DTCs can be retrieved by using either a Subaru Select Monitor or OBD-II scan tool. If using Subaru Select Monitor, follow manufacturer's instructions to retrieve DTCs.
- Raise and support vehicle. Ensure vehicle is secure and drive wheels are free. Open cover to Data Link Connector (DLC), located at lower left side of instrument panel, and connect scan tool. See Fig 1 .
- Ensure gear selector is in "P" position. Start engine. Move gear selector to "N" position, and depress brake pedal. Bring engine speed up to 2500-3000 RPM, and maintain for 40 seconds.
- Place gear selector in "D" position, drive vehicle between 3-6 MPH and maintain for 40 seconds. Retrieve and record DTCs. Perform appropriate test. See DIAGNOSTIC TROUBLE CODE INDEX table. If no DTCs are retrieved, repair by system. See DIAGNOSIS USING SUBARU SELECT MONITOR under SYSTEM TESTS.
