Calibration








BRAKE CONTROL: ELECTRONICALLY CONTROLLED BRAKE SYSTEM: CALIBRATION

CALIBRATION

1. DESCRIPTION

- After replacing the VSC relevant components or performing "Front wheel alignment adjustment", clear and read the sensor calibration data.
- Follow the chart to perform calibration.





2. PERFORM ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (TECHSTREAM)
NOTICE:
- While obtaining the zero point, keep the vehicle stationary and do not vibrate, tilt, move, or shake it. (Do not turn the power switch on (READY).)
- 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.
(1) Turn the power switch off.
(2) Connect Techstream to the DLC3.
(3) Check that the steering wheel is centered and move the shift lever to the P position.
(4) Turn the power switch on (IG).
(5) Operate Techstream to erase the codes (select "Reset Memory").
HINT: Refer to the Techstream operator's manual for further details.
(6) Turn the power switch off.
(b) Perform zero point calibration of the yaw rate and acceleration sensor.
(1) Turn the power switch off.
(2) Check that the steering wheel is centered and move the shift lever to the P position.
NOTICE: DTCs C1210/36 and C1336/98 will be recorded if the shift lever is not in the P position C1210.
(3) Connect Techstream to the DLC3.
(4) Turn the power switch on (IG).
(5) Set Techstream to Test Mode (select "Test Mode").
HINT: Refer to the Techstream operator's manual for further details.
(6) After the Test Mode has been entered, keep the vehicle stationary on a level surface for 2 seconds or more.




(7) Check that the ABS warning, brake control warning and master caution indicator lights blink and a check VSC system message is displayed on the multi information display (Test Mode).
HINT :
- The SLIP indicator remains on during Test Mode because TRAC is prohibited.
- If the ABS warning, brake control warning and master caution indicator lights do not blink and/or a check VSC system message is not displayed on the multi information display, 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.
- Illustrations may differ from the actual screen displayed depending on the specifications of the vehicle and customized settings.
(8) Turn the power switch off and disconnect Techstream.
3. PERFORM ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (SST CHECK WIRE)
NOTICE:
- While obtaining the zero point, keep the vehicle stationary and do not vibrate, tilt, move, or shake it. (Do not turn the power switch on (READY).)
- 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.




(1) Turn the power switch off.
(2) Check that the steering wheel is centered and move the shift lever to the P position.
(3) Turn the power switch on (IG).
(4) Check that the warning light and indicator light come on and remains on until the power switch is turned on (READY).
(5) Turn the power switch on (IG).
(6) Using SST, connect and disconnect terminals TS and CG of the DLC3 4 times or more within 8 seconds.
SST: 09843-18040
(7) Check that no codes other than ABS code 42, VSC code 45 and Electronically Controlled Brake code 48, 66, or 95 are stored in the diagnostic system.




HINT:
- The ABS warning, brake control warning lights, and multi information display do not indicate the normal system code.
- Illustrations may differ from the actual screen displayed depending on the specifications of the vehicle and customized settings.
(8) Remove the SST from the terminals of the DLC3.
(b) Perform zero point calibration of the yaw rate and acceleration sensor.
(1) Turn the power switch off.
(2) Check that the steering wheel is centered and move the shift lever to the P position.
NOTICE: DTCs C1210/36 and C1336/98 will be recorded if the shift lever is not in the P position C1210.




(3) Using SST, connect terminals TS and CG of the DLC3.
SST: 09843-18040
(4) Turn the power switch on (IG).
(5) Keep the vehicle stationary on a level surface for 2 seconds or more.




(6) Check that the ABS warning, brake control warning and master caution indicator lights blink and a check VSC system message is displayed on the multi information display (Test Mode).
HINT :
- The SLIP indicator remains on during Test Mode because TRAC is prohibited.
- If the ABS warning, brake control warning and master caution indicator lights do not blink and/or a check VSC system message is not displayed on the multi information display, 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.
- Illustrations may differ from the actual screen displayed depending on the specifications of the vehicle and customized settings.
(7) Turn the power switch off and disconnect the SST from the DLC3.
