The condenser voltage went to 338 but the pack was at 350, so that is what triggered the condenser timeout flag, and that would set the HV error light on the dash.
But how can the condenser get any voltage at all if the main(+) never came ON? Maybe the contactor did come on, but the indicator switch is defective?
yes, it is confuses me too. I thought may be in the beginning car uses main(-) and charge contactor to charge condenser and if charge process finished well - car is switching on main(+). Is it possible?

1. Lately we seem to be hearing about several folks with dc/dc converter box/ charger box, having failures and issues. If the charger-dc/dc converter box was drawing too much current due to an internal fault, then it could cause the condenser chargeup time to be too slow. They share the same wire from the pack to the MCU, then there is a connector between the MCU and Charger. Try disconnecting that on the fat orange cable that connects the charger to the MCU and see if the condenser timeout error goes away when there is no load from the dcdc/charger box.
Yes, I could try it. But If car started I should see problems with 12v line or I should see that car is taking too much power in ready mode and not moving. But it was the same 0.4kW like before.

in this case it should stop immediately and not wait if condenser will reach battery voltage or not.
