# Service bulletin 11\-150\-14R

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

"NOTE: THE INFORMATION IN THIS BULLETIN WAS ORIGINALLY PART OF TSB 11\-149\-14 BUT HAS BEEN SEPARATED OUT INTO THIS PUBLICATION TO SIMPLIFY APPLICABILITY AND THE CORRESPONDING SERVICE PROCEDURE. THIS BULLETIN ANNOUNCES THE AVAILABILITY OF REPROGRAMMING FILES TO OPTIMIZE THE ECM LOGIC FOR ENGINE OIL LEVEL DETECTION IN THE EVENT OF FALSE OR PREMATURE LOW ENGINE OIL LEVEL WARNING LAMP ILLUMINATION. SHOULD A CUSTOMER PRESENT A CONCERN WITH A LOW ENGINE OIL WARNING LAMP ILLUMINATION AND THE DIAGNOSIS INDICATE THE OIL LEVEL IS FULL OR NEARLY FULL \(OIL LEVEL BETWEEN THE FULL AND ADD MARKS/HOLES ON THE DIPSTICK\) AND THE CUSTOMER HAS NOT ADDED ANY ENGINE OIL, THE ECM MUST BE UPDATED WITH THIS NEW LOGIC. NOTE: ON 5MT MODELS ONLY, THE OIL LEVEL SWITCH MUST ALSO BE REPLACED. IF THE CUSTOMER HAS ADDED OIL, DETERMINE HOW MUCH WAS ADDED. BASED UPON THE INFORMATION PROVIDED, ESTIMATE WHERE THE OIL LEVEL WAS WHEN THE LAMP ILLUMINATED IN ORDER TO DETERMINE IF ANY ADDITIONAL ACTION IS REQUIRED BEYOND WHAT IS DESCRIBED IN THIS BULLETIN \(E.G AN OIL CONSUMPTION TEST\). REMINDER: ALWAYS CONFIRM ANY LOW OIL LEVEL LAMP FALSE ILLUMINATION IS NOT A RESULT OF A POOR ELECTRICAL CONNECTION OR GROUNDING CONCERN. INSPECT THE CIRCUIT FOLLOWING THE DIAGNOSIS FOUND IN THE APPLICABLE SERVICE MANUAL TO ENSURE NO OTHER RELATED CONCERN EXISTS."
