INTRODUCTION: REPAIR INSTRUCTION: INITIALIZATION

INITIALIZATION - Continued


11. PERFORM INITIALIZATION OF LINEAR SOLENOID VALVE AND CALIBRATION (When not Using Techstream) (Electronically Controlled Brake System)
(a) Clear the stored value of linear solenoid valve and calibration data.
(1) Turn the power switch off.
(2) Check that the steering wheel is in the straight-ahead position.
(3) Check that the shift lever is in P.
(4) Turn the power switch on (IG) with the brake pedal released.





(5) Using SST, connect and disconnect terminals TS and CG of the DLC3 4 times or more within 8 seconds.
SST: 09843-18040
(6) 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: The ABS warning, brake warning / yellow (minor malfunction) and master caution indicator (VSC warning) light do not indicate a normal system code.
(7) Remove SST from the terminals of the DLC3.
(8) Perform the initialization of linear solenoid valve and calibration.
(9) Perform the zero point calibration of yaw rate and acceleration sensor. Calibration
(b) Perform the initialization of linear solenoid valve and calibration.
(1) Turn the power switch off.
(2) Check that the steering wheel is in the straight-ahead position.
(3) Check that the shift lever is in P.





(4) Using SST, connect terminals TS and CG of the DLC3.
SST: 09843-18040
(5) Turn the power switch on (IG) with the brake pedal released.
NOTICE:
- If the linear solenoid valve offset learning is performed without turning the power switch on (IG), the learning process may not be completed properly because of insufficient auxiliary battery voltage.
- When the linear solenoid valve offset learning is interrupted, or the learning process is performed with the shift lever not in P, DTC 66 (linear solenoid valve offset learning undone) will be stored.
(6) Leave the vehicle stationary without depressing the brake pedal for 1 or 2 minutes.





(7) Check that the interval between blinks of the brake warning light / yellow (minor malfunction) changes from 1 second to 0.25 seconds.

HINT:
- The time needed to complete initialization of linear solenoid valve and calibration varies depending on the auxiliary battery voltage.
- The brake warning light / yellow (minor malfunction) blinks at 1 second intervals during initialization of linear solenoid valve and calibration and changes to the Test Mode display.
- The brake warning light / yellow (minor malfunction) blinks at 0.25 seconds intervals if Test Mode is normal.
(8) Check that DTC 66 (linear solenoid valve offset learning undone) which indicates trouble with stroke sensor zero point learning is not output when the brake warning light / yellow (minor malfunction) changes to the Test Mode display upon initialization of linear solenoid valve and calibration completion.
(9) Turn the power switch off and disconnect the SST from the DLC3.
12. OBTAIN ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (When Using Techstream) (Electronically Controlled Brake System)
NOTICE:
- While obtaining the zero points, 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 in the straight-ahead position.
(3) Check that the shift lever is in P.

(8) Turn the power switch off.
NOTE: If the power switch is turned on (IG) for more than 15 seconds with the shift lever in P after the zero points of the yaw rate and acceleration sensor have 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 will store the zero point calibration for the acceleration sensor as not being completed. The skid control ECU will then also indicate this as a malfunction of the VSC system using the indicator light.

(b) Perform the zero point calibration of the yaw rate and acceleration sensor.
(1) Turn the power switch off.
(2) Check that the steering wheel is in the straight-ahead position.
(3) Check that the shift lever is in P.

(9) Check that the ABS warning, brake warning / yellow (minor malfunction) and master caution indicator (VSC warning) lights come on for several seconds and then blink in Test Mode.

HINT:
- If the ABS warning, brake warning / yellow (minor malfunction) and master caution indicator (VSC warning) lights do not blink, perform zero point calibration again.
- The zero point calibration is performed only once after the system enters Test Mode.
- Calibration cannot be performed again until the stored data is cleared.

(10) Turn the power switch off and disconnect the Techstream.
13. OBTAIN ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (When not Using Techstream) (Electronically Controlled Brake System)

14. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR ASSEMBLY (ON DRIVER SIDE)) (Power Window Control System)
NOTICE:
- DTC B2313 will be set if the driver side power window regulator motor assembly is replaced with a new assembly. Clear the DTC after initializing the power window motor.
- Initialization should be made when the vehicle is stationary.
- Be sure to initialize the door glass position memory (pulse sensor) after replacing the driver side power window regulator motor assembly. Without the initialization, the driver door auto up-and-down function, jam protection function and key-off operation will not work.
- Be sure not to tap or give any shock or force to the door glasses during the initialization procedure as the vehicle is learning the door glasses' sliding resistance during initialization.
- After replacing the driver side power window regulator, door glass, or glass adhesive dams, be sure to initialize the door glass position memory (pulse sensor). Otherwise, the jam protection function may work when unnecessary.

If the initialization procedure cannot be completed normally, there may be a malfunction in the Local Interconnect Network (LIN) communication. Check the body multiplex (LIN) communication system.
(a) Inspection procedure





HINT:
- *1: Even if the door glass has been fully opened before procedure No. 3, it is necessary to press the power window switch down for at least 1 second.
- *2: As soon as the switch is pulled completely up (automatic closing), the master switch indicator starts to blink.
- *3: If the master switch indicator does not come on after procedure No. 4, restart from procedure No. 3.
- *4: Allow the automatic operation to continue without stopping until the door glass is fully closed.
Check the body multiplex LIN system LIN Communication System.
15. RESET BACK DOOR CLOSE POSITION (Power Back Door System)
(a) When disconnecting the cable from the battery terminal, fully close the back door to turn off the courtesy switch.
HINT: If the back door is closed when disconnecting the cable from the battery terminal, it is not necessary to reset it.

16. INITIALIZE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (Sliding Roof System)
NOTE: Be sure to initialize the sliding roof drive gear (pulse sensor) after adjusting the sliding roof glass position or removing and installing components. Without initialization, there may be a malfunction in the sliding roof auto operation, or key-off operation.
