Subaru Legacy BN/BS (2015-2019) Service Manual: General scan tool operation

1. HOW TO USE GENERAL SCAN TOOL

1. Prepare a scan tool (general scan tool) required by SAE J1978.

2. Connect the general scan tool to data link connector located in the lower portion of the instrument panel (on the driver’s side).

3. Using the general scan tool, call up each data. 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 DTC

(4) MODE $04: Clear/Reset emission-related diagnostic information

(5) MODE $06: Request on-board monitoring test results for intermittently monitored systems

(6) MODE $07: Initial emission-related powertrain DTC

(7) MODE $08: Request control for on-board system, test, and component

(8) MODE $09: Request vehicle information

4. Read out the data according to repair procedures. (For detailed operation procedures, refer to the general scan tool operation manual.)

NOTE:

For details concerning DTC, refer to “List of Diagnostic Trouble Code (DTC)”. List of Diagnostic Trouble Code (DTC)

2. MODE $01: (CURRENT POWERTRAIN DIAGNOSTIC DATA)

Refer to data denoting the current operating condition of analog input/output, digital input/output or the powertrain system.

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