Evaluate the test results .
1. 6.1. If the specified measured values from measurement 4.1 are not within the tolerance range and the specified measured values from measurement 4.2 are within the tolerance range:
  1. 6.1.1. Insulation fault in high-voltage line from high-voltage charger to rear PTC.
  2. 6.1.2. Replace high-voltage line from high-voltage charger to rear PTC following consultation with Technical Support. → 279319 REMOVING AND INSTALLING HIGH-VOLTAGE LINE FROM HIGH-VOLTAGE CHARGER TO ELECTRIC HEATER FOR HIGH-VOLTAGE BATTERY (REAR PTC)
2. 6.2. If the specified measured values from measurement 4.2 are not within the tolerance range and the specified measured values from measurement 4.1 are within the tolerance range:
  1. 6.2.1. Insulation fault in rear PTC.
  2. 6.2.2. Replace rear PTC following consultation with Technical Support. → Installing Electric High-Voltage Battery Heater
3. 6.3. The measured values from both measurements are not within the tolerance range.
  1. 6.3.1. Repeat the measurements.
  2. 6.3.2. Check measuring equipment and repeat the measurements.
  3. 6.3.3. Contact Technical Support.
4. 6.4. The measured values from both measurements are within the tolerance range.
  1. 6.4.1. Repeat the measurements.
  2. 6.4.2. Check measuring equipment and repeat the measurements.
  3. 6.4.3. Contact Technical Support.
