1. LIGHTING SYSTEM (AFS ECU Initialization)
NOTE: Steering neutral point automatic correction (AFS ECU INITIALIZATION) is necessary under the following condition.
- Disconnecting the battery.
- Replacing the steering sensor or AFS ECU.
a. Run the vehicle on the place where few curve or traffic congestion exist at least 100 m at the speed between 20 km/h (12 mph) and 80 km/h (48 mph).
HINT:
- Steering neutral point correction begins automatically when starting the engine immediately after installing the battery.
- Steering neutral point correction is automatically performed by vehicle running. AFS operation is prohibited when steering neutral point automatic correction is not performed or during automatic correction.
- AFS operation restarts when steering neutral point automatic correction is completed normally.
2. LIGHTING SYSTEM (AFS ECU Re-initialization (When Not Using Intelligent Tester))
NOTE: This operation manually initializes the steering sensor when AFS operation is not normal due to abnormal automatic correction after completion of AFS INITIALIZATION.
HINT:
- If it is necessary to initialize the steering sensor when not disconnecting the battery, it is also possible to re-set the signal from the steering sensor.
- When the centering point memorized in the steering sensor differs from the normal point, the AFS ECU malfunctions. In the case, re-initialize it.
- If the operation does not finish within a specified time period, the system goes off the AFS indicator light and starts steering neutral point automatic correction.
3. LIGHTING SYSTEM (AFS ECU Re-initialization (When Using Intelligent Tester))
NOTE: This operation manually initializes the steering sensor when AFS operation is not normal due to abnormal automatic correction after completion of AFS INITIALIZATION.
HINT:
- If it is necessary to initialize the steering sensor when not disconnecting the battery, it is also possible to reset the signal from the steering sensor.
- When the centering point memorized in the steering sensor differs from the normal point, the AFS ECU malfunctions. In the case, re-initialize it.
- If the operation does not finish within a specified time period, the system goes off the AFS indicator light and starts steering neutral point automatic correction.
a. Connect the intelligent tester to the DLC3.
b. Turn the ignition switch to the ON position and press the intelligent tester main switch ON.
c. Select "STEER SENS INIT" on "DIAGNOSTICS MENU AFS" display.
d. Turn the steering wheel with the engine starting until the tires face straight ahead, and press "ENTER".
e. Check "CONFIRM" display and press "YES".
NOTE: Do not turn the steering wheel while initializing and keep the tires facing straight ahead.
f. Check the display for completion of the operation.
HINT: If the operation above cannot be completed after several attempts, a malfunction in the steering sensor circuit is suspected.
4. POWER DOOR LOCK CONTROL SYSTEM
BACK DOOR LOCK
a. When the battery is reconnected:
If the back door is locked and therefore cannot be opened, it is necessary to unlock the back door using the door control switch or transmitter switch.
b. When the back door lock is replaced:
The power back door ECU cannot receive a switch signal from the lock. This may cause the power back door system to enter fail-safe mode and DTC B2215 to set, as well as to make the system disabled. When the lock is replaced, be sure to perform the following: first properly connect the lock, second clear the DTC from memory using the intelligent tester and finally recheck that no DTC is output.
5. POWER WINDOW CONTROL SYSTEM
RESET (INITIALIZE) POWER WINDOW REGULATOR MOTOR
NOTE:
- Resetting the power window motor (initializing the pulse sensor) is necessary when the battery terminal is disconnected; when the power window regulator master switch, power window regulator switch, wire harness, power window regulator and power window motor are replaced or removed/ installed; or when the fuses are replaced. AUTO operation function, jam protection function and remote operation function via the power window regulator master switch do not operate without resetting.
- Be sure to reset the power window regulator motors using the power window switch on each door because the motors cannot be reset by remote operation using the power window master switch.
- In order to prevent a large amount of current from flowing in the wires, do not simultaneously reset 2 or more power window regulator motors.
- If the power window switch has been continuously operated for a long time, the power window regulator motor will stop so that no additional load will be applied to the motor.
Continuing to operate the switch even after the motor has stopped will cause the switch to blink while restricting the AUTO UP/DOWN function and the remote UP/DOWN function. If this happens, reset the motor again after several minutes have passed.
- Whenever disconnecting the battery terminal, reset all the other systems besides the power window control system.
a. Turn the ignition switch ON.
b. Halfway open the power window by pressing the power window switch.
c. Fully pull up the switch until the power window is fully closed and continue to hold the switch for approx. 1 second after the power window is fully closed.
d. Check that the AUTO UP/DOWN function operates normally.
If the AUTO UP/DOWN function operates normally, reset operations have been completed at this time. If not normal, follow steps below.
1. Disconnect the negative battery terminal for 10 seconds.
2. Connect the battery terminal.
3. Turn the ignition switch ON.
4. Halfway open the power window by pressing the power window switch.
5. If the AUTO UP/DOWN function operates normally, reset operations have been completed at this time.
If not normal, follow steps below.
6. Turn the ignition switch ON.
7. Halfway open the power window by pressing the power window switch.
8. Fully pull up the switch until the power window is fully closed and continue to hold the switch for approx. 12 seconds after the power window is fully closed.
9. Check that the AUTO UP/DOWN function operates normally.
6. POWER BACK DOOR SYSTEM (Reset (Initialize))
a. Resetting the power back door system:
The power back door ECU records the fully open position and the fully closed position of the power back door in its memory and the power back door fully opens and fully closes based on this memory. In the case where any of the batteries, fuses, power back door ECU or power back door drive unit are removed and then reinstalled, the power back door ECU loses the memory of the door positions. In such cases, resetting the system is necessary. However, the back door closer system has no effect on ECU memory.
Reset the power back door system as follows:
1. Fully close the power back door if opened.
2. Check that the back door fully opens and fully closes.
- Unlock the power back door using the unlock button on the transmitter switch or the door control switch.
- Turn the ignition switch to the off.
- Check that the power back door main switch is not pushed.
- Check that the back door fully opens and fully closes by pushing the power back door opener/closer switch or PWR button on the transmitter switch.
HINT: The jam protection function is enabled through the above initialization procedure.
7. POWER BACK DOOR SYSTEM (Back Door Lock)
a. When the battery is reconnected:
If the back door is locked and therefore cannot be opened, it is necessary to unlock the back door using the door control switch or transmitter switch.
b. When the back door lock is replaced:
The power back door ECU cannot receive a switch signal from the lock. This may cause the power back door system to enter fail-safe mode and DTC B2215 to set, as well as make the system disabled. When the lock is replaced, be sure to perform the following: first, properly connect the lock, second clear the DTC from memory using the intelligent tester, and finally recheck that no DTC is output.
8. SLIDING ROOF SYSTEM (for Multi-panel Moon Roof)
RESET SLIDING ROOF MOTOR
a. The sliding roof may not operate automatically and the jam protection function will not function correctly after you reconnect, replace or recharge the battery. In any of these cases, reset the sliding roof system using method.
1. Press the sliding roof switch on SLIDE CLOSE or TILT DOWN side and hold it. When the roof glass stops at the fully closed position for 1 second, the reset of the motor is completed.
HINT: If the battery terminal is disconnected, the ECU of the sliding roof motor may not detect the position of the roof glass. If the AUTO operation function is still disabled even after the sliding roof motor is reset, the Hall IC (built in the sliding roof motor assembly) for detecting the roof glass position may be malfunctioning.
9. SLIDING ROOF SYSTEM (for Standard)
RESET SLIDING ROOF MOTOR
a. The sliding roof may not operate automatically and the jam protection function will not function correctly after you reconnect, replace or recharge the battery. In any of these cases, reset the sliding roof system using method.
1. Push and hold the slide switch toward the front or tilt switch on the rear side.
2. Check that the sliding roof will tilt up and down, or slide open and close.
3. After the slide operation, release the switch.
4. Make sure that the sliding roof opens and closes automatically.
HINT: If the battery terminal is disconnected, the ECU of the sliding roof motor may not detect the position of the roof glass. If the AUTO operation function is still disabled even after the sliding roof motor is reset, the hall IC (built in the sliding roof motor assembly) for detecting the roof glass position may be malfunctioning.
