High-voltage repairs on Hybrid and Electric vehicles
Before attempting any repairs that involve high-voltage components in Hybrid and Electric vehicles, a VTA ticket
must be opened with VW Technicians Helpline.
Technical Background
High Voltage topics are very diverse and latest information is changing regularly. Therefore, they need to be
addressed on a case-by-case basis. The VW Technicians Helpline can provide the latest information and
guidance to address the different concerns.
Production Solution

Service
If a repair involving high-voltage components or battery needs to be performed on a Hybrid or Electric vehicle, a
VTA ticket must be opened with VW Technicians Helpline to obtain direction with the latest information available.
If high voltage battery needs to be removed, replaced or disposed of for any reason, VW Technicians Helpline will
provide instructions for handling each case.
Hybrid batteries which are being replaced under Warranty for any reason and are stable can be shipped back for
analysis in the same container that the new battery was received in. VW QTM can assist in making the
determination if HV-Battery is stable for shipping or not.
For HV-Batteries that were damaged due to outside influence, VW Technicians Helpline can provide guidance in
having battery picked up from dealer for proper recycling.
Tip:
The electric components in the vehicle, such as the power electronics, the E-motor, the high voltage
battery and the electric A/C compressor, work in voltage ranges above 25V alternating current and 60V
direct current. Since the voltage exceeds the usual 12V electrical system voltage on a conventional
vehicle, the term “High Voltage” (HV) is used for these vehicles.
WARNING:
The vehicle’s high voltage electrical system and high voltage battery are dangerous and can cause burns,
other serious personal injuries, electrocution, and death. Never touch or let jewelry or other metal objects
contact high voltage cables or the high voltage battery and battery poles, especially if the cables, battery,
and battery poles have been damaged in any way.
Never do any work by yourself on the high voltage electrical system, the orange-colored high voltage wiring, or on
the high voltage battery. Never open, service, repair, or disconnect any part of the hybrid electrical system. Always
have work on the hybrid electrical system and systems that could be indirectly affected by it done by high-voltage
qualified, trained technicians who have the know-how, experience, documentation, and tools to do the work safely.
Never open or remove the orange-colored cover on the high voltage battery.
Never damage the orange-colored high voltage cables. Never remove them and never disconnect them from the
high voltage electrical system.
All work on the high voltage electrical system and the high voltage battery must be done in compliance with
Volkswagen standards and guidelines.
Personal protective equipment must be worn while the work is being performed.
Work must be performed in an open area, not in hallways or enclosed areas.

Warning Symbols
All high voltage components are identified with specific warning label stickers. The high voltage cables are
excluded from this.
There are two types of warning label stickers.
• a yellow warning sticker with the warning symbol for voltage
• a warning sticker with the word “DANGER” written in white letters against a red background.
The yellow stickers indicate high voltage components that are installed near the sticker or are hidden by a cover.
The “DANGER” sticker is located directly on the high voltage component.
