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.
1. 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.
2. For All Other Models: 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. Select the applicable link from your search result (examples: ENGINE
