Power Mirrors (Front Passenger's Power Window Switch)
NOTE:
- Before testing, make sure the No. B44 (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 front passenger's power window 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 |
|---|---|---|---|---|
| 11 . 12 |
BLU . RED |
Connect terminals No. 4 and No. 12 (or No. 11), and terminals No. 11 (or No. 12) and No. 3 with jumper wires. | Check the right power mirror operation: The right power mirror should move LEFT (or RIGHT). |
|
| 12 . 13 |
RED.PUR | Connect terminals No. 4 and No. 13 (or No. 12), and terminals No. 12 (or No. 13) and No. 3 with jumper wires. | Check the right power mirror operation: The right power mirror should move UP (or DOWN). |
|
| 15 | GRY | Connect terminals No. 4 and No. 15 with a jumper wire | Check the right power mirror defogger operation: The right power mirror defogger should work (the inside lower edge becomes warm). |
|
| 34 | RED | Disconnect the power window master switch 37P connector and the moonroof control unit/motor 14P connector | 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 |
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 .
NOTE:
After replacing the front passenger's 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. |
