Official summary
This Preliminary information communicates an issue where the aux switch "on" LED indicators do not illuminate within the aux switch if more than one aux switch is turned on. The aux switches do work regardless of how many are turned on, but the "on" LED indicator will only be illuminated in which ever aux switch is first pressed. Dealers are to reprogram the BCM to correct this concern.
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.
