Diagnostic procedure
DOOR GLASS OTHER THAN DRIVER'S DOOR CANNOT BE OPERATED (CANNOT BE OPERATED USING POWER WINDOW MAIN SWITCH BUT CAN BE OPERATED USING EACH SUBSWITCH) - DIAGNOSTIC PROCEDURE
| STEP |
INSPECTION |
ACTION |
| 1 |
- POWER WINDOW MAIN SWITCH CONNECTOR INSPECTION
- Switch the ignition off.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION
.)
- Disconnect the power window main switch connector.
- Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
- Is the connector normal?
|
Yes |
Go to the next step. |
| No |
Repair or replace the connector, then go to Step 4. |
| 2 |
POWER WINDOW SUBSWITCH CONNECTOR INSPECTION
- Disconnect the power window subswitch connector.
- Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
- Is the connector normal?
|
Yes |
Go to the next step. |
| No |
Repair or replace the connector, then go to Step 4. |
| 3 |
POWER WINDOW MAIN SWITCH INSPECTION
- Reconnect all the disconnected connectors.
- Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION
.)
- Measure the voltage at the following power window main switch terminals (vehicle wiring harness). (See POWER WINDOW MAIN SWITCH INSPECTION
.)
- Terminals 1B and 1D if door glass (RF) does not operate
- Terminals 1G and 1I if door glass (LR) does not operate
- Terminals 1A and 1C if door glass (RR) does not operate
- Is the power window main switch voltage normal?
|
Yes |
Refer to the wiring diagram and verify if there is a common connector between the following terminals.
- Power window main switch terminal 1D and power window subswitch (RF) terminal E
- Power window main switch terminal 1B and power window subswitch (RF) terminal B
- Power window main switch terminal 1I and power window subswitch (LR) terminal E
- Power window main switch terminal 1G and power window subswitch (LR) terminal B
- Power window main switch terminal 1C and power window subswitch (RR) terminal E
- Power window main switch terminal 1A and power window subswitch (RR) terminal B If there is a common connector:
- Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an open or short circuit to determine the malfunctioning location.
- Repair or replace the malfunctioning location. If there is no common connector:
- Repair or replace the wiring harness which has an open or short circuit.
Go to the next step. |
| No |
Replace the power window main switch, then go to the next step. (See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION
.) |

VERIFY IF MALFUNCTION CAUSE IS CORRECTED
- Does the power window system operate normally?
|
Yes |
Troubleshooting completed. (Explain the problem to the customer.) |
| No |
Verify the malfunction symptom in the symptom troubleshooting chart and perform the other applicable malfunction diagnosis. |
