DBW Diagnostic Test
The DGC engine control module incorporates a diagnos-
tic test that may be used to verify proper drive-by-wire
throttle actuator operation. This diagnostic test is software
selectable through the EDIS using the ECIPP protocol.
This test permits full-authority operation of an electronic
throttle via the throttle command input while the engine is
in the “Stopped” state only. The ECM reverts to normal
operation if “Off” state is selected, ignition voltage is lost,
or engine speed is sensed.
To enable the test, go to the DBW page of the EDIS. Set
“DBW test mode” to “Enabled”. Double-click on the “TPS
Command” setting and enter the desired DBW throttle
actuator position. Under normal operation, the throttle
actuator should move to the position entered. To disable
the test, set “DBW test mode” to “Off.”
