DATE: 12/01/14
REVISED: 09/10/15

APPLICABILITY: 2012MY Impreza 2.0L NA Models
SUBJECT: Reprogramming File Availability for Oil Level Detection

 

INTRODUCTION

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).
