General Information

On behalf of the DETROIT™ Powertrain Division listed below, Daimler Truck North America LLC (DTNA) has decided that
a defect that relates to emissions exists and is initiating a Field Service Campaign to modify affected vehicles.
= Detroit Diesel Corporation
= Freightliner Trucks Division
«= Wholly owned subsidiary/subsidiaries Freightliner Custom Chassis Corporation, Sterling Truck Corporation, Thomas
Built Buses, Western Star Truck Sales, Inc.

PROBLEM: OBD monitoring conditions for fault SPN 3711 FMI 11 may cause units to log a false fail. This may
result in the Malfunction Indicator Lamp (MIL) illuminating when no failure has occurred.
SOLUTION: Reprogramming of Aftertreatment Control Module (ACM) will correct this issue.

There are approximately 24,150 vehicles involved.

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 this field service campaign, check the vehicle for a gray
completion sticker (Form WAR261).

If the vehicle does not have a base label, clean a spot on the appropriate location, and attach a base label, prior to
attaching the completion sticker.

If a campaign kit is not required, write the campaign number on a blank sticker and attach it to the base label.
(Failure to install a completion sticker may result in a chargeback of the campaign claim.)

Claim Reimbursement - Labor Allowance

IMPORTANT: OWL must be viewed prior to performing the field service campaign to ensure the vehicle is involved and
the campaign has not been previously completed. Also, check for a completion sticker prior to beginning work.

You will be reimbursed for your parts, labor, and handling (landed cost for Export Distributors) by submitting your claim
through the Warranty system within 30 days of completing this campaign.

«In OWL, use the ‘Retrieve’ function and select the appropriate procedure. This will auto-populate the PFP

Check the base label (Form WAR259) for a gray completion sticker for D24M5 (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.

Park the vehicle on a level surface, place the vehicle in neutral, turn the keyswitch OFF, and set the parking
brake. Chock the tires.

Connect a 12-volt battery charger to the jump studs.
Turn the keyswitch ON (key ON, engine OFF).

Connect an RP1210B-compliant vehicle diagnostic adapter to the diagnostic connector on the vehicle. Connect
the other end of the adaptor to the laptop.

Open DiagnosticLink®

IMPORTANT: Make sure that DiagnosticLink® is updated to the latest version (8.20SP1 at the time of publication
or newer), before programming the vehicle.

when attempting to reprogram.

7. Make sure the VIN is correct in all modules (Aftertreatment Control Module (ACM), Common Powertrain
Controller (CPC), Motor Control Module (MCM), and if applicable the Transmission Control Module (TCM)) by
looking at the ‘Identification’ screen in DiagnosticLink. If the VIN is incorrect in any module, you can correct the
VIN under the ‘Actions’ dropdown menu in DiagnosticLink by selecting the ‘Check VIN Synchronization’ item.
Select ‘Start’ from this panel and follow the prompts. You will be prompted to cycle the key until the routine has
completed. When synchronization is complete, turn the keyswitch back ON and continue with the download
