PRECAUTION
Note. Some systems need to be initialized after reconnecting the negative (-) battery terminal (See INITIALIZATION ).

INITIALIZATION
- INITIALIZE POWER WINDOW REGULATOR MOTOR FRONT LH NOTE: If the power window motor or power window regulator assembly is replaced, initialization is required (initialization is not necessary when the negative battery terminal is disconnected and reconnected). No other electrical systems should be operated during initialization. Initialization will be interrupted if a voltage drop occurs in the power being supplied to the power window motor. Replacing the door glass or door glass run may cause a difference to exist between the current door glass position and the position memorized in the ECU. In this case, the jam protection function may work improperly. Return the system to the pre-initialized condition and reinitializes the system. HINT: The AUTO UP function will not work unless initialization is completed. The indicator on the power window master switch will blink when the engine switch is on (IG), until initialization has been completed. The indicator will remain on after initialization is successfully completed. Connect the negative battery terminal. Turn the engine switch on (IG). The indicator on the power window master switch will blink. Fully close the door glass by operating the power window master switch. After the door glass stops, hold the power window master switch in the AUTO UP position for 1 second or more. Check that the indicator on the power window master switch remains on. HINT: If the indicator does not remain on, this means that initialization has not been completed successfully. In this case, lower the door glass at least 50 mm (1.96 in.) and hold the power window master switch in the AUTO UP position for 1 second after the window closes fully.
- TO RETURN THE SYSTEM TO THE PRE-INITIALIZED CONDITION Disconnect the power window regulator motor connector during power window operation. This will return the motor to the pre-initialized condition.
FAIL-SAFE CHART
- POWER WINDOW OPERATION IN FAIL-SAFE MODE HINT: If the pulse sensor built into the power window regulator motor (on the driver side) malfunctions, the power window control system enters fail-safe mode. FAIL DETECTION CONDITION CHART Fail mode Fail Detection Condition Pulse direction error With the door glass going up or down, the pulse that indicates door glass operation in the opposite direction is detected for 400 msec. Pulse stop error With the door glass going up or down, no pulse is detected for 350 to 450 msec. The power window control system prohibits the following power window operation when the pulse sensor for the jam protection function has problems and the window position or the learned value is abnormal. Power window control system POWER WINDOW OPERATION CHART Power window operation Engine switch on (IG) Key-off (Within approx. 45 seconds after engine switch turned off) Key-off (After approx. 45 seconds elapsed after engine switch turned off) Manual UP Operation prohibited Operation prohibited Operation prohibited Manual DOWN Operative (Jam protection not operative) Operation prohibited Operation prohibited AUTO UP (hold switch at AUTO UP position) Operative (in MANUAL mode) (Jam protection not operative) Operation prohibited Operation prohibited AUTO UP Operation prohibited Operation prohibited Operation prohibited AUTO DOWN Operation prohibited Operation prohibited Operation prohibited HINT: When the pulse sensor is normal, the AUTO UP/ DOWN function can be resumed by deactivating fail-safe mode. To deactivate fail-safe mode, pull up the driver door power window switch to the AUTO UP position and hold it for at least 1 second to fully close the window from the fully open position. If the LIN communication system malfunctions (communication blackout), the power window control system prohibits the following operations. LIN communication system POWER WINDOW OPERATION CHART Power window operation Engine switch on (IG) MANUAL UP Operative (Jam protection operative) MANUAL DOWN Operative (Jam protection not operative) AUTO UP (hold switch at AUTO UP position) Operative (Jam protection operative) AUTO UP Operative (Jam protection operative) AUTO DOWN Operative (Jam protection not operative)
Note. Some systems need to be initialized after reconnecting the negative (-) battery terminal (See INITIALIZATION ).
