Subject: Common Telematics Platform Cummins Engine
Models Affected: Specific model years 2022-2023 Freightliner
Cascadia; and Western Star 47X and 49X vehicles manufactured
September 4, 2021, through September 15, 2022.

General Information
Daimler Truck 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 SF685 to modify the vehicles
mentioned above.
Certain vehicles spec’d with a Common Telematics Platform (CTP2) were shipped without the CTP2 due to
shortages from the supplier.
The CTP2 module will be installed and activated.
There are approximately 1,418 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 number listed below from your
facing Parts Distribution Center (PDC).
If our records show your dealership has ordered any vehicle(s) involved in campaign number SF685, a list of
the customers and vehicle identification numbers will be available on the DTNA Portal via OWL. Please refer to
this list when ordering parts for this campaign.

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.

Work Instructions
Subject: Common Telematics Platform Cummins Engine
Models Affected: Specific model years 2022-2023 Freightliner
Cascadia; and Western Star 47X and 49X vehicles manufactured
September 4, 2021, through September 15, 2022.

CTP2 Installation
1.

Check the base label (Form WAR259) for a completion sticker for SF685 (Form WAR261) indicating this
work has been done. The base label is usually located on the passenger door about 12 inches (30 cm)
below the door latch. If a sticker is present, no work is needed. If there is no sticker, proceed with the next
step.

2.

Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.

3.

Remove the electronics bay cover and the passenger-side lower dash cover. For instructions, see Section
60.06 of the applicable workshop manual.

NOTICE
Make sure that the cab floor is clear of debris and tools. If the vehicle power distribution module
(VPDM) is lowered on to debris, especially metal objects, it could permanently damage the VPDM.
IMPORTANT: The VPDM is positioned on the mounting tabs to assist with retaining the VPDM in position while
mounting fasteners are removed. Care should be taken so the VPDM does not fall to the floor after all four
mounting fasteners have been removed.
4.

Remove the four VPDM mounting fasteners, then gently lower the VPDM on to the cab floor. For instructions, see Group 54 of the applicable workshop manual.

5.

Position the new CTP2 ECU in the top shelf of the electronics bay, then press the ECU firmly towards the
back of the shelf. See Fig. 1. Lower the front of the CTP2 onto the surface of the shelf, and adjust its position horizontally until the tabs on the CTP2 are fully seated in the mounting slots.

NOTE: Some vehicles may not have a harness to connect to the large blue CTP USB connector, shown in
Fig. 2. In such cases, the CTP USB connector remains empty.
6.

Connect the CTP2 electrical harness connector and antenna connectors to CTP2. See Fig. 1 for connector and antenna connection locations.

Install the VPDM. For instructions, see Group 54 of the applicable workshop manual.

8.

Install the passenger-side lower dash cover and the electronics bay cover. For instructions, see Section
60.06 of the applicable workshop manual. Continue to CTP initialization.

CTP Initialization
1.

Connect an RP1210B-compliant vehicle diagnostic adaptor to the diagnostic connector on the vehicle.

2.

Connect the other end of the RP1210B-compliant vehicle diagnostic adaptor to the laptop.

3.

Turn the ignition key to the ON position.

4.

Open DiagnosticLink®.

IMPORTANT: Make sure that DiagnosticLink is updated to the latest version (8.20 at the time of publication, or
newer) before programming the vehicle. To update DiagnosticLink, from the menu bar, select ‘Tools,’ then select
‘Update’ from the dropdown menu.
5.

Allow all the automatic connections to complete.

6.

In the ‘Connections’ window, right click and select ‘Close Connections.’ If any failed device connections
remain, shown with a red indicator, right click and select ‘Clear all Connection Errors.’

IMPORTANT: Some interior/protected locations such as repair shops and covered awnings may reduce cellular
network and GPS satellite coverage, which could prevent CTP initialization and may require the vehicle to be
moved out to an open area to improve the signal strength for CTP initialization.
7.

From the menu bar, select ‘File,’ then select ‘Connect.’ In the ‘Manual Connection’ window that appears,
select the following devices to manually connect to them:
• ICUC01T
• CGW04T
• CTP01T

IMPORTANT: Any other devices connected to DiagnosticLink (other than the three listed above) may cause the
initialization process to fail.
NOTE: ‘CTP01T,’ as displayed within DiagnosticLink, represents the CTP ECU device and not the type of CTP.
Both CTP1 and CTP2 will display as ‘CTP01T.’
8.

Wait until all the three devices are fully connected and the connection indicators turn green. See Fig. 3.

If prompted, enter your credentials to connect DiagnosticLink to the server.

13.

Wait until the initialization process is complete, and the last line in the initialization progress text field
reads, ‘Vin written to device and required data was sent to server.’

14.

Monitor the ‘CTP Activation Status from ECU,’ shown in the ‘CTP current status’ panel. Within 10 minutes
from the end of the initialization process, the ‘CTP Activation Status from ECU’ should change and display
‘Active OK.’
If ‘GSM OK’ displays instead of ‘Activation OK’ when the initialization process is completed, then the vehicle needs to be moved to an open air environment for better GPS satellite coverage, before running the
CTP initialization again.
Is ‘Active OK’ displayed under the status?
YES → Go to step 16.
NO → Disconnect DiagnosticLink from the vehicle. Turn the ignition key to the OFF position. Wait for five
minutes, and attempt to initialize the CTP again, repeat the steps 3 through 14.

15.

Check again if ‘Active OK’ is now displayed under the status.
YES → Go to the next step.
NO → Contact Daimler Truck Technical Support at 1-855-253-0422, option 4, from 5 A.M. to 4 P.M. Pacific
Time, Monday through Friday.

18.

Select the ‘Full Screen’ button again to return to the normal view.

19.

Verify the CTP is activated and enabled to communicate with the Daimler network.
19.1 Wait for up to 10 minutes to give the CTP ample time to establish a network connection.
19.2 Go to ‘Instrumentation,’ ‘Chart,’ then select the ‘Real Time Data: Real Time Value’ checkbox. Verify
‘Activation OK’ is displayed under ‘Value,’ as shown in Fig. 7.
Is ‘Activation OK’ displayed under ‘Value’?
YES → The CTP software update is successful. Capture a screenshot that shows ‘Activation OK,’
and save the screenshot along with the repair order. Go to step 20.
NO → Attempt to establish the network connection again. Follow the substeps 19.3 through 19.6.
19.3 Disconnect DiagnosticLink from the vehicle, and turn the ignition key to the OFF position.
19.4 Wait for at least five minutes, then turn the ignition key to the ON position.
19.5 Repeat steps 4 through 9 (on page 6) to connect to the three listed devices.
19.6 Wait up to an additional 10 minutes for the CTP to reattempt establishing the network connection. If
the CTP does not connect to the network even after 10 minutes, contact Daimler Truck Technical
Support at 1-855-253-0422, option 4, (5:00 A.M. to 4:00 P.M. Pacific time, Monday through Friday).
