Tesla diagnostic code in the EPAS (EPAS) module. Motor Driver Runtime Error: Calculation for new Pulse Width Modulation (PWM) commands has timed out. FOR has missed the time at which the PWM values for the next 500?s cycle must be calculated. The output of the PWM is cyclical, meaning one cycle is divided into several sections. After about 75% of the cycle time, the FOR needs the PWM values for the next cycle to be calculated. After the completion of processing the measured values started by the FOR, it must compute the new PWM values in approximately 20% of the cycle time. If the FOR takes longer than the beginning of the new cycle, the Error Handler reports an error and then recalculation begins.

This monitoring is active. The FOR and rotor speed must also be active for less than 500rpm, and the nominal current over an applicable value lie. If the conditions listed are satisfied and the actual current differs by more than 50% of the nominal current, the components' internal error filtering begins, which happens 100ms after reporting an error to the Error Handler. If it is within the error filter time (100ms) and the deviation is less than 50%, the components' internal back-filtering half-gradient of the error filtering is enabled.
