Toyota GT86(FRS) ABS ECU error code C1241

Question

Hi i got a check engine light. Used Ecutek to check the engine code and got

error code C1241 from the ABS ECU, what does that mean. I have seen that code listed as a low battery problem from some toyota forums but why did it come from the ABS Ecu. Brake pads where changed the same day BTW

Can the dealership read and Clear error codes with my ecutek tune on board or should i just flash back to the stock ROM
