| POSSIBLE CAUSE |
- Open circuit or short to power supply in sensor 1 signal, ground signal from wiring harness (between power window switch and power window motor), inner power window switch, or inner motor: Steps 4-7
- Open circuit or short to power supply/ground in sensor 2 signal from wiring harness (between power window switch and power window motor), inner power window switch, or inner motor: Steps 8-12
NOTE:
- The automatic function and the IG OFF timer function do not operate while the power window switch is in fail-safe mode. The fail-safe operates when sensor 1, and/or sensor 2, and/or the sensor power supply malfunctions.
- Sensor 1 and/or 2 malfunction
- When the door glass is moving up and down, the power window switch cannot sense a pulse signal from sensor 1 during the time it senses 5 pulses (2.5 cycles) from sensor 2.
- When the door glass is moving up and down, the switch cannot sense a pulse signal from sensor 2 during the time it senses 5 pulses (2.5 cycles) from sensor 1.
- There are three abnormal pulses in a pulse signal while the door glass is moving up or down.
- There are 20 cycle pulses from a closed position while the door glass is moving up.
- There is no pulse signal for 1 s after the door glass is moved down.
