Service bulletin N192264170

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

N192264170 - SUB - Certain 2019 model year Cadillac XT4 vehicles equipped with a 2.0L. 4-Cylinder Turbo engine do not properly clear the permanent status for EBCM DTC U0100 (loss of communications with ECM) or U0101 (loss of communications with TCM) if a service tool was used to clear these DTCs. Vehicles with the permanent status set for these DTCs could potentially fail an emissions inspection in certain jurisdictions that check the permanent status of DTCs. Dealers will reprogram the electronic brake control module (EBCM).
