Official summary
Some vehicles may exhibit the CHECK ENGINE light turning ON with DTC P0AB9:00 (PCM Start Signal System) stored in memory. This may be caused by a PCM Start Signal System error detected due to improper PCM logic. To eliminate this concern, the control software of the PCM has been modified.

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.
