- The initialization procedures are show below the table.
1. LIGHTING SYSTEM (AFS ECU INITIALIZATION)
NOTICE:
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 TECHSTREAM))
NOTICE:
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.
1. SHIFT TO INITIALIZATION
(a) Engine is running and shift range is in the P position.
(b) Press the AFS OFF switch eight times at approximately one-second interval (once for ON and once more for OFF, i.e. 4 times ON and 4 times OFF).
HINT:
- The AFS OFF indicator light starts to blink twice per second.
- Initialization can be started when the AFS OFF switch is either in the "ON" or "OFF" position.
- When the AFS OFF switch is pressed eight times, it will return to its original state.
NEXT -- Continue to next step.
2. INITIALIZATION OF AFS ECU
(a) Turn the steering wheel to adjust the tires so that they point straight ahead.
(b) Do not change the steering wheel position. Press the AFS OFF switch twice (once ON and once OFF).
HINT:
- The AFS OFF indicator light stays lit for two seconds.
- When the AFS OFF switch is pressed twice, it will return to its original state.

Result:
HINT:
- Failure to complete initialization. Proceed to step 2 within 10 seconds.
- If 10 seconds elapse, the system starts steering neutral point automatic correction.
B -- GO TO STEP 2
A -- END
3. LIGHTING SYSTEM (AFS ECU RE-INITIALIZATION (WHEN USING TECHSTREAM))
NOTICE:
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.

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 Techstream and finally recheck that no DTC is output.
5. POWER WINDOW CONTROL SYSTEM
RESET (INITIALIZE) POWER WINDOW REGULATOR MOTOR
NOTICE:
- 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.

When the lock is replaced, be sure to perform the following: first properly connect the lock, second clear the DTC from memory using the Techstream and finally recheck that no DTC is output.
7. BACK DOOR CLOSER 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) Activate the transmitter switch or power back door opener/closer switch to open the power back door.
(3) Check that the drive unit for the power back door stops operating at a predetermined position and that the damper stay allows the back door to move to the fully open position from the position where the drive unit stops. The power back door ECU records the fully open position at this time and the system has been reset.
8. 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.
