Title
Variable Geometry Turbo (VGT) Calibration: Premium Tech Tool (PTT) Displays
"Motor Disabled" Message, Operation Will Not Run, Will Not Complete When Running
Operation; Poor Performance Following Calibration - US10 And Newer Emissions,
Common Model Years 2014 And Newer
Cause
If the Variable Geometry Turbo Calibration ( VGT ) operation is unsuccessful, the VGT
may not respond normally and be stuck in a default position. This can cause poor
performance with no fault codes. This can be solved by ensuring the calibration finishes
correctly.
Solution
I. Run PTT Operation 2551-07-03-01 Variable Geometry Turbo, located
under the Calibrate tab.
II. Press the Play button for Step 1, Position. This step clears the end stops
and pre-positions the output gear for installation.
A. A Green Circle with Check Mark and Install Position message must be displayed as
shown below before proceeding further. If the correct status is observed, proceed to Step 3 of
the PTT operation.
B. If an error message and/or a Red Circle with an X is displayed as shown below, Operation
Step 1 did not complete correctly.
If this condition is observed:
1. Stop the calibration.
2. Exit the operation.
3. Restart the calibration operation.
4. Perform Operation Step 1 again until the conditions in Part A are observed.
III. Press the Play button for Step 3, Calibrate.
A. Allow the operation to run.
B. When the calibration completes, a Green Circle with Check Mark and Normal message
should display after calibration completes. There may be a delay between the test completion
and the message display.
C. If the operation fails and a Red Circle with an X is displayed with a "Motor Disabled"
message, proceed to Section IV below.
IV. If a "Motor Disabled" message is observed (most common when the
actuator is unbolted from the turbocharger) at any time during the
Operation:
A. Ensure the ignition key is turned ON.
B. By hand, spin the actuator output gear at least one full revolution as shown
below. This allows the motor to find the internal reference magnet on the output shaft.
C. Rerun Step 1 of the operation.
Note: It may be necessary to perform the steps above more than once to achieve a
successful result.
