|APPLICABILITY:||2013-14MY Legacy and Outback 2.5L Models|
|SUBJECT:||Reprogramming File Availability for Oil Level Detection|
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 specified below 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 (e.g an oil consumption test). The ECM must still be updated with this new logic and the oil level switch replaced.

SERVICE PROCEDURE / INFORMATION
Step 1– Reprogram the ECM using the applicable pack file from the table above.
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).

NOTE: The pack file listings provided in this bulletin are the latest available at the time of publishing. Updates are often released thereafter without revision to the bulletin. For this reason, it is critical to always have the latest version of Select Monitor III software installed on your system. You can confirm if a later version is available by entering the CID listed in this bulletin into FlashWrite. If a newer CID is shown as available in FlashWrite, reprogram using that file.
REMINDER: SOA strongly discourages the printing and/or local storage of service information as previously released information and electronic publications may be updated at any time. Always refer to STIS for the latest service information before performing any repairs.
Subaru reprogramming files using a generic (non-OEM) SAEJ2534 pass-thru vehicle programming device are available by contacting Service Technical Information Company toll free at 1-866-428-2278. The cost for the CD-ROM with all reprogramming files is $75.00 plus S/H and applicable state tax. Files will be updated four (4) times per year, in CD-ROM format, with all available reprogramming service information at the same above offered cost. Authorized Subaru Dealers are provided the same reprogramming information.
Before purchasing, the reprogramming details can be found in the following Reprogramming J-2534 Files chart. Click the link to view the PDF chart.
Subaru J2534 Reprogramming software meets the latest available J2534-1 specification. Our Reprogramming J2534 Files chart does not specify the Calibration Identification Number (CID); however, this information is included in our offered CD-Rom.
Note: The ECM or TCM being reprogrammed may already contain some or all of the reprogramming files listed in the Reprogramming J2534 Files chart shown by release date. It is possible to damage the vehicles ECM/TCM during the reprogramming event. Once the reprogramming process has started, it is recommended not to interrupt the process until the event is completed. If you experience any problems, please contact your scan tool maker for further instructions.
No. Subaru has no reprogramming capability for model years 1996-1998. Starting with our 1999 model year, please see our Reprogramming Pre-J2534 Files chart for affected model reprogramming information.
