Hello, I just purchased a 2007 Prius with the Hymotion L5 installed. I found the diagnostic PDF here, and it is throwing fault code 6 - the red light is blinking 6 times (the last one is a stead light before it starts blinking again). I see that is a battery sub-module temperature fault. Is this something I can troubleshoot myself and try to repair? Is it likely the battery packs in the L5 are still good after all this time, assuming it was installed at least 10 years ago?
