INITIALIZATION

1. 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 PWR fuse, RR DOOR LH fuse, RR DOOR RH and ECU-B fuse 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. Turn the ignition switch ON. Halfway open the power window by pressing the power window switch. 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. 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. Disconnect the negative battery terminal for 10 seconds. Connect the battery terminal. Turn the ignition switch ON. Halfway open the power window by pressing the power window switch. If the AUTO UP/DOWN function operates normally, reset operations have been completed at this time. If not normal, follow steps below. Turn the ignition switch ON. Halfway open the power window by pressing the power window switch. 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. Check that the AUTO UP/DOWN function operates normally.

1. DESCRIPTION Data of the system can be read in the Data Link Connector 3 (DLC3) of the vehicle. Therefore, when the system seems to be malfunctioning, use the intelligent tester to check for a malfunction and repair it.
2. CHECK DLC3 The vehicle's ECM uses ISO 9141-2 communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 9141-2 format. Standard TESTER CONNECTION SPECIFIED CONDITION Tester Connection Condition Specified Condition 7 (Bus + line) - 5 (Signal ground) During communication Pulse generation 4 (Chassis ground) - Body ground Constant Below 1 ohms 5 (Signal ground) - Body ground Constant Below 1 ohms 16 (B+) - Body ground Constant 9 to 14 V HINT: If the screen displays a communication error message after you have connected the cable of the intelligent tester to the DLC3, turned the ignition switch ON and used the intelligent tester, the problem may be on the vehicle side or tester side. If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle. If communication is still impossible when the tester is connected to another vehicle, the problem is probably in the tester itself, so consult the Service Department listed in the tester's instruction manual.
3. INSPECT BATTERY VOLTAGE Check the battery voltage. Standard voltage: 11 to 14 V If the voltage is below 11 V, replace the battery before proceeding.
4. CHECK DIAGNOSIS Turn the ignition switch ON. Operate the driver side switch of the master switch. Check the blinking pattern of the AUTO light as shown in the illustration. If pattern (A) is displayed, reset power window regulator motor. If pattern (B) or (C) is displayed, check the wire harness. If the normal pattern is displayed, replace the multiplex network master switch.
