Subject: AB12 and Crash Sensors
Models Affected: Specific model years 2023-2024 Freightliner eCascadia
vehicles manufactured January 19, 2022, through May 30, 2023.

General Information
Daimler Truck North America LLC (DTNA), on behalf of its Freightliner Trucks Division, is initiating Field Service
Campaign SF682AB to modify the vehicles mentioned above.
Vehicles were built with numerous protections against crash-related damages or high voltage hazards. Early
production units were installed with a prior version of AB12 modules and with forward crash sensors not
engaged. These will be replaced by upgraded modules with crash sensors engaged. Additionally, optional
passenger protection airbag functionality will be enabled on certain vehicles.
There are approximately 366 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
Replacement parts are now available and can be obtained by ordering the kit and/or part number(s) listed below
from your facing Parts Distribution Center (PDC).
If our records show your dealership has ordered any vehicle(s) involved in campaign number SF682, a list of
the customers and vehicle identification numbers will be available on the DTNA Portal via OWL. Please refer to

Replacement of the Air Bag Sensor (AB12)
1.

Check the base label (Form WAR259) for a completion sticker for SF682 (Form WAR261), indicating this
work has been done. The base label is usually located on the passenger-side door, about 12 inches (30
cm) below the door latch. If a completion sticker is present, no work is needed. If a completion sticker is
not present, proceed to the next step.

2.

Park the vehicle on a level surface, place the vehicle in neutral, shut down the vehicle, and set the park
brake. Chock the tires.

3.

Disconnect the low-voltage batteries. For instructions, see Section 54.08 of the eCascadia Workshop
Manual.

4.

Open the driver-side door.

CAUTION
Do not remove the seat air spring without first using an appropriate method to secure the seat suspension in the extended position. If the seat suspension is not properly secured, the seat could lower unexpectedly, pinching a hand or finger between the suspension parts, resulting in personal injury.
5.

Drain all the air from the air tanks.

WARNING
Air lines under pressure can whip dangerously if disconnected. Drain all air from the air tanks before
disconnecting air lines. Disconnecting pressurized air lines can cause personal injury and/or property
damage.
