Variable Valve Timing: Testing and Inspection
EXHAUST VALVE TIMING CONTROL LEARNINGEXHAUST VALVE TIMING CONTROL LEARNING: Description
Exhaust Valve Timing Control Learning is a function of ECM to learn the characteristic of exhaust valve timing control magnet retarder by comparing the target angle of exhaust camshaft with the actual retarded angle of exhaust camshaft. It must be performed each time exhaust valve timing control magnet retarder is disconnected or replaced, or ECM is replaced.
