Calibration
BRAKE CONTROL: ELECTRONICALLY CONTROLLED BRAKE SYSTEM: CALIBRATION
1. DESCRIPTION
* After replacing the VSC relevant components or performing "Front wheel alignment adjustment", clear and read the sensor calibration data.
* Follow the procedure to perform calibration.
2. CLEAR ZERO POINT CALIBRATION (WHEN USING TECHSTREAM)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Operate the Techstream to erase the codes (select "Reset Memory").
HINT
Refer to the Techstream operator's manual for further details.
3. PERFORM ZERO POINT CALIBRATION OF YAW RATE AND ACCELERATION SENSOR (WHEN USING TECHSTREAM)
NOTICE:
* While obtaining the zero point, do not vibrate the vehicle by tilting, moving or shaking it. Keep it in a stationary condition and do not start the engine.
* Choose a level surface with an inclination of less than 1°.
(a) Procedures for Test Mode.
(1) Ensure that the steering wheel is centered, move the shift lever to the P position, and apply the parking brake.
NOTICE:
DTC C1210/36 and C1336/98 will be recorded if the shift lever is not in the P position.
(2) Connect the Techstream to the DLC3.
(3) Turn the engine switch on (IG).
(4) Set the Techstream to Test Mode (select "Test Mode").
HINT
Refer to the Techstream operator's manual for further details.
(b) Obtain the zero point of the yaw rate and acceleration sensor.
(1) Keep the vehicle stationary on a level surface for 4 seconds or more.
(2) Check that the slip indicator light blinks.
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.
(c) Turn the engine switch off and disconnect the Techstream.
4. CLEAR ZERO POINT CALIBRATION (WHEN USING SST CHECK WIRE)
(a) Turn the engine switch on (IG).
(b) Using SST, connect and disconnect terminals 12 (TS) and 4 (CG) of the DLC3 4 times or more within 8 seconds.
SST : 09843-18040
(c) Check that no codes other than ABS code 42, VSC code 45 and electronically controlled brake system code 48, 66, or 95 are stored in the diagnostic system.
HINT
* When only 1 DTC is stored, the relevant light outputs the same code after an interval of 4 seconds. Example: When DTC 42 is stored, the light blinks 4 times, turns off for 1.5 seconds, blinks twice, turns off for 4 seconds, and then repeats this output pattern.
* When 2 or more DTCs are stored, the relevant light outputs the codes with an interval of 2.5 seconds between each different code, and the output of all codes repeats after an interval of 4 seconds.
* The ABS warning light, slip indicator light and brake warning light / yellow (minor malfunction) do not indicate the normal system code.
5. PERFORM ZERO POINT CALIBRATION OF YAW RATE AND ACCELERATION SENSOR (WHEN USING SST CHECK WIRE)
NOTICE:
* While obtaining the zero point, do not vibrate the vehicle by tilting, moving or shaking. Keep it in a stationary condition and do not start the engine.
* Choose a level surface with an inclination of less than 1°.
(a) Procedures for Test Mode.
(1) Turn the engine switch off.
(2) Using SST, connect terminals 12 (TS) and 4 (CG) of the DLC3.
SST : 09843-18040
(3) Check that the steering wheel is in the centered position and move the shift lever to the P position.
NOTICE:
DTC C1210/36 and C1336/98 will be recorded if the shift lever is not in the P position.
(b) Obtain the zero point of the yaw rate and acceleration sensor.
(1) Turn the engine switch on (IG).
(2) Keep the vehicle in a stationary condition on a level surface for 4 seconds or more.
(3) Check that the slip indicator light blinks.
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.
(c) Turn the engine switch off and disconnect SST from the DLC3.
