Front Passenger's Power Window Switch Input Test (2014)
- Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.
- Before testing, make sure the No. B33 (20 A) fuse in the under-dash fuse/relay box is OK.
1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the front passenger's power window switch 37P connector - Refer to: Front Passenger's Power Window Switch Removal and Installation,
.
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 look 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 |
|---|---|---|---|---|
| 2 1 |
BLU RED |
Connect terminals No. 2 and No. 4, and terminals No. 1 and No. 3 with jumper wires. | Check front passenger's power window motor operation: The front passenger's power window should close. |
|
| Connect terminals No. 1 and No. 4, and terminals No. 2 and No. 3 with jumper wires. | Check front passenger's power window motor operation: The front passenger's power window should open. |
|||
| 27 | BLK | Disconnect the front passenger's power window motor 6P connector | Check for continuity between terminal No. 27 and front passenger's power window motor 6P connector terminal No. 4: There should be continuity. |
An open or high resistance in the wire |
*: With moonroof
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 34 | LT BLU | Disconnect these connectors:
|
Check for continuity between terminal No. 34 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. 34 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 |
*: With moonroof
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 front passenger's power window switch - Refer to: Front Passenger's Power Window Switch Removal and Installation,
| 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. |
|
| 37 | PUR | Turn the vehicle to the ON mode | Measure the voltage to ground: There should be battery voltage. |
|
| 36 | ORN | Turn the vehicle to the ON mode, and front passenger's power window moving up or down | Measure the voltage between terminals No. 36 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). |
|
| 35 | PNK | Turn the vehicle to the ON mode, and front passenger's power window moving up or down | Measure the voltage between terminals No. 35 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). |
