pattern.
HINT:
If the slip indicator light does not blink, perform zero point calibration again.
The zero point calibration is performed only once after the system enters the Test Mode.
Calibration cannot be performed again until the stored data is cleared.
(10) Turn the ignition switch off and disconnect the Techstream.
3. PERFORM YAW RATE AND ACCELERATION SENSOR ZERO POINT CALIBRATION AND STORE
SYSTEM INFORMATION (When Using SST Check Wire)
NOTICE:
S
tored system information cannot be overwritten unless it is cleared. Clear the stored information and then
store new system information.
While obtaining the zero points, keep the vehicle stationary and do not vibrate, tilt, move, or shake it (do
not start the engine).
Be sure to perform this procedure on a level surface (with an inclination of less than 1 degree).
(a) Clear the zero point calibration data and store system information.
NOTICE:
Performing the following procedure will clear the zero points of the yaw rate and acceleration sensor and
system information simultaneously.
(1) Turn the ignition switch off.
(2) Check that the steering wheel is centered.
(3) for Manual Transmission:
Check that the shift lever is in neutral and apply the parking brake.
for Automatic Transmission:
Check that the shift lever is in P and apply the parking brake.
(4) Turn the ignition switch to ON.
(5) Using SST, connect and disconnect terminals 12 (TS) and 4
(CG) of the DLC3 4 times or more within 8 seconds.

(6) Check that the slip indicator light comes on.
NOTICE:
If the vehicle is driven after the zero point of the yaw rate and acceleration sensor and system information
are cleared, DTCs will be stored.
If the ignition switch is turned ON for more than 15 seconds with the parking brake applied*1 or shift lever
in P*2 after the 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 these conditions, the skid control ECU
(brake actuator assembly) will store the zero point calibration for the acceleration sensor as not being
completed. The skid control ECU (brake actuator assembly) will then also indicate this as a malfunction of
the VSC system using the indicator light.
