A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Start the engine and turn the tester on.
3. Warm up the engine.
4. Select the following menu items: Powertrain / Engine and ECT / Active Test / Control the VVT Linear (Bank 1) or Control the VVT Linear (Bank 2).
5. Check the engine speed while operating the oil control valve using the tester.

   OK

   Tester Operation	Specified Condition
   0%	Normal engine idle speed
   100%	Engine idles roughly or stalls (soon after OCV switched from OFF to ON)

NG → See step   4 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch on (IG) and turn the tester on.
3. Clear the DTCs, refer to DTC CHECK / CLEAR .
4. Start the engine and warm it up.
5. Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
6. Enter the following menus: Powertrain / Engine / Trouble Codes / Pending.
7. Read the DTCs using the tester.

2. Turn the crankshaft to align the timing marks of the crankshaft.
3. Align the notch of the crankshaft pulley to the "0" position.
4. Check if the timing marks of the camshaft pulley and camshaft bearing cap align.
5. Turn the crankshaft clockwise by 360° if the timing marks do not align. Check if they align once again.

   OK

   The timing marks of the camshaft pulley and the camshaft bearing cap align when the notch of the crankshaft pulley is in the "0" position.

NEXT: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch on (IG) and turn the tester on.
3. Clear the DTCs, refer to DTC CHECK / CLEAR .
4. Start the engine and warm it up.
5. Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
6. Enter the following menus: Powertrain / Engine / Trouble Codes / Pending.
7. Read the pending DTCs.

   OK

   No pending DTC output.

   HINT: 

   DTC P0011, P0012, P0021 or P0022 is output when foreign objects in engine oil are caught in some parts of the system. These codes will stay output even if the system returns to normal after a short time. These foreign objects are then captured by the oil filter, thus eliminating the source of the problem.
