Cause : Brak. resist. comes when braking resistor overload I x t. Brake resistors can be equipped with a thermal switch to detect a potential overload condition. When a resistor is overloaded, it attempts to dissipate more heat than it was designed to do.

1. Read the battery value in 11 00 .. 33 99
2. Increase the resistor ohmic value.
3. Check that 11 00 .. 33 00 and 11 00 .. 33 11 are set correctly.
4. Check the resistor wiring.
