Sevcon Throttle Error Gen 4

[amblerev]

Hello all, I have an EV conversion using a Sevcon G4 controller. It ran for several months, then it died on road with error code Throttle value (0x2620,0) is greater than 20% at power up. I am using a 12V hall type throttle with 0-5V analog output, and when I look at the throttle output in DVT is looks normal. The error happens as soon as the output hits .5V then resets when throttle is released. What I have tried so far:

1. reran all wiring - no change
2. Tried a different throttle with 5V powering and 0-5V output - no change
3. Hooked up the digital input to the Sevcon from the throttle on switch and configured it in the controller (and confirmed it is being correctly read)- no change
4. Reset the throttle limits multiple times in the DVT wizard - no change
5. Manually set the low limit in DVT on the throttle to .5V, that triggered a different throttle error for analog input wire off

I really do not think it is the throttle, in that the values shown in DVT looks like a normal 0-5V sweep. If anyone out there has experienced this, would appreciate the help.

After troubleshooting for two weeks with no luck, I did a complete reboot (disconnect HV and 12V, reboot laptop) and it went away.....I had tried disconnecting the HV and rebooting, but never together. Since then, I have been able to use this to clear any range errors that make no sense, which seems to happen a bit
