CALIBRATION
1. DESCRIPTION
(a) After replacing any VSC related components or performing wheel alignment adjustment, clear and read the sensor calibration data.
Refer to the table below and then perform the necessary operation according to the part to be replaced in order to perform calibration.
Parts to be Replaced / Operation |
Necessary Operation |
---|---|
Skid control ECU (brake actuator assembly) |
Perform yaw rate and acceleration sensor zero point calibration and store system information. |
Yaw rate and acceleration sensor (airbag sensor assembly) |
|
Wheel alignment adjustment |
|
2. PERFORM YAW RATE AND ACCELERATION SENSOR ZERO POINT CALIBRATION AND STORE SYSTEM INFORMATION (When Using Techstream)
NOTICE:
(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) Connect the Techstream to the DLC3.
(5) Turn the ignition switch to ON.
(6) Turn the Techstream on.
(7) Select the skid control ECU (brake actuator assembly) to clear the zero point calibration data using the Techstream.
Enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Reset Memory.
(8) Check that the slip indicator light comes on.
(9) Turn the ignition switch off.
NOTICE:
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.
(b) Perform the yaw rate and acceleration sensor zero point calibration and store system information.
NOTICE:
Performing the following procedure will perform the yaw rate and acceleration sensor zero point calibration and store 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.
NOTICE:
(4) Connect the Techstream to the DLC3.
(5) Turn the ignition switch to ON.
(6) Turn the Techstream on.
(7) Switch the skid control ECU (brake actuator assembly) to Test Mode using the Techstream.
Enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Test Mode.
(8) After the Test Mode has been entered, keep the vehicle stationary on a level surface for 5 seconds or more.
(9) Check that the slip indicator light comes on for several seconds and then blinks in the Test Mode pattern.
HINT:
(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:
(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.
SST: 09843-18040

(6) Check that the slip indicator light comes on.
NOTICE:
(7) Turn the ignition switch off.
(b) Perform the yaw rate and acceleration sensor zero point calibration and store system information.
NOTICE:
Performing the following procedure will perform the yaw rate and acceleration sensor zero point calibration, and also store 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.
NOTICE:
(4) Using SST, connect terminals 12 (TS) and 4 (CG) of the DLC3.

Immobiliser System does not Operate Properly
DESCRIPTION
The engine immobiliser system compares the ID code that is registered in the
certification ECU (smart key ECU assembly) with the ID code of the transponder chip
that is embedded in the electrical key transmitter sub-assembly.
