4. CLEAR ZERO POINT CALIBRATION DATA (When not
Using Intelligent Tester)
(a) Clear the zero point calibration data.
(1) Turn the ignition switch ON.
(2) The warning light and indicator light come on for
3 seconds to indicate that the initial check is
completed.
(3) Using SST, connect and disconnect terminals 12
(TS) and 4 (CG) of the DLC3 4 times or more
within 8 seconds.
SST 09843-18040
(4) Check that the VSC warning light comes on.
(5) Remove SST from the terminals of the DLC3.
(6) Using a check wire, perform the zero point
calibration of the yaw rate and deceleration
sensor.
CAUTION:
If the ignition switch is turned ON for more
than 15 seconds with the shift lever in the P
position after zero point of the yaw rate and
acceleration sensor has been cleared, only
the zero point of the yaw rate sensor will be
stored. If the vehicle is driven under this
condition, the skid control ECU will
recognize that zero point calibration of the
acceleration sensor is not completed and will
indicate that there is a malfunction in the
VSC system using the indicator light.
5. PERFORM ZERO POINT CALIBRATION OF YAW
RATE AND DECELERATION SENSOR (When not
Using Intelligent Tester)
NOTICE:
• While obtaining the zero point, do not vibrate the
vehicle by tilting, moving or shaking it and keep it
stationary. (Do not start the engine.)
• Perform this on a level surface (with an inclination
of less than 1
).
(a) Procedures for Test Mode.
(1) Turn the ignition switch OFF.
(2) Using SST, connect terminals 12 (TS) and 4
(CG) of the DLC3.
SST 09843-18040
(3) Check that the shift lever is in the P position and
apply the parking brake.
NOTICE:
DTCs C1210/36 and C1336/39 will be
recorded if the shift lever is not the P
position (see page BC-88).
(b) Obtain the zero point of the yaw rate and
deceleration sensor.
(1) Turn the ignition switch ON.
(2) Keep the vehicle stationary on a level surface for
2 seconds or more.

(8) Check that the ABS warning light and VSC
warning light blink as shown in the illustration.
HINT:
If the ABS warning light and VSC warning
warning light do not blink, check the TS and CG
terminal circuit, and ABS and VSC warning light
circuits.
(9) Start the engine.
(b) w/ 16-inch disc only:
Check the lost booster pressure judgment and
perform the master cylinder pressure sensor zero
point calibration.
NOTICE:
Preform the check in the lost booster pressure
state (negative pressure in the booster is
depressurized).
(1) Turn the ignition switch ON.
(2) Check that the brake warning light comes on
when depressing the brake pedal with a force of
59 N (6 kgf, 13.2 lbf) or more for 1 second or
more. (The lost booster pressure state is judged
normal.)
(3) Start the engine depressing the brake pedal with
a force of 59 N (6 kgf, 13.2 lbf) or more for 1
second or more.
(4) Check that the brake warning light goes off when
quickly releasing the brake pedal. (The lost
booster pressure state is judged normal.)
(5) Leave the vehicle for 1 second or more. (Master
cylinder pressure sensor zero point calibration.)
NOTICE:
• If you slowly depress the brake pedal or
depress it again, master cylinder pressure
sensor zero point calibration is not
performed normally.
• If the lost booster pressure judgment
check is not completed normally, the
master cylinder pressure sensor check is
not judged.
• If a recheck is performed after the engine
has started, end the Test Mode, enter Test
Mode again, and release the vacuum in
the booster by pumping the brake pedal
prior to the recheck.

2. CHECK SENSOR SIGNAL BY TEST MODE (When not
Using Intelligent Tester)
(a) Procedures for test mode:
(1) Turn the ignition switch OFF.
(2) Check that the steering wheel is in the centered
position.

(5) Turn the ignition switch ON.
(6) Check that the ABS warning light and VSC
warning light blink as shown in the illustration.
HINT:
If the ABS warning light and VSC warning
warning light and multi information display and
master caution indicator light do not blink, check
the TS and CG terminal circuit, and ABS and
VSC warning light circuits.
(7) Start the engine.
(b) w/ 16-inch disc:
Check the lost booster pressure judgment and
perform the master cylinder pressure sensor zero
point calibration.
NOTICE:
Preform the check in the lost booster pressure
state (negative pressure in the booster is
depressurized).
(1) Turn the ignition switch ON.
(2) Check that the BRAKE warning light comes on
when depressing the brake pedal with a force of
59 N (6 kgf, 13.2 lbf) or more for 1 second or
more. (The lost booster pressure state is judged
normal.)
(3) Start the engine depressing the brake pedal with
a force of 59 N (6 kgf, 13.2 lbf) or more for 1
second or more.
