What firmware version are you on?

Normally occurs when something is overloading the 5v or 8V.

Hi, asking here so as not to start a new thread for the same codes.
Can you provide any insight into causes for DTC P0641 with firmware 2.23.0?

Thanks,

When 5V is not 5V. Same as above, something is overloading the 5V. You can watch the 5V channel, usually over a trace view to see what is happening.
