POWER WINDOW MAIN SWITCH INSPECTION

BME091266350W04

## Driver's side

1. Remove the power window main switch panel.

2. Connect the power window main switch connector.

3. Measure the voltage at the power window main switch terminals as indicated below.

4. Disconnect the power window main switch connector before inspecting for continuity at terminals 1H and 2C.

  • If the parts and wiring harnesses are okay but the system still does not work properly, replace the power window main switch.
  • If not as specified, inspect the parts listed under "Action."

### Terminal voltage table (Reference)

Terminal | Signal | Connected to | Test condition | Voltage (V)/Continuity | Action
--- | --- | --- | --- | --- | ---
1A (1M) | Close output | Power window motor | Door glass is open | Below 1.0 | • Inspect power window motor • Inspect related harness
Door glass is closed | B+
1C (1K) | Open output | Power window motor | Door glass is open | B+ | • Inspect power window motor • Inspect related harness
Door glass is closed | Below 1.0
1F | IG1 | P.WIND 30 A fuse | Ignition switch is at ON position | B+ | • Inspect P.WIND 30 A fuse • Inspect related harness
Ignition switch is at LOCK position | Below 1.0
1H | Ground | GND | Inspect for continuity to ground under any condition | Yes | -
1I | Power supply | ACC.DELAY 30 A fuse | Under any condition | B+ | • Inspect ACC.DELAY 30 A fuse • Inspect related harness
1N | Door switch | Door switch | Any door is open (door switch is on): inspect for continuity to ground | Yes | • Inspect door switch • Inspect related harness
All doors are closed (door switch is off): inspect for continuity to ground | No
2B | Limit switch on/off | Power window motor | Door glass is opened fully (limit switch is on) | 0 | • Inspect power window motor • Inspect related harness
Door glass is closed fully (limit switch is off) | 5
2C | Ground | Power window motor | Inspect for continuity to ground under any condition | Yes | -
2D | Pulse | Power window motor | Door glass is in motion | Alternates between 0 and 5 | • Inspect power window motor • Inspect related harness
Door glass is not in motion | 0 or 5

### Except driver's side

1. Remove the power window main switch.

2. Turn the power-cut switch to UNLOCK.

3. Inspect for continuity between the power window main switch terminals using an ohmmeter.

  • If not as specified, replace the power window main switch.
