Ac Inverter Unit
NOTE:
- Before testing, make sure the No. A2-7 (30 A) fuse in the under-hood fuse/relay box is OK.
- Before testing, make sure the No. C23 (7.5 A) fuse in the under-dash fuse/relay box is OK.
1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the AC Inverter Unit - Removal and Installation 6P 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 are 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 |
|---|---|---|---|---|
| 6 | YEL | Under all conditions | Check for continuity between terminal No. 6 and power outlet 3P connector terminal No. 1: There should be continuity. |
An open or high resistance in the ground wire |
| 2 | WHT | Under all conditions | Check for continuity between terminal No. 2 and power outlet 3P connector terminal No. 3: There should be continuity. |
An open or high resistance in the ground 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 AC Inverter Unit - Removal and Installation .
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 4 | LT GRN | Vehicle ON mode | Measure the voltage to ground: There should be battery voltage. |
|
| 1 | GRN | Under all conditions | Measure the voltage to ground: There should be battery voltage. |
|
| 3 | BLK | Under all conditions | Measure the voltage to ground: There should be less than 0.2 V. |
