Electronic Throttle Control
Initialization
Electronic Throttle Control (ETC) provides refined throttle operation. Idle speed control throttle valve opening control TCS control and cruise control
functions are all performed by a single throttle valve. Under the following conditions the ETC throttle body will need to be initialized:
^
When the Throttle Position Sensor or the Accelerator Position Sensor signals are lost (circuit malfunction or connector(s) unplugged when circuit is
energized.)
^
When the Throttle Assembly is replaced
^
When the PCM is replaced.
Initializing the ETC throttle body accomplishes the following:
^
Completes system recognition of closed and wide open readings of the Throttle Pressure Sensors
^
Confirms proper circuit operation
^
Verifies throttle position feedback Below is the ETC System Initialization procedure:
1) Make sure the ignition is OFF for more than 10 seconds.
2) Turn the ignition ON for about one second (do not crank) then OFF again.
3) Leave the ignition OFF for more than 10 seconds.
4) Turn the ignition ON again for more than one second. This completes the initialize operation Note: Visually check the movement of the throttle valve
during initialize process.
To verify proper initialization check throttle valve motion from the accelerator operation by turning the ignition ON and cranking the engine. This
initialization procedure should only be performed once and only in the event of the conditions listed above.
