Don’t Rock the Super Duty

Some 2013 Ford F-350 Super Duty trucks equipped with a 6.7L diesel engine and built on or before 5/14/2013 may exhibit PTO (power take off) disengagement and/or loss of stationary idle control (SEIC) during operation. This may occur when the vehicle exhibits any movement, body roll or rocking.

For example: opening a door, standing on the bumper, turning the steering wheel or operating an aerial boom. When this occurs, the SEIC is disengaged and the engine rpm returns to base idle

1. Using an Integrated Diagnostic System (IDS) or equivalent, check for DTCs. If DTCs are present, this bulletin does not apply. Refer to powertrain control/emissions diagnosis.

If no DTCs are present, proceed to Step 2.

2. Reprogram the PCM to the latest calibration using IDS release 84.03 or higher. Calibration files may be obtained at www.motorcraft.com.
