Measurement 10

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.

Measurement 10

Measure resistance at pin 55 and pin 80 of the 12-volt connection for power electronics.

Refer to the wiring diagram for the pin assignment of the connectors 

Setpoint value < 0.5 Ohm 

Evaluate measured result 

If the measured value is within  the tolerance range, repeat measurements for pilot line fault finding. Contact Technical Support.

If the measured value is outside  of the tolerance range, visually inspect connectors and repair them if necessary. After carrying out repairs, repeat measurement 10.
