NOTE: Perform diagnosis of engine DTC when a DTC other than an immobilizer DTC is detected.

2. BODY INTEGRATED UNIT

NOTE:
- In immobilizer system, performing the starter relay control. When the body integrated unit detect the inconformity of reference code, immediately out put the starter relay cut signal to ECM, and then ECM stop the starter relay operation. In this case, engine does not start, and DTC is not recorded in ECM. Check that the engine does not start on the DTC of body integrated unit.
- DTC B1401 and B1402 are recorded as current malfunctions when the ignition is turned OFF. Because of this, if an engine is attempted to be started with an immobilizer key that is not registered, a DTC will not appear on the Subaru Select Monitor immediately. Turn the ignition switch to OFF once, then turn it back ON to check the DTC. At this time, (when turning the ignition switch back ON), note that even if a registered immobilizer key is used, the DTC will be displayed as a current malfunction.
