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 B0401 and B0402 are recorded as freeze frame data when the ignition switch becomes OFF. Therefore, if the engine is attempted to be started with an immobilizer key that is not registered, the DTC will not appear in the Subaru Select Monitor immediately. Turn the ignition switch to OFF, and turn it back to ON to check the DTC. At this time (when turning the ignition switch to ON again), note that the DTC is displayed as freeze frame data even when using a registered immobilizer key.
