- ESD Work Surface -VAS6613-. Refer to → Electrical System General Information; Rep. Gr.97; ESD Work Surface VAS6613.
DANGER!
Damaged high voltage components may produce dangerously high voltage.
Note the following when working near high voltage components and cables:
- Do not use tools that have sharp edges, that are used for cutting or shaping, or that generate heat, such as welding, soldering, hot air or thermal adhesive equipment.
- Inspect the high voltage components in the area where the work will be performed before starting the procedure.
- Perform a visual inspection of the Electric Drive Power and Control Electronics -JX1-, the Electro-Drive Drive Motor -V141-, the Electrical A/C Compressor -V470- and the high voltage cables when working inside the engine compartment.
- Perform a visual inspection of the high voltage cables and the covers when working on the floor panel.
- Perform a visual inspection of the high voltage cables and the electro-box with the High Voltage System Maintenance Connector -TW- when working in the rear of the vehicle.
- Perform a visual inspection of all of the potential equalization cables.
- Note the following when performing the visual inspection:
- None of the components may display any exterior damage.
- The high voltage cable insulation and the potential equalization cables may not be damaged.
- The high voltage cables may not be deformed in any way.
- Each high voltage component muss be labeled with a red warning label.
