CTP Replacement, 4G Antenna Installation, CTP Initialization
1.
Check the base label (Form WAR259) for a completion sticker for SF673 (Form WAR261), indicating this
work has been done. The base label is usually located on the passenger door 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 Group 60 of the applicable workshop manual.
NOTICE
Make sure that the cab floor is clear of debris and tools. If the 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. See Fig. 1.

5.
Locate the CTP on the top shelf of the electronics bay, and disconnect the electrical connectors from the
CTP ECU.
6.
Press the CTP ECU firmly towards the back of the electronics bay to release the ECU from the forwardmounting slots, and lift the ECU.
7.
Remove the CTP ECU from the vehicle.
8.
After removing the ECU, mark an ‘X’ on the CTP label to identify it as old, and to eliminate any chance of
installing the ECU on another vehicle.
9.
Determine the correct replacement CTP part(s) to be installed.
• SF673 A → Install the new CTP2 (25-SF673-001) and the new 4G antenna (66-11663-000).
• SF673 B → Install the new CTP2 (25-SF665-000). No antenna replacement needed.
10.
Position the new CTP ECU in the electronics bay and then press the ECU firmly towards the back of the
shelf. Lower the front of the ECU on to the surface of the shelf and adjust its position horizontally until the
tabs on the ECU are fully seated in the mounting slots.
11.
Connect the CTP antennas to the matching color connector on the CTP. See Fig. 2.
Only for vehicles in SF673 A:
11.1
Install the new 4G antenna. See Fig. 3.
11.2
Route the 4G antenna cable, as shown in Fig. 4.

17.
Connect the other end of the RP1210B-compliant vehicle diagnostic adaptor to the laptop.
18.
Open DiagnosticLink.
IMPORTANT: Make sure that DiagnosticLink is updated to the latest version (8.17 SP1 at the time of publication, or newer) before programming the vehicle.
19.
Allow all automatic connections to complete.
20.
Right-click in the ‘Connections’ window, and select ‘Close Connections.’ If any failed device connections
remain (shown with a red indicator), right-click and select ‘Clear All Connection Errors.’
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.’
21.
From the menu bar, select ‘File,’ then select ‘Connect.’ In the ‘Manual Connection’ window that appears,
select the following devices, one at a time, 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.
22.
Wait until all three controllers are fully connected and the connection indicators turn green. See Fig. 5.

NOTE: 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 signal strength for CTP initialization.
24.
Select the ‘Initialize CTP’ tab. Verify the vehicle identification number (VIN) from the new CTP2 displays
default ‘AAAAAAAAAAAAAAAA,’ or the VIN from the connected vehicle. See Fig. 6.
NOTE: If CTP does not display the VIN from the connected vehicle or default ‘AAAAAAAAAAAAAAAA,
then follow steps 3 thru 14 to replace the CTP2. After completing steps 3 thru 14, continue with step 15.
25.
Select ‘Initialize’ to run the initialization process.

If prompted, enter your credentials to connect DiagnosticLink to the server.
27.
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.’
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 display ‘Active OK.’
28.
If ‘GSM OK’ displays instead of ‘Active OK’ when the initialization process is complete, then the vehicle
needs to be moved to an open air environment for better GPS satellite coverage, before running the
CTP initialization again, starting with step 24.
Is ‘Active OK’ displayed under the status?
YES → Go to step 30.
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, repeating steps 15 through 28.
29.
Check again if ‘Active OK’ is now displayed under the status.
YES → Go to the next step.
NO → Call Daimler Truck Tech Support, 1-855-253-0422, option 4, 5 a.m. to 4 p.m., Pacific Time, M-F.
