Work Procedure

DESCRIPTION 

Electric intake valve timing control (IVT) module requires the learning of camshaft reference position. This learning must be performed where the following operations are performed:

• Replacement of electric IVT control module
• Replacement of intake/exhaust camshaft position sensor
• Replacement of crankshaft position sensor
• Removal and installation of timing chain
• Replacement of the mechanical parts listed below:
  • Replacement of timing chain
  • Replacement of intake/exhaust camshaft
  • Replacement of intake/exhaust camshaft sprocket
  • Replacement of piston
  • Replacement of connecting rod
  • Replacement of crankshaft

NOTE: If learning is not performed after the replacement of the above listed parts, the engine may not be able to be started.

1. START 

   Do you have CONSULT ?

   YES>>

   GO TO 2.

   NO>>

   GO TO 3.

2. ELECTRIC INTAKE VALVE TIMING (IVT) CONTROL ACTUATOR REFERENCE POSITION LEARNING 
   1. With CONSULT:
      1. Turn ignition switch ON.
      2. On CONSULT screen, select All DTC Reading and check that any DTC is not detected.
      3. Select "Electric intake valve timing control learning" in "WORK SUPPORT" of "ENGINE".
      4. Touch "Start" and start the engine within 10 seconds.
      5. Let the engine be idle.
      6. Check that "COMPLETED" is displayed.

   Is the learning completed normally?

   YES>>

   END

   NO>>

   Check that DTC is not detected and restart the learning.

3. PERFORM ELECTRIC IVT CONTROL ACTUATOR REFERENCE POSITION LEARNING 
   1. Without CONSULT
      1. Turn ignition switch OFF.
      2. Disconnect electric IVT control actuator harness connector (actuator side).
      3. Turn ignition switch ON and wait at least 30 seconds.
      4. Turn ignition switch OFF.
      5. Reconnect the disconnected harness connector.
