Reprogramming File Availability for Oil Level Detection – 2012 Subaru Impreza 2.0L

SEOCONTENT-START

Bulletin Number: 11-149-14; Revised: 12/10/14 Page 1 INTRODUCTION This bulletin announces the availability of reprogramming files and a revised oil level switch 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 and the oil level switch replaced. The new oil level switch part number supplied in this bulletin must be used. 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 additional action is required beyond what is described in this bulletin such as an oil consumption test. The ECM must still be updated with this new logic and the oil level switch replaced. The new oil level switch part number supplied in this bulletin must be used. COUNTERMEASURE IN PRODUCTION The new ECM logic was incorporated into production according to the table below: MODEL STARTING VIN PRODUCTION DATE CHANGE Impreza 2.0L E*026663 September 5, 2014 XV Crosstrek E*337542 September 5, 2014 PART INFORMATION PART NUMBER DESCRIPTION 11136AA140 Oil Level Switch NUMBER: 11-149-14R DATE: 11/06/14 REVISED: 12/10/14 APPLICABILITY: 2013-14MY Impreza 2.0L NA Models 2013-14MY XV Crosstrek, Including Hybrid Model (HEV) SUBJECT: Reprogramming File Availability for Oil Level Detection SERVICE BULLETIN Continued… ATTENTION: GENERAL MANAGER q PARTS MANAGER q CLAIMS PERSONNEL q SERVICE MANAGER q IMPORTANT – All Service Personnel Should Read and Initial in the boxes provided, right. ©2014 Subaru of America, Inc.

NOTES: SOA now highly recommends connecting the Midtronics GR8 Diagnostic Battery Charger to the vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is being reprogrammed. Once the GR8 is connected to the vehicle, as long as the battery is fully charged, it takes less than 3 minutes to boot-up the charger, select the Power Supply Mode, and have the battery voltage stabilized and ready for reprogramming. VERY IMPORTANT: This information is applicable to the Midtronics GR8 Diagnostic Battery Charger ONLY. It does not apply to any other brand / type of “generic” battery charger whatsoever. ONLY the GR8 and its Power Supply Mode feature has been tested and approved by Subaru of America, Inc. (SOA). • If the GR8 indicates the vehicle’s battery must be charged, charge the battery using the GR8 before proceeding to reprogram the vehicle while using the Power Supply Mode. • Control module failures as a result of battery discharge during reprogramming are not a matter for warranty. Should any DTCs reset after the reprogramming update is performed, diagnose per the procedure outlined in the applicable Service Manual. Step 2 – 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 insure no other related concern exists. Step 3 – Once the ECM reprogramming has been completed and the oil level switch wiring has been confirmed to be OK, proceed with replacing the oil level switch assembly shown in the illustration below following the procedure outlined in the applicable Service Manual. Torque the 2 retaining bolts to 6.4 Nm (56 inch-pounds).Torque the 2 retaining bolts to 6.4 Nm (56 inch-pounds). Step 4 – Confirm the engine oil level has been restored to the FULL mark on the dipstick before releasing the vehicle.
