SERVICE PROCEDURE / INFORMATION
NOTES: Only the Intake-related DTCs are applicable to Legacy, Outback and Forester models.
- Using the SSMIII, determine which DTC is stored.
- Determine the location of the suspect component using the DTC List on page 3.
- Swap the Oil Control Solenoid Valves side-to-side (intake to intake or exhaust to exhaust, not between intake and exhaust on same side) following the procedure in the applicable Service Manual.
NOTE: The o-ring and nylon backer ring on the OCV must be replaced prior to reinstallation as they both are one-time use items.
- Clear the ECM memory.
- Perform the model-specific Drive Cycle or Inspection Mode procedure for the corresponding DTC as shown in the chart on the next page.
- Follow the applicable procedure below for locating either Inspection Mode or Drive Cycle instructions to coincide with the reference chart found on page 3.
- For BRZ: Using the Service Diagnostics tab on the STIS home page, enter your vehicle search parameters (example: 2013 > BRZ). Next, using the DTC tab, enter P0021 for INTAKE-related DTCs or P0024 for EXHAUST-related DTCs. Select the applicable link from your search result (example: P0021: Camshaft Position “A” – Timing Over-Advanced or System Performance (Bank 2)). Follow the diagnostic outline down to TEST DRIVE (for Drive Cycle) information.
- For All Other : Using the Service Diagnostics tab on the STIS home page, enter your vehicle search parameters (example: 2013 > Outback). Next, enter specific DTC into the search term box.
