Official summary
Service Update. The Engine Control Module (ECM) in certain vehicles may not properly clear the DTC U1962 (Unable to Authenticate Serial Data Message). If a communications fault were to occur, the DTC will remain set with the Malfunction Indicator Light (Check Engine Light) illuminated even if the condition resolves. Clearing the DTC with a service tool will not clear the permanent status of the DTC which could result in an emissions Inspection/Maintenance (I/M) test failure. Dealers are to reprogram the ECM.
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.
