MODELS:
FEC7T, FECZT
VEHICLES INVOLVED:
Certain 2019-2020 model year FEC7T and FECZT trucks.
NOTE:
The information contained in this document is intended for use by trained, professional technicians with the knowledge, tools,
and equipment to properly and safely perform diagnoses and repairs. It informs service technicians about conditions that may
occur in some vehicles, or provides information that could assist in proper vehicle diagnosis, service, or repair, and does not
indicate that a defect is present in every vehicle referenced in this bulletin. DO NOT assume that a symptom or condition, or a
described cause of a symptom or condition, affects any particular vehicle or that a described repair applies to any particular
vehicle. There can be multiple causes resulting in the same symptoms or conditions, and trained professional service
technicians must use their diagnostic skills to make evaluations on a case-by-case basis.

MODIFICATION:
The engine ECU software must be updated.
CAMPAIGN CLAIM SUBMITTAL:
Reimbursement claims are filed through FALCON using the Field Fix claim type. Enter all requested information.
The system will automatically apply the labor allowance and recall part.

Labor Description
Update the engine ECU software

Part Number
N/A

REPAIR PROCEDURE:
1. Park the vehicle on a flat, level surface, turn off the engine, apply the parking brake and chock the
wheels.
CAUTION! Do not release the parking brake or remove the wheel chocks until all modification
work has been completed.
2. Perform the Campaign using the attached modification procedure.

IMPORTANT! The PSI software must be updated to version 2.3.1
PRIOR to reprogramming the engine ECU.
When PSI program version 2.2 is opened, it will ask if you want to update.
Choose yes and version 2.3.1 will download and update.
If version 2.3.1 is already installed, no update request will appear.

COMMON PROBLEMS THAT CAUSE
ECU PROGRAMMING TO FAIL
There are a few common problems that may occur during ECU programming:
•

Loose cable connections

•

Loss of battery power at the diagnostic interface

•

Loss of battery power at the laptop

•

Low vehicle battery voltage

•

Loss of internet connection

Throughout reprogramming, WiFi strength, battery voltage and connection between the diagnostic equipment and
the truck MUST remain constant. Any fluctuation in WiFi strength, battery voltage, or connection between the
truck and the diagnostic equipment, may result in programming failure.
Take all precautions necessary to ensure continued communication between the equipment and the truck
including:
1. Ensuring that the truck’s battery is fully charged
2. Ensuring that the diagnostic interface is fully charged
3. Keeping the laptop fully charged, or if possible, connected to AC voltage
4. Double-checking all diagnostic harness and cable connections are secure
5. Ensuring that the laptop has a strong WiFi connection while programming
Failure to confirm all of the above may cause the programming to fail to the point of damaging the ECU
beyond reprogramming. Should this occur, the ECU may need to be returned to the manufacturer for repair
or in some cases require replacement. In either case, the customer’s vehicle will be out of service for an
extended period, and the repair or replacement may not be covered by MFTA Warranty.

ENGINE ECU PROGRAMMING PROCEDURE
Connect the laptop to WiFi so PSI Powerlink can download the updated ECU software from the Cloud. Ensure that the laptop
does not lose the WiFi connection during the programming process.

Open PSI Powerlink

Confirm it is Version 2.3 or higher

Connect to vehicle

Select the green plug

Wait about 2 minutes
for the connection

Select Calibrations from the drop down

New calibration should be
listed here as 38300042-3
