Summary
Service Bulletin - Due to PGM-FI software errors, vehicles that experience an evaporative leak check module (ELCM) circuit failure may not be able to turn off the MIL and clear DTC P2402, even if repaired. Some 2021 TLX Type S models have an additional software error in the FI-ECU related to the OBD system. Both of these do not comply with OBD regulatory requirements and may prevent the vehicle from passing a smog check.
