Official summary
Some vehicles may experience a SBS/SCBS, LAS/LDWS and/or ADAPTIVE LED headlight /HBC warning light on with the DTC U0155:00 stored in memory. The warning lights may stay on while these functions are deactivated. This concern may be caused by faulty Instrument Cluster software. To eliminate this concern, the software has been modified. NOTE: The Mazda Diagnostic Reprogramming Tool (MDRT) loaner program begins effective Jan. 30, 2019.
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.
