Information On Insulation Fault Finding: Notes

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2018 Porsche Cayenne, 2017 Porsche Cayenne, 2016 Porsche Cayenne, 2015 Porsche Cayenne, and 2014 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

The measurements must be performed using the insulation tester Insulation tester WE 1379 .
A measuring voltage of 500 V must be selected.
To obtain the required measuring resistance, the measuring voltage must be present on the insulation tester for at least 1 second .
The tolerance range is +/- 10% .
Two measurements must always be performed for each measuring point. Positive terminal on shielding and negative terminal on shielding.
A measurement is only regarded as being within the tolerance range if both measured values are within the tolerance range.
The direction of measurement of the insulation tester does not affect the test result.
The measured values must be documented in the "Insulation fault finding test log". The test log is stored under Standard forms in the PIWIS information system.
