Power Window Master Switch Input Test (2/4-door)
NOTE:
- Before testing, make sure the No. A18 (10 A) fuse in the under-hood fuse/relay box is OK.
- Before testing, make sure the No. B9 (10 A), No. B14 (20 A), No. B27 (20 A), and No. B28 (20 A) fuses in the under-dash fuse/relay box are OK.
- Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.
- If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A .
1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the power window master switch 37P connector .
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.
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 |
|---|---|---|---|---|
| 2*1 | YEL*GRN | Connect terminals No. 2 and No. 4, and terminals No. 1 and No. 3 with jumper wires. | Check driver's power window motor operation: The driver's power window should close. |

| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 26 *1*25 *1 | GRN*PUR | Connect terminals No. 26 and No. 4 with a jumper wire. | Check right rear power window motor operation: The right rear power window should close. |
|
| Connect terminals No. 25 and No. 4 with a jumper wire. | Check right rear power window motor operation: The right rear power window should open. | |||
| 36 *1 | WHT | Disconnect these connectors:
|
Check for continuity between terminal No. 36 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. 36 and moonroof motor-control unit 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 | |||
| 36 *2 | WHT | Disconnect these connectors:
|
Check for continuity between terminal No. 36 and 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. 36 and moonroof motor-control unit 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 |

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 power window master switch .
NOTE: After replacing the power window master 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 | WHT | Under all conditions | Measure the voltage to ground: There should be battery voltage. |
|
| 37 | RED | Under all conditions | Measure the voltage to ground: There should be battery voltage. |
|
| 18 | BRN | Vehicle ON mode | Measure the voltage to ground: There should be battery voltage. |
|
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 3 | BLK | In all power modes | Measure the voltage to ground: There should be less than 0.2 V. |
|
| 29 | BLK | In all power modes, disconnect the driver's power window motor 6P connector | Measure the voltage to ground: There should be less than 0.2 V. |
|
| 34 | LT BLU | Vehicle ON mode | Measure the voltage to ground: There should be battery voltage. |
|
| 33 | LT GRN | Vehicle ON mode, and driver's power window moving up or down | Measure the voltage between terminals No. 33 and No. 29: An analog meter should alternate between 0 V and 5 V(a digital voltmeter should read about 2.5 V while the window moves). |
|
| 35 | PNK | Vehicle ON mode, and driver's power window moving up or down | Measure the voltage between terminals No. 35 and No. 29: An analog meter should alternate between 0 V and 5 V (a digital voltmeter should read about 2.5 V while the window moves). |
