                                              ON-BOARD DIAGNOSIS SYSTEM
 FUEL INJECTION (FUEL SYSTEM)


 6. On-board Diagnosis System
 A: GENERAL
    The on-board diagnosis system detects and indicates a fault by generating a code corresponding
 to each fault location. The engine malfunction indicator light on the combination meter indicates oc-
 currence of a fault or abnormality.
   When the engine malfunction indicator light comes on as a result of detection of a fault by the
 ECM, the corresponding diagnostic trouble code (DTC) and freeze frame engine condition are
 stored in the ECM.
  On the OBD-II conformable car, it is necessary to connect the SUBARU Select Monitor (SSM) or
 General Scan Tool (GST) to the data link connector in order to check the DTC.
   The SSM and GST can erase DTCs. This can also read freeze frame data in addition to other
 pieces of engine data.
   If there is a failure involving sensors which may affect drive control of the vehicle, the fail-safe
 function ensures minimum level of driveability.
 B: FAIL-SAFE FUNCTION
 For a sensor or switch which has been judged faulty in the on-board diagnosis, the ECM, if appro-
 priate, generates an associated pseudo signal to keep the vehicle operational. (The control be-
 comes degraded.)
