Measurement 2
WARNING: This page is about a different variant/trim than selected.
WARNING:
Incorrect handling of high-voltage components
- Electric shock
- Short circuit
- Fire
- Explosion
→ Only appropriately trained and authorized persons are permitted to work on high-voltage vehicles and components.
→ Required qualification: High voltage technician or high voltage expert.
→ Observe national requirements and legislation for this work.
→ Always use insulated tools, e.g. > VAS 6883 - Insulated Tool Set when working on these components.
→ Observe general warning notes for working on the high-voltage system.

Preliminary work for measurement 2
(High-voltage line from E-box to high-voltage charger)
- Release and disconnect high-voltage line (E-box - high-voltage charger) at the high-voltage charger.
E-box connection at high-voltage charger
- Connect high-voltage test adapter > VAS 6558/9-7 - High-voltage test adapter HVR 40
to high-voltage line (E-box - high-voltage charger). Leave the second connection open.
Measurement 2
- Perform measurement 2.
- 3.1 Setpoint value > 550 MOhm
- Evaluate measured result.
- 4.1 If the measured value is within the tolerance range, continue with measurement 3
- 4.2 If the measured value is outside
of the tolerance range, replace high-voltage line.
After replacing the high-voltage line, repeat measurement 1.
