

To ensure safety, conduct this test in a wide, clear level area which provides good traction.

The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock all 4 wheels.
(2) Connect an OBD II scan tool or hand-held tester to DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressing firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
Quickly read the stall speed at this time.
Stall speed: 2,150 ± 150 rpm
(7) Do the same test in R position.
Stall speed: 2,150 ± 150 rpm
Evaluation:
ProblemPossible cause
(a) Engine stall speed low in D and R positions

Engine output may be insufficient

Stator one-way clutch is not operating properly
HINT: If the value is less than the specified value by 600 rpm or
more, the torque converter could be faulty.
(b) Engine stall speed high in D position

Line pressure too low

Clutch No. 1 (C
1) slipping

One-way clutch No.3 (F
3) not operating properly
(c) Engine stall speed high in R position

Line pressure too low

Brake No. 4 (B
4) slipping

Clutch No. 3 (C
3) slipping

One-way clutch No.1 (F
1) not operating properly
(d) Engine stall speed high in D and R positions

1. ABS Operation
If the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all the four
wheels to automatically avoid wheel locking and ensure the directional and steering stability of the vehicle. If the brake pedal
is depressed suddenly, the ABS & BA & TRAC & VSC ECU controls the solenoids in the actuators using the signals from the
sensors to move the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If the
ABS & BA & TRAC & VSC ECU detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the
solenoids in the actuators to increase the braking pressure.
2. Traction Control Operation
The traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, slipping of the
wheels which may occur at start or acceleration of the vehicle, to ensure an optimal driving power and vehicle stability
corresponding to the road conditions.
3. VSC Operation
Unexpected road conditions, vehicle speed, emergency situation, and any other external factors may cause large under- or
over-steering of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes to
reduce the under- or over-steering.
To reduce large over-steering :
If the VSC system determines that the over-steering is large, it activates the brakes for the outer turning wheels depending
on the degree of the over-steering to produce the moment toward the outside of the vehicle and reduce the over-steering.
To reduce large under-steering :
If the VSC system determines that the under-steering is large, it controls the engine power and activates the rear wheel
brakes to reduce the under-steering.
VSC indicator light
If an error occurs in the VSC system, the VSC indicator lights up to warn the driver.
4. Traction Mode and VSC Function
When the center differential of the transfer is locked, the VSC function is turned off. At this time, the VSC OFF indicator light
in the combination meter will come on, and informs the driver that the VSC function is OFF.
5. Mutual System Control
To efficiently operate the VSC system at its optimal level, the VSC system and other control systems are mutually controlled
while the VSC system is being operated.
Engine throttle control
The engine power does not interfere with the VSC brake control by controlling the opening of the throttle and reducing the
engine output.
Engine control and electronically controlled transmission control
The strong braking force does not interfere with the braking force control of the VSC system by turning off the accel. and
reducing changes in the driving torque at shift-down.
VSC system operation indication
The slip indicator light flashes and the buzzer sounds intermittently to warn the driver that the current road is slippery, while
the VSC system is being operated.
6. Fail Safe Function
If an error occurs in the ABS & BA & TRAC & VSC ECU, sensor signals, and/or actuators, the ABS & BA & TRAC & VSC
ECU inhibits the brake actuator control and inputs the error signal to the engine control module. According to the error signal,
the brake actuator turns off the solenoid and the engine control module rejects any electronically controlled throttle open
request from the VSC system. As a result, the vehicle functions without the ABS, BA, TRAC, and VSC systems.
