STEP 1. Check the high-voltage connector and wiring harness.
danger | Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle (Refer to GROUP 54Da - Precautions on how to use the high-voltage vehicle ). |
danger | Wear the specified protection equipment during the check. |
1. Shut down the high voltage (Refer to GROUP 00 - Precautions before Service - Precautions on handling high-voltage vehicle ). 2. Check the A/C compressor connector.
3. Check the high-voltage fuse No. 3 connecting bolt for looseness.
4. Visually check and check the continuity of the high-voltage fuse No. 3.
5. Visually check the following high-voltage wiring harnesses for damage.- High-voltage wiring harness on power drive unit (FEMCU) side
- High-voltage wiring harness on A/C compressor side
Is the check result normal?
Go to Step 4. : Tighten or replace the high-voltage fuse No. 3.
: Repair the connector(s) or the wiring harness wire(s) at the A/C compressor side. Then go to Step 4. : Repair the connector(s) or the wiring harness wire(s) at the power drive unit (FEMCU) side. Then go to Step 2.
