Intialization

INITIALIZATION

When repair work is performed on the ETS, "INITIALIZATION" of the system is sometimes required.

INITIALIZATION is the process by which the ETS Control Module "learns" and memorizes the DC Motor's Rotor position relative to the throttle plate position. It involves taking hundreds of data points of the electric motor's rotor position relative to the throttle plate position from fully closed to fully open and back to fully closed. This learning is critical for the electric motor's quick and precise control of the throttle valve.


PERFORMING THE INITIALIZATION

1. Turn the ignition key to the ON position (for less than one second) and quickly turn the ignition key back to the OFF position.

2. For the next 20 seconds, the ETS Control Module/PCM performs the INITIALIZATION process.

CAUTION: DO NOT turn the key back on until the INITIALIZATION is complete (20 seconds).
