|APPLICABILITY:||2014 XV Crosstrek Hybrid (HEV) Models|
|SUBJECT:||Reprogramming Files for DTC U0110|
This bulletin announces the availability of Drive Motor Control Module (DMCM) reprogramming to address DTC U0110 on 2014MY XV Crosstrek Hybrid models. U0110 may set when communication from the DMCM to other control modules included in the CAN system is lost. This loss of communication may occur in sub-freezing temperatures if the ignition is switched back to the “ON” position immediately after being switched “OFF”.
COUNTERMEASURE IN PRODUCTION
This new logic was incorporated into production April 22, 2014 starting with VIN E*294807.

SERVICE PROCEDURE / INFORMATION
IMPORTANT: When checking for stored DTCs, an “All Systems Check” will not show “past” DTCs in memory. Always perform an “Each System Check” to identify both “present” and “past” DTCs PRIOR to performing any reprogramming or clear memory function.
Step 1 – NOTE: U0110 is not limited to just the DMCM. For this reason, perform an “Each System Check” using the SSMIII to determine if U0110 or other DTCs such as: P0AC4, P0700, P0A7B, C1424, C1431, C1451 and / or C1452 are stored in any control module. These DTCs may be a result from U0110. If U0110 is stored with this list of other DTCs, always perform the reprogramming procedure first.
Step 2 – Once the reprogramming procedure is completed, clear the memory in each system.
Step 3 – Road test the vehicle to see if any DTCs reset before releasing the vehicle. If any DTCs reset, confirm the latest software version has been installed by verifying the current CID matches the number supplied in the table above.
Step 4 – O nce the latest CID has been verified, proceed with diagnosing any stored DTCs using the procedure in the applicable Service Manual.
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.

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.
