Steve Smith tackles an annoying fault on a BMW X5 40E PHEV with an intermittent HV insulation fault that was eventually pinned down to the HV A/C compressor thanks to a supporting DTC 801252 and the Pico Insulation tester.
The word “intermittent” always indicates some additional risk when committing to a repair based on the evidence obtained during diagnosis, and with HV systems, we appear to be heavily reliant upon serial data. Fortunately, there are additional tools at our disposal, and techniques to ensure minimal intrusions with the “suspect” system under load in its normal operating environment.
