The vehicle does charge after two to four engage/disengage cycles with the handle at the charging port. I would have expected if there is a problem with the fuses that it would be a consistent failure to charge. Of course, that makes it more likely to be a charger failure, doesn't it?
fred_dot_u, confirm this with others, but many have had the same problem that you seem to have, charger cycles for several seconds and then fails to charge. In most cases it is just the fuses and not a faulty charger. Yes, the cost of a replacement charger is reasonable, $250-$350 is where we were, but it is $250 you may not need to spend. Of course taking out the charger, replacing the fuses, and putting back in, only to find out that it still does not work is incredibly frustrating.
I hope these thoughts help.
I want to draw your attention to the fact that at the beginning (for example, at the first attempt and at 2nd and at 3nd), on fred_dot_u
vehicle charging DOES NOT START.
However, charging does not start instantly and in the absence of a malfunction.
The process ALWAYS begins with a system health check. If some kind of malfunction is detected, then several more attempts are made to check and, if they also detect / confirm a malfunction, then the system is turned off.
After each of these attempts is unsuccessful, then after each time a fault code is recorded.
After the last failed attempt, the charger gets the Faulty status, and the contactors is disabled.
Depending on the cause / symptom of the malfunction, different codes may be recorded in the system. And the fuse fault code has a different cause than the "overcurrent" series codes...
And at the same time. If the Tesla software is inconsistent, the system determines the corresponding fault codes*.
And, if the problem is with charger hardware ID, then the RAV4EV charger can be reprogrammed*.
