Official summary
Some vehicles may have multiple warning lights on while driving with DTCs U0131:00 and/or U0151:00 stored. U0131:00 - (ABS) - Lost communication with PCM U0151:00 - (ABS) - Lost communication with restraints control module This concern may be caused when the image processed (in the active driving display) becomes too complicated and stops the CAN communication, resulting in a CAN communication error. To eliminate this concern, the active driving display control software has been modified.
Vehicles covered
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.
