Error code dealer or no dealer - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

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. But if i do flash back to stock the error code will go right?

I'm no expert, but unless your ECUTek tune changed something in the ABS system, the code should still be there when you flash it back to stock.

Also, IIRC its very VERY risky to flash a new tune when your battery is low.

That said, a quick google search says that C1241 is a low battery code, like you said. Try a new battery before going to the dealer.

I would reset the code and drive around for a bit to make sure the battery is fully charged. If it comes back, flash back to stock and bring it to the dealer.
