With Generic Scan Tool

HOW TO USE OBD-II GENERAL SCAN TOOL
1. Prepare a general scan tool (OBD-II general scan tool) required by SAE J1978.








2. Open the cover and connect the OBD-II general scan tool to the data link connector located in the lower portion of the instrument panel (on the driver's side), to the lower cover.
3. Using the OBD-II general scan tool, call up diagnostic trouble code(s) and freeze frame data. OBD-II general scan tool functions consist of:
1. MODE $01: Current powertrain diagnostic data
2. MODE $02: Powertrain freeze frame data
3. MODE $03: Emission-related powertrain diagnostic trouble codes
4. MODE $04: Clear/Reset emission-related diagnostic information
5. MODE $05: Oxygen sensor monitoring test results

Read out data according to repair procedures. (For detailed operation procedures, refer to the OBD-II General Scan Tool Operation Manual.)

NOTE: For details concerning diagnostic trouble codes, refer to Trouble Code Descriptions.

DATA LINK CONNECTOR (FOR OBD-II GENERAL SCAN TOOL AND SUBARU SELECT MONITOR)
1. This connector is used both for OBD-II general scan tools and the Subaru Select Monitor.





2. Terminal No.4 to No. 6 of the data link connector is used for the Subaru Select Monitor signal.

CAUTION: Do not connect any scan tools other than the OBD-II general scan tools and the Subaru Select Monitor, because the circuit for the Subaru Select Monitor may be damaged.

CURRENT POWERTRAIN DIAGNOSTIC DATA (MODE $01)
Refers to data denoting the current operating condition of analog input/output, digital input/output and/or the powertrain system.





A list of the support data and PID (Parameter Identification) codes are shown in the table.

NOTE: Refer to OBD-II general scan tool manufacturer's instruction manual to access generic OBD-II PID's (MODE $01).

POWERTRAIN FREEZE FRAME DATA (MODE $02)
Refers to data denoting the operating condition when trouble is sensed by the on-board diagnosis system.





A list of the support data and PID (Parameter Identification) codes are shown in the table.

NOTE: Refer to OBD-II genera scan tool manufacturer's instruction manual to access freeze frame data (MODE $02).

EMISSION-RELATED POWERTRAIN DIAGNOSTIC TROUBLE CODE (MODE $03)
Refers to data denoting emission-related powertrain diagnostic trouble codes.
For details concerning diagnostic trouble codes, refer to Trouble Code Descriptions.

NOTE: Refer to OBD-II general scan tool manufacturer's instruction manual to access emission-related powertrain diagnostic trouble codes (MODE $03).

CLEAR/RESET EMISSION-RELATED DIAGNOSTIC INFORMATION (MODE $04)
Refers to the mode used to clear or reset emission-related diagnostic information (OBD-II trouble diagnostic information).

NOTE: Refer to OBD-II general scan tool manufacturer's instruction manual to clear or reset emission-related diagnostic information (MODE $04).

OXYGEN SENSOR MONITORING TEST RESULTS (MODE $05)
Refers to the mode using oxygen sensor output data while the on-board diagnosis system is performing diagnosis on the oxygen sensor.





A list of the support data of oxygen sensor output and test ID (identification) are shown in the table.

NOTE:
- This system is not applicable to the front oxygen (A/F) sensor of the 2200 cc California spec. vehicles.
- Refer to OBD-II general scan tool manufacturer's instruction manual to access oxygen sensor monitoring test results (MODE $05).
