Measurement 4

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.

    > 2X00IN GENERAL WARNING NOTES FOR WORKING ON THE HIGH-VOLTAGE SYSTEM 

Preliminary work for measurement 4 

(High-voltage line from high-voltage charger to electric passenger compartment heater)

  1. Release and disconnect high-voltage line (high-voltage charger - electric passenger compartment heater) at the electric passenger compartment heater.
  2. Connect high-voltage test adapter > VAS 6558/9-6 - High-voltage test adapter HVA 280  to the high-voltage line (high-voltage charger - electric passenger compartment heater). Leave the second connection open.

  3. Perform measurement 4.
    1. 3.1 Setpoint value > 550 MOhm 
  4. Evaluate measured result 
    1. 4.1 If the measured value is within  the tolerance range, continue with measurement 4.1 
    2. 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.

    Measurement 4.1

  6. Perform measurement 4.1.
    1. 6.1 Setpoint value > 550 MOhm 
  7. Evaluate measured result. 
    1. 7.1 If the measured value is within  the tolerance range, repeat measurement.

      Contact Technical Support.

    2. 7.2 If the measured value is outside  of the tolerance range, replace electric passenger compartment heater.

      After replacing the electric passenger compartment heater, repeat measurement 1.
