NO. 1 DOOR GLASS DOES NOT MOVE UP AND DOWN IN AUTOMATIC MODE

B3E090358000W06

  Note

  • Perform the following inspection for the power window system component parts of windows where the door glass cannot be operated automatically.

1 | Door glass does not move up and down in automatic mode

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 3-6
• 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 7-11

  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.

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT WHETHER POWER WINDOW SWITCH ENTERS FAIL-SAFE MODE OR NOT • Did the door glass move up or down in automatic mode? | Yes | Reinspect malfunction symptoms.
No | Go to the next step. (Power window switch may enter fail-safe mode.)

2

VERIFY WHETHER MALFUNCTION IS IN WIRING HARNESS (BETWEEN POWER WINDOW SWITCH AND POWER WINDOW MOTOR) OR ELSEWHERE
• Turn the ignition switch to the ON position.
• Inspect the voltage at the following power window switch terminals (sensor 1 signal):

  - Driver's side: G
  - Except driver's side: A

• Does the voltage alternate between 0 V and approx. 12 V when the door glass is moving up and down?

Yes

Go to Step 7.

No | Go to the next step.

3

VERIFY SENSOR 1 OUTPUT SIGNAL
• Turn the ignition switch to the ON position.
• Inspect the voltage at the following power window motor terminals (sensor 1 signal):

  - Front: A
  - Rear: B

• Is the voltage alternate between 0 V and approx. 12 V when the door glass is moving up and down in manual mode?

Yes

Go to the next step.

No | Replace the power window motor, then go to Step 12.

4

INSPECT WIRING HARNESS BETWEEN POWER WINDOW SWITCH AND POWER WINDOW MOTOR FOR CONTINUITY
• Turn the ignition switch to the LOCK position.
• Disconnect the power window switch connector.
• Is there continuity between the following power window switch terminals and power window motor terminals?

  - Driver's side:

  • G-A (sensor 1 signal)
  • C-D (sensor power supply)
  • I-C (ground signal)

  - Passenger's side:

  • A-A (sensor 1 signal)
  • I-D (sensor power supply)
  • G-C (ground signal)

  - Rear side:

  • A-B (sensor 1 signal)
  • I-D (sensor power supply)
  • G-C (ground signal)

Yes

Go to the next step.

No | Repair the wiring harness between the power window switch and power window motor, then go to Step 12.

5

VERIFY WHETHER MALFUNCTION IS IN WIRING HARNESS (BETWEEN POWER WINDOW SWITCH AND POWER WINDOW MOTOR) OR POWER WINDOW SWITCH
• Turn the ignition switch to the ON position.
• Inspect the voltage at the following power window switch terminals:

  - Driver's side

  • G (sensor 1 signal)
  • I (ground signal)

  - Except driver's side

  • A (sensor 1 signal)
  • G (ground signal)

• Is the voltage approx. 12 V?

Yes

Repair the wiring harness between the power window switch and power window motor, then go to Step 12.

No | Replace the power window switch (open circuit or short to power supply in power window switch).

6

VERIFY WHETHER MALFUNCTION IS IN WIRING HARNESS (BETWEEN POWER WINDOW SWITCH AND POWER WINDOW MOTOR) OR ELSEWHERE
• Is there continuity between the following power window switch terminals (wiring harness-side) and ground?

  - Driver's side

  • G (sensor 1 signal)
  • C (sensor power supply)

  - Except driver's side

  • A (sensor 1 signal)
  • I (sensor power supply)

Yes

Replace the wiring harness between the power window switch and power window motor, then go to Step 12.

No | Go to the next step.
7 | VERIFY WHETHER MALFUNCTION IS IN POWER WINDOW SWITCH OR ELSEWHERE • Turn the ignition switch to the ON position. • Inspect the voltage at power window switch terminal E (sensor 2 signal). • Does the voltage alternate between 0 V and approx. 12 V when the door glass is moving up and down? | Yes | Replace the power window switch (malfunction in power window switch automatic mode control), then go to Step 11.
No | Go to the next step.
8 | VERIFY SENSOR 2 OUTPUT SIGNAL • Turn the ignition switch to the ON position. • Inspect the voltage at power window motor terminal B (sensor 2 signal). • Does the voltage alternate between 0 V and approx. 12 V when door glass is moving up and down? | Yes | Go to the next step.
No | Replace the power window motor, then go to Step 12.

9

VERIFY WHETHER MALFUNCTION IS IN WIRING HARNESS (BETWEEN POWER WINDOW SWITCH AND POWER WINDOW MOTOR) OR ELSEWHERE
• Turn the ignition switch to the LOCK position.
• Disconnect the power window switch connector and power window motor connector.
• Is there continuity between the power window switch terminal E (sensor 2 signal) and power window motor terminal B (sensor 2 signal)?

Yes

Go to the next step.

No | Repair the wiring harness between the power window switch and power window motor, then go to Step 12.
10 | VERIFY WHETHER MALFUNCTION IS IN WIRING HARNESS (BETWEEN POWER WINDOW SWITCH AND POWER WINDOW MOTOR) OR ELSEWHERE • Is there continuity between power window switch terminal E (sensor 2 signal) and ground? | Yes | Repair the wiring harness between the power window switch and power window motor, then go to Step 12.
No | Go to the next step.

11

VERIFY WHETHER MALFUNCTION IS IN WIRING HARNESS (BETWEEN POWER WINDOW SWITCH AND POWER WINDOW MOTOR) OR POWER WINDOW SWITCH
• Turn the ignition switch to the ON position.
• Measure the voltage at power window switch terminal E (sensor 2 signal).
• Is the voltage approx. 12 V?

Yes

Repair the wiring harness between the power window switch and front driver-side power window motor, then go to the next step.

No | Replace the power window switch (open circuit or short to power supply/ground in power window switch), then go to the next step.
12 | REINSPECT MALFUNCTION SYMPTOM AFTER REPAIR • Is malfunction no longer present? | Yes | • Troubleshooting completed. • Explain repairs to the customer.
No | Reinspect malfunction symptoms, then repeat from Step 1 if malfunction recurs.
