Power Window Master Switch Input Test (2013-18)
NOTE:
- Before testing, make sure the No. B42 (20 A) fuse in the under-dash fuse/relay box is OK.
- Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.
1. Press the engine start/stop button to select the OFF mode.
2. Disconnect the power window master switch 37P 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 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 | 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. |
|
| Connect terminals No. 1 and No. 4, and terminals No. 2 and No. 3 with jumper wires. | Check driver's power window motor operation:The driver's power window should open. | |||
| 36 | WHT | Disconnect the front passenger's power window switch 37P connector and the moonroof control unit/motor 14P connector | 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 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 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. |
|
| 26 | GRN | Under all conditions | Measure the voltage to ground:There should be battery voltage. |
|
| 25 | BRN | Power mode ON | 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. |
|
| 31 | 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. |
|
| 13 | GRY | Power mode ON | Measure the voltage to ground:There should be battery voltage. |
|
| 17 | BLU | Power mode ON, and driver's power window moving up or down | Measure the voltage between terminals No. 17 and No. 31:An analog meter should alternate between 0 V and 5 V(a digital voltmeter should read about 2.5 V while the window moves). |
|
| 19 | GRN | Power mode ON, and driver's power window moving up or down | Measure the voltage between terminals No. 19 and No. 31:An analog meter should alternate between 0 V and 5 V(a digital voltmeter should read about 2.5 V while the window moves). |
