Right Rear Power Window Switch Input Test
NOTE:
- Before testing, make sure the No. E3 (20 A) fuse in the passenger's under-dash fuse/relay box is OK.
- Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.
1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the right rear power window switch 14P connector
.
3. Inspect the connector and socket terminals to be sure they are all making good contact:
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals are OK, go to step 4.
4. With the connector still disconnected, do the following input tests:
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 5.
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 1.2 | LT BLU.LT GRN | Under all conditions | Connect terminals No. 1 and No. 4, and terminals No. 2 and No. 3 with jumper wires: The right rear power window should close. |
|
| Under all conditions | Connect terminals No. 2 and No. 4, and terminals No. 1 and No. 3 with jumper wires: The right rear power window should open. |
|||
| 14 | GRN | Disconnect the right rear power window motor 6P connector. | Check for continuity between terminal No. 14 and right rear power window motor 6P connector terminal No. 4: There should be continuity. | An open or high resistance in the wire |
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 11 | BLU | Disconnect these connectors:
|
Check for continuity between terminal No. 11 and power window master switch 37P connector terminal No. 36: There should be continuity. |
An open in the LIN(P/W) wire |
| Check for continuity between terminal No. 11 and front passenger's power window switch 37P connector terminal No. 34: There should be continuity. |
An open in the LIN(P/W) wire | |||
| Check for continuity between terminal No. 11 and left rear power window switch 14P connector terminal No. 11: There should be continuity. |
An open in the LIN(P/W) wire | |||
| Check for continuity between terminal No. 11 and moonroof control unit/motor 14P connector terminal No. 12: There should be continuity. |
An open in the LIN(P/W) wire | |||
| Check for continuity to ground: There should be no continuity. | A short to ground in the LIN(P/W) wire |
5. Reconnect the connector, and do the following input tests:
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, replace the right rear power window switch .
NOTE: After replacing the left rear power window switch, do the resetting the power window control unit .
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 4 | GRN | Under all conditions | Measure the voltage to ground: There should be battery voltage. |
|
| 3 | BLK | In all power modes | Measure the voltage to ground: There should be less than 0.2 V. |
|
| 10 | PUR | Turn the vehicle to the ON mode. | Measure the voltage to ground: There should be battery voltage. |
|
| 13 | RED | Turn the vehicle to the ON mode, and right rear power window moving up or down | Measure the voltage between terminals No. 13 and No. 3: An analog meter should alternate between 0 V and 5 V (a digital voltmeter should read about 2.5 V while the window moves). |
|
| 12 | YEL | Turn the vehicle to the ON mode, and right rear power window moving up or down | Measure the voltage between terminals No. 12 and No. 3: An analog meter should alternate between 0 V and 5 V (a digital voltmeter should read about 2.5 V while the window moves). |
