    Have 2014 Camry hybrid that had the HV battery replaced under warranty by Toyota. Drove it for a couple months with no issues. Then it died on me and couldn’t get a “ready” light. Thought the 12v battery was bad because I charged it and was able to drive for a couple weeks until it happened again. Changed the 12v with a new battery and still can’t get a ready light. Every time I do it only lasts several miles or for the day. I should mention it is not the Toyota oem 12v

    you will need to do some testing. if you don't have a charger and volt meter, purchase them. charge up the battery and then test the it after the car has been off a few hours, then repeat every day and report the results here.

    So I found a fusable link just barely blown. So I thought maybe it was making contact off and on and was giving me the inconsistency I was experiencing. Replaced it, and still no ready light. 12v battery is good, all fuses are good. Next thing I’m gonna start testing is relays I guess. ALL warning lights are on and check hybrid system but no engine codes.

    Key fob is working, and nothing new installed other then then HV battery by the dealer. But the car drove with no issues at all for over a month after that. Then all the sudden the issues started

    That’s what I thought at first to, but I don’t show one with my meter. I found a fusable link just barely blown. So I thought maybe it was making contact off and on and was giving me the inconsistency I was experiencing. Replaced it, and still no ready light. 12v battery is good, all fuses are good. Next thing I’m gonna start testing is relays I guess. ALL warning lights are on and check hybrid system but no engine codes. Any advice on where to start now?
