SF622A
REVISED NOTICE

Subject: Cascadia/49X ABS MBSP+ Controller
Software Update
Models Affected: Specific Model Year 2019-2022 Freightliner Cascadia, and Western Star 49X vehicles, manufactured
September 12, 2018, through March 10, 2021.

General Information
Daimler Trucks North America LLC (DTNA), on behalf of its Freightliner Trucks Division, and wholly owned
subsidiary Western Star Truck Sales, Inc., is initiating Field Service Campaign SF622A to modify the vehicles
mentioned above.
Certain vehicles have a WABCO Anti-Lock Braking System (ABS) controller that logs excessive 629-11 fault
codes which subsequently lead to additional downstream fault codes.
The ABS controller will receive a software update to eliminate erroneous fault codes and ensure its proper
function. After the software update, the truck will require a recalibration drive for the steering angle sensor.
There are approximately 95,677 vehicles involved.
REVISION: The work instructions have been revised.
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
This is a software update; no replacement parts required.
NOTE: In the event that WABCO determines a replacement ECU is needed, it will be provided at no cost.

Removed Parts
U.S. and Canadian Dealers, please follow Warranty Failed Parts Tracking shipping instructions for the
disposition of all removed parts. Export distributors, please destroy removed parts unless otherwise advised.
