Measurement 3
WARNING:
Incorrect handling of high-voltage components
- Electric shock
- Short circuit
- Fire
- Explosion
→ Only appropriately trained and authorised 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.
> 2X00IN GENERAL WARNING NOTES FOR WORKING ON THE HIGH-VOLTAGE SYSTEM
Preliminary work for measurement 3
(Check: High-voltage distributor, high-voltage charger, passenger compartment heater, electric drive motor, front power electronics)
- Release and disconnect high-voltage line (from high-voltage distributor to voltage converter) at the high-voltage distributor.
High-voltage line from high-voltage distributor to voltage converter
- Connect high-voltage test adapter > VAS 6558/9-6A - High-voltage test adapter
between high-voltage line (from high-voltage distributor to passenger compartment heater) and high-voltage distributor.
Measurement 3
- Perform measurement 3.
- 3.1 Setpoint value ≥ 1.1 MOhm
- Evaluate measured result
- 4.1 If the measured value is within the setpoint value range, continue with measurement 9 .
- 4.2 If the measured value is outside of the setpoint value range, continue with measurement 4 .
