I finally got around this week to installing my OVMS v3.1 unit (Firmware 3.2.013) in my roadster (1.5) Everything is working fine - except activating OBD2 on can3 crashes the VMS. Numerous warnings pop up around lost signal for switchpack, VMS, BMB etc and door handles etc stop working. Running OBD2 ecu on can1 and can2 works fine. After looking through the developer doc, maybe one of the MCP2515 controllers is shot? As a work around, I am considering cutting open my obd2 cable to rewire the obd connector to can2 on the DIAG port -- other suggestions? Separately, Code: charge cooldown is not working, the error is Code: Error: Could not start cooldown . Any ideas what I am missing? Thank you!
