With Generic Scan Tool
CHECK ENGINE MALFUNCTION INDICATOR LAMP (MIL)
ACTIVATION OF CHECK ENGINE MALFUNCTION INDICATOR LAMP (MIL)
1) When ignition switch is turned to ON (engine off), the CHECK ENGINE malfunction indicator lamp (MIL) in the combination meter illuminates.
NOTE: If the MIL does not illuminate, perform diagnostics of the CHECK ENGINE light circuit or the combination meter circuit.
2) After starting the engine, the MIL goes out. If it does not, either the engine or the emission control system is malfunctioning.
3) If the diagnosis system senses a misfire which could damage the catalyzer, the MIL will blink at a cycle of 1 Hz.
4) When ignition switch is turned to ON (engine off) or to 'START' with the test mode connector connected, the MIL blinks at a cycle of 3 Hz.
OBD-II GENERAL SCAN TOOL
1. 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 the DIAGNOSTIC TROUBLE CODE (DTC) LIST.
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 following table.
NOTE: Refer to OBD-II general scan tool manufacturer's instruction manual to access generic OBD-II PIDs (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 following table.
NOTE: Refer to OBD-II general 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 the DIAGNOSTIC TROUBLE CODE (DTC) LIST.
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 diagram.
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 oxygen sensor output data and test ID (identification) are shown in the following table.
NOTE: Refer to OBD-II general scan tool manufacturer's instruction manual to access oxygen sensor monitoring test results (MODE $05).
OBD-II GENERAL SCAN TOOL
After performing diagnostics and clearing the memory, check for any remaining unresolved trouble data:
1) Connect test mode connector at the lower side of the instrument panel (on the driver's side), to the side of the center console box.
2) Open the cover and connect the OBD-II general scan tool to its data link connector in the lower portion of the instrument panel (on the driver's side), to the lower cover.
CAUTION: Do not connect the scan tools except for Subaru select monitor and OBD-II general scan tool.
3) Start the engine.
NOTE:
- Ensure the selector lever is placed in the "P" position before starting. (AT vehicles)
- Depress clutch pedal when starting the engine. (MT vehicles)
4) Using the selector lever or shift lever, turn the "P" position switch and the "N" position switch to ON.
5) Depress the brake pedal to turn the brake switch ON. (AT vehicles)
6) Keep engine speed in the 2,500 - 3,000 rpm range for 40 seconds.
NOTE: On models without tachometer, use the tachometer (Secondary pickup type).
7) Place the selector lever or shift lever in the "D" position (AT vehicles) or "1st" gear (MT vehicles) and drive the vehicle at 5 to 10 km/h (3 to 6 MPH).
NOTE:
- On AWD vehicles, release the parking brake.
- The speed difference between front and rear wheels may light the ABS warning light, but this indicates no malfunctions. When engine control diagnosis is finished, perform the ABS memory clearance procedure of self-diagnosis system.
8) Using the OBD-II general scan tool, check for diagnostic trouble code(s) and record the result(s).
NOTE:
- For detailed operation procedures, refer to the OBD-II General Scan Tool Instruction Manual.
- For details concerning diagnostic trouble codes, refer to the DIAGNOSTIC TROUBLE CODE (DTC) LIST.
