DTC P0456 Reprogramming File Availability
NUMBER: 11-126-12
DATE: 12/19/12
| APPLICABILITY: | 2011MY Legacy and Outback (Later Production) 2012MY Legacy, Outback, Forester Turbo and Tribeca |
| SUBJECT: | DTC P0456 Reprogramming File Availability |
INTRODUCTION
If you receive a customer concern of a “Check Engine” light but no reported drivability concerns, there is a possibility DTC P0456 may be stored in the ECM memory. This Bulletin announces the availability of updated ECM reprogramming files to address DTC P0456, “Evaporative Emission Control System Leak Detected (Very Small Leak)”.
IMPORTANT NOTES:
- Always confirm if the customer may have attempted to tighten the fuel cap following the occurrence of the CEL or possibly refueled the vehicle following the occurrence of the CEL. If either situation has occurred, the source of the CEL may have been resolved by proper seating of the gas tank cap.
- Always follow the proper Service Manual diagnostic procedures for this code.
- Do not assume this reprogramming is automatically applicable to the vehicle you are working on. Only after confirming an actual leak does not exist, should this file be installed. Otherwise, mis-diagnosis could occur and the customer may experience a repeat occurrence of the CEL.
“2011 Later Production Only” vehicles can be identified by the “OLD CID NUMBERS” shown in the chart on the next page.

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/TCMduring 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.
(4b) Are all pre-2004MY Subaru vehicles compatible with J2534?
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.
Both pre-J2534 reprogramming and J2534 pass thru reprogramming files are included in the offered HDS kit software for aftermarket service provider application.
