BC–38BRAKE CONTROL – VEHICLE STABILITY CONTROL SYSTEM
BC
(f) Check the yaw rate sensor.
(1) Move the shift lever to P and set the parking
brake lever.
(2) Check that the VSC warning light is blinking as
shown in the illustration.
(3) Keep the vehicle stationary on a level surface for
1 second or more.
(4) Shift the shift lever to the D position and drive
the vehicle at a speed of approximately 5 km/h
(3 mph), and turn the steering wheel either to the
left or right 90
or more to turn the vehicle
through 180
.
(5) Stop the vehicle, move the shift lever into the P
position, and then apply the parking brake.
(6) Check that the skid control buzzer sounds for 3
seconds.
HINT:
• If the skid control buzzer sounds, the signal
check has been completed normally.
• If the skid control buzzer does not sound,
check the skid control buzzer circuit (see
page BC-172).
• If the skid control buzzer still does not sound,
there is a malfunction in the yaw rate sensor,
so check for DTCs.
• Drive the vehicle in a 180
semi circle. At the
end of the turn, the direction of the vehicle
should be within 180 +-5
of its start position.
• Complete the vehicle turn within 20 seconds.
• Do not spin the wheels.
(g) w/ Downhill assist control only:
Check the downhill assist control operation switch.
(1) Check that the VSC warning light is blinking as
shown in the illustration.
(2) Check the downhill assist control switch.
1. Push the downhill assist control switch on.
2. Push the downhill assist control switch off.

DATA LIST / ACTIVE TEST
1. READ DATA LIST
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.

FAIL-SAFE CHART
If a problem occurs in the electric power steering system, the
P/S warning light will come on in the combination meter and
steering power assist will be stopped, fixed at a particular
point, or decreased simultaneously to protect the system.
Electronic power steering system
HINT:
The amount of power assist may be decreased to prevent the
motor and ECUs from overheating if the steering wheel is
continuously turned when the vehicle is either stopped or
driven at a low speed, or if the steering wheel is kept at either
full lock position for a long time. In such cases, the amount of
power assist returns to normal if the steering wheel is not
turned for approximately 10 minutes with the engine idling.
