Subject: FCCC Viper Low Voltage Display
Models Affected: Specific model year 2019-2021 Freightliner Custom Chassis (FCCC) manufactured September 17, 2019, through
April 7, 2021.
General Information
Daimler Trucks North America LLC (DTNA), on behalf of its wholly owned subsidiary, Freightliner Custom
Chassis Corporation, is initiating Field Service Campaign SF637A to modify specific model year 2019-2021
Freightliner Custom Chassis manufactured September 17, 2019, through April 7, 2021.
In a low voltage condition, the instrument panel (IP) display may not come on when turning on ignition leaving
drivers without a functioning instrument panel. This would only occur at startup and the IP would function again
if the key is cycled with normal voltage.
Software will be updated to resolve the issue.
There are approximately 3,561 vehicles involved in this campaign.
Additional Repairs
Dealers must complete all outstanding Recall and Field Service campaigns prior to the sale or delivery of a
vehicle. A Dealer will be liable for any progressive damage that results from its failure to complete campaigns
before sale or delivery of a vehicle.
Owners may be liable for any progressive damage that results from failure to complete campaigns within a
reasonable time after receiving notification.
Please contact Warranty Campaigns for consideration of additional charges prior to performing the repair.
Work Instructions
Please refer to the attached work instructions. Prior to performing the campaign, check the vehicle for a
completion sticker (Form WAR261).
Replacement Parts
IMPORTANT: A USB flash drive with a storage capacity of 2 GB, or more, must be purchased by the dealership
for this procedure. No other files or folders other than the ones needed for this update should be in the flash
drive at the time of the update.
If our records show your dealership has ordered any vehicle(s) involved in campaign number SF637, a list of
the customers and vehicle identification numbers will be available on DTNAConnect.
Removed Parts

IMPORTANT: When the campaign has been completed, locate the base completion label in the appropriate location on the vehicle, and attach the gray completion sticker provided in the field service kit (Form WAR261). If
the vehicle does not have a base completion label, clean a spot on the appropriate location of the vehicle and
first attach the base completion label (Form WAR259). If a field service kit is not required or there is no completion sticker in the kit, write the campaign number on a blank sticker and attach it to the base completion label.

Software Installation
1.
Park the vehicle on a level surface, shut down the engine, and apply the parking brake. Chock the tires.
NOTICE
To ensure good battery voltage during programming, it is recommended to connect an appropriate battery charger to the vehicle batteries. Failure to do so could permanently damage the controller.
2.
Turn the ignition to the ON position.
IMPORTANT: A universal serial bus (USB) extension cable that connects the instrument panel electronic control
module (ECU) to the diagnostic connector may have been installed on the vehicle by the body builder. If a USB
extension cable was not installed, or missing, locate the instrument panel ECU, and plug the flash drive directly
into either of the USB ports on the instrument panel ECU. See Fig. 12.
The instrument panel ECU is usually located behind the dash. If unable to locate the ECU, contact the body
builder for support.
3.
Install the flash drive with the configuration files into the USB port next to the diagnostic connector under
the dash.

Press and hold the ‘OK’ button until a file, or a list of files appear, then release the ‘OK’ button.
• If a single file appears, press and hold the ‘OK’ button to begin the update. Release the ‘OK’ button
once the update begins.
• If a list of multiple files appear, highlight the first file, press and hold the ‘OK’ button to install the updates from that file. Release the ‘OK’ button once the update begins. After the updates from that file
are installed, repeat this process for the remaining files.
6.
When the software update is complete, the instrument panel will reboot. Once the reboot is complete, start
the vehicle and verify that the dash functions correctly.
IMPORTANT: If the software update process fails, or the module locks up, call the Medallion customer service
representative Cheryl Crane at 616-850-8015, or email at [email protected] for a replacement
ECU.
To minimize the downtime, Medallion will ship a re-manufactured ECU module already programmed with the
software update. A credit card, or purchase order (credit approval may be required) should be provided to Medallion by your dealership for a US $200 core charge. Your dealership will not be charged if the core is promptly
returned. In the event that the core is not returned, your dealership will be charged. A shipping label will be provided inside the box with the replacement ECU.
7.
Turn the ignition OFF, then remove the USB flash drive.
8.
Clean a spot on the base label (Form WAR259) and attach a campaign completion sticker for SF637
(Form WAR260) indicating this work has been completed.
