Official summary

Some vehicles (with MAZDA CONNECT) may exhibit a condition where DTC U0323(PCM) / U0423(ABS) /U3000(IC) CANNOT be deleted when the TPMS warning light flashes and/or the TCS/DSC indicator lights are illuminated. This can happen if the ignition is turned OFF within 20 seconds after the ignition is turned ON in one of the following two situations. 1. The ?ROOM? fuse (Engine compartment) is NOT installed when battery level is low. 2. The CMU (Connectivity Master Unit) is NOT connected.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
