Hi,

I recently bought a used Mazda 3 2016 iSport and the TPMS light starts blinking for a few seconds and stays on and ABS light is always on. I went to the dealer and they said I need to replace ABS module but gave the part number as BHP1-57-K30A which comes up as SDM module. I am confused if its the SDM or ABS module which needs to be replaced. Error codes retrieved are U0415 ad U0452. Thanks in advance.

Those codes are for ABS signal data invalid and restraint module data invalid, so its possible the the SDM is bad. Its also possible they gave you the wrong part number. You would need to confirm with the dealer what the problem is and what needs to be replaced.

Hi,

Thanks for the response, the dealer told me that the sensors for TPMS and ABS are working correctly but its the interaction with the module which is a problem due to module being broken/faulty.
