Power Sunshade Motor-Control Unit Input Test
- Make sure the fuses associated with the system is OK.
- If the power sunshade works OK manually, but will not work in AUTO, or reverses frequently (obstacle detection), reset the power sunshade motor-control unit before proceeding with the input test.
1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the power sunshade motor-control unit 14P connector.
Power Sunshade Motor-Control Unit 14P Connector (female terminals)
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 connectors 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 |
|---|---|---|---|---|
| 13 | TAN | Disconnect panoramic glass roof motor-control unit 14P connector | Check for continuity between terminal No. 13 and panoramic glass roof motor-control unit 14P connector terminal No. 13: There should be continuity | An open in the SUNSHADE CONTL wire |
| Check for continuity to ground: There should be no continuity. | A short to ground in the SUNSHADE CONTL 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 sunshade motor-control unit .
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 1 | YEL | Under all conditions | Measure the voltage to ground: There should be battery voltage. | An open or high resistance in the wire |
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 4 | BLK | In all power modes | Measure the voltage to ground: There should be less than 0.2 V. |
|
| 9 | YEL | Vehicle ON mode, power sunshade switch in CLOSE position | Measure the voltage to ground: There should be less than 0.2 V. |
|
| Vehicle ON mode, power sunshade switch released | Measure the voltage to ground: There should be battery voltage. |
|
||
| 7 | PNK | Vehicle ON mode, power sunshade switch in OPEN position | Measure the voltage to ground: There should be less than 0.2 V. |
|
| Vehicle ON mode, power sunshade switch released | Measure the voltage to ground: There should be battery voltage. |
|
||
| 14 | BRN | Vehicle ON mode, power sunshade switch in AUTO (OPEN) or AUTO (CLOSE) position | Measure the voltage to ground: There should be less than 0.2 V. |
|
| Vehicle ON mode, power sunshade switch released | Measure the voltage to ground: There should be battery voltage. |
