OBDII scan tool (excluding hand-held tester):

  1. CHECK VALVE TIMING (CHECK FOR LOOSE AND A JUMPED TOOTH OF TIMING BELT) (See  REPLACEMENT  ) 

    NG: ADJUST VALVE TIMING (See  REPLACEMENT  ) 

    OK: GO TO NEXT STEP 

  2. CHECK OPERATION OF OCV 
    1. Start the engine.
    2. Check the engine speed with (1) and (2).
      1. Disconnect the V9 or V10 OCV connector.
      2. Apply the battery positive voltage between the terminals of the OCV.

      3. Reconnect the OCV connector.

    B: Go to step   4 

    A: GO TO NEXT STEP 

  3. CHECK IF DTC OUTPUT REOCCURS 
    1. Clear the DTCs.
      1. Disconnect the negative battery cable or remove the EFI and ETCS fuses for more than 60 seconds.
      NOTE: When disconnecting the battery cable, perform the "INITIALIZE" procedure (see ON-VEHICLE INSPECTION ).
    2. Start and warm up the engine.
    3. Drive the vehicle around for 10 minutes or more.
    4. Read output DTC using the OBD II scan tool.
    1. Standard: No DTC output. 

    HINT:

    *: DTC P0011, P0012, P0021 or P0022 is output when a foreign object in engine oil is caught in some part of the system. These codes will stay registered even if the system returns to normal after a short time. Foreign objects are filtered out by the oil filter.

    OK: VVT SYSTEM OK* 

    NG: GO TO NEXT STEP 

  4. INSPECT ECM (OCV SIGNAL) 
    1. Inspect using the oscilloscope.
    2. During idling, check the waveform between the specified terminals of the E8 ECM connectors.

    NG: REPLACE ECM (See  REPLACEMENT  ) 

    OK: GO TO NEXT STEP 

  5. CHECK OIL CONTROL VALVE FILTER 

    NG: REPLACE OIL CONTROL VALVE FILTER 

    OK: GO TO NEXT STEP 

  6. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSY (OCV) (See  INSPECTION  ) 

    OK: Go to step   8 

    NG: GO TO NEXT STEP 

  7. REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSY (OCV) 

    GO: GO TO NEXT STEP 

  8. CHECK CAMSHAFT TIMING GEAR ASSY (See  REPLACEMENT - RH BANK  or  REPLACEMENT - LH BANK  ) 

    OK: Go to step   10 

    NG: GO TO NEXT STEP 

  9. REPLACE CAMSHAFT TIMING GEAR ASSY 

    GO: GO TO NEXT STEP 

  10. CHECK FOR BLOCKAGE (OCV, OIL CHECK VALVE AND OIL HOLE) 

    NG: REPAIR OR REPLACE 

    OK: GO TO NEXT STEP 

  11. CHECK IF DTC OUTPUT REOCCURS 
    1. Clear the DTCs.
      1. Disconnect the negative battery cable or remove the EFI and ETCS fuses for more than 60 seconds.
      NOTE: When disconnecting the battery cable, perform the "INITIALIZE" procedure (see ON-VEHICLE INSPECTION ).
    2. Start and warm up the engine.
    3. Drive the vehicle around for 10 minutes or more.
