Power Tailgate Control Unit Input Test (2016)
NOTE:
- Before testing, make sure the No. C16 (10 A) fuse in the under-hood fuse/relay box are OK.
- Before testing, make sure the No. D10 (7.5 A) fuse in the driver's under-dash fuse/relay box is OK.
- Before testing, make sure the No. F1 (7.5 A), No. F13 (7.5 A) and No. F18 (40 A) fuses in the rear fuse/relay box is OK.
- Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.
1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the power tailgate control unit connectors
.NOTE: All connector views are shown from the wire side of the female terminals.
3. Inspect the connectors 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.
4. Reconnect the connectors, 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 tailgate control unit .
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired results not obtained |
|---|---|---|---|---|
| A1 | BRN | Under all conditions | Measure the voltage to ground: There should be battery voltage. |
|
| B19 | PNK | Under all conditions | Measure the voltage to ground: There should be battery voltage. |
|
| B20 | GRN | Under all conditions | Measure the voltage to ground: There should be battery voltage. |
|
| C8 | LT GRN | Power mode ON | Measure the voltage to ground: There should be battery voltage. |
|
| A2 | BLK | In all power modes | Measure the voltage to ground: There should be less than 0.2 V. |
|
| A4 | BLK | In all power modes | Measure the voltage to ground: There should be less than 0.2 V. |
|
| B3 | BLU | Shift position/mode in P | Check for continuity to ground: There should be continuity. |
|
| Shift position/mode in any position other than P | Check for continuity to ground: There should be no continuity. |
