Measurement 1

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.

  9. Measure resistance at connector at connection point (male), pin 4 and pin 11.

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

    1. 9.1 Setpoint value < 1.0 Ohm 
  10. Evaluate measured result 
    1. 10.1 If the measured value is within  the tolerance range, continue with measurement 2  .
    2. 10.2 If the measured value is outside  of the tolerance range, visually inspect all disconnected connectors. Repair them if necessary.

      After carrying out repairs, repeat measurement 1.
