Manufacturer summary

Original wording in English

TSB: Some 2015 ? 2017 model year NX 200t and 2016 ? 2017 model year GS 200t, IS 200t, and RC 200t vehicles equipped with an 8AR-FTS engine may exhibit a MIL ?ON? condition with Diagnostic Trouble Code (DTC) P137800 (Pre-ignition Detected) followed by a ?Reduced Engine Power Visit Your Dealer? message on the Multi-Informational Display (MID) unit. The Engine Control Module/ECM (SAE Term: Powertrain Control Module/PCM) logic has been modified to reduce the possibility of this condition occurring.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
