I have a laptop loaded with ISTA software and cable. It has helped me troubleshoot wiring damage, but I am no expert. Do you have any instructions on how to use it to test HV batterie state of health?lopezjm2001 wrote: ↑Mon May 03, 2021 4:56 pmJust wandering if anyone has done their own HV battery health test using the BMW diagnostic software ISTA+. It involves fully charging the HV battery and then fully discharging the battery using the air-conditioning with the windows open. You can get this software on the net for a reasonable price from https://www.bcables.com/. Just need a OBD2 to ethernet cable.
