Manufacturer summary

Original wording in English

The purpose of this Service Information bulletin is to advise Technicians about DTC B279A12: ?ENGINE IMMOBILIZER SYSTEM CIRCUIT SHORT TO AUX BATTERY?. For 2019MY, this DTC will always be indicated when inspecting for Readiness Codes using the Subaru Select Monitor. It will set because although the ECM?s self-diagnosis function includes the DTC, there is no target value included in the logic to test against. Therefore, the test result is incomplete and the DTC is stored. Even though the DTC is displayed, the system is normal and no attempt should be made to diagnose or repair it. The logic will be changed for 2020MY.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
