Official summary
HYBRID MODELS ONLY. This bulletin announces the availability of reprogramming files to optimize the ECM and address DTCs P0A78 and P1C2A. When either of these DTCs is stored, the Hybrid/HEV functions are inoperative. The new logic will prevent damage to the drive motor by adding a fail-safe feature for improved current level control.
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.
