OK... I have now seen my first Hymotion conversion enter the shop.... Bear with me folks cause I am something of a Purist! If it didn't come from Toyota it don't go on my Toyota. The car in question is owned by the local power company, (they recently bought fifty Prius from us) The driver stated he placed the car in Ready mode and suddenly "all the warning lights came on". When the car was towed to us, I got in and it went into Ready mode with no warning lights at all. I drove it a couple of miles and then attempted to connect the TechStream scan tool to check for codes. None of our three TechStreams would communicate with the car at all. They simply froze up during the uplink process. I spoke to someone from Hymotion who told me about the bypass connector located near the Hymotion battery, but even jumping it out did not help. We are now waiting for more technical data from Hymotion. Anybody hear of anything similar??
