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

2.

Make sure the ignition key and battery cut-off switch (if equipped) are in the ON position.

IMPORTANT: Do not turn the ignition or the battery cut-off switch OFF until the software installation is complete.
The vehicle batteries should maintain 12.4 volts or higher during the CTP software update. If needed, a battery
charger should be connected.
3.

Connect the Nexiq USBLink™ 2 box to the diagnostic connector on the vehicle.

4.

Connect the Nexiq USBLink 2 box to the laptop.

5.

Open DiagnosticLink®.

IMPORTANT: Make sure that DiagnosticLink is updated to the latest version (8.15 SP1 at the time of publication, or newer) before programming the vehicle. To verify, go to ‘Help,’ then select ‘About.’ See Fig. 8 and
Fig. 9.
To reduce the possibility of disruption during programming, make sure DiagnosticLink is connected to CTP01T
only.
6.
If other modules are already connected in the ‘Connections’ window, select ‘Close Connections’ to remove
all connected devices.

• If the green dot beside ‘Connected to CTP’ on the top, and the green dot beside ‘Ready to start’ at
the bottom do not appear, disconnect the CTP01T, close and restart DiagnosticLink program. Repeat
steps 5 through 10. If the issue still persists after a second attempt, call Detroit Connect support at
855-253-0420, or email [email protected].

IMPORTANT: The file name of the software copied in the USB drive must be ‘topas_sw_update.tar.gz’ in order
for DiagnosticLink to recognize the file for a successful CTP software update.
NOTE: The USB Adapter must be On-the-Go (OTG) protocol compliant. Non-OTG compliant adapters may result in failure of the CTP software update.
11.

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.
12.

Remove the four VPDM mounting fasteners, then gently lower the VPDM on to the cab floor. See Fig. 15.

13.

Locate the CTP on the upper shelf in the electronics bay. Using a USB mini to USB A adapter, connect the
USB drive containing the SF657 software to the CTP at the large blue USB mini connector. See Fig. 16.
Some vehicles may already have a harness connected at the large blue CTP connector, which must be
disconnected for this procedure. Make sure the USB adapter and the USB stick are completely inserted.

IMPORTANT: In order to minimize the possibility of disruptions during the CTP flashing procedure:
• The USB flash drive and the mini USB adapter must remain fully connected to the CTP.
• Vehicle power and ignition should remain ON.
• Vehicle batteries should maintain 12.4 volts or higher, or a battery charger should be connected.
• Laptop must not be unplugged from the vehicle.
• Laptop must not be allowed to go to sleep.
• Laptop must not be used for any purpose other than flashing the CTP.
14.

After the USB drive and adapter are connected to the CTP, select the ‘Start’ button in the ‘CTP USB Stick
Flashing’ window to begin the flashing process. Make a note of the time when the flashing process starts.

NOTE: The flashing process is automated and requires no interaction with the panel throughout the process.
The CTP will shut down and go offline before installing the update. The message ‘Waiting for CTP to Reset’ will
now appear and remain at the bottom of the ‘CTP USB Stick Flashing’ window while the CTP is offline for approximately 30 minutes until the new software is installed and activated. The message ‘Flashing Complete’ may
also appear at the bottom of the ‘CTP USB Stick Flashing’ window. See Fig. 17 and Fig. 18.
15.

Approximately 30 minutes after starting the CTP USB stick flashing process, or after the ‘Flashing Complete’ message is displayed, close the ‘CTP USB Stick Flashing’ window, then connect the DiagnosticLink
to CTP01T. See steps 6 through 8.
If the CTP01T does not connect, the software update may still be in progress and may not respond. Wait
for an additional 10 minutes between attempting to connect with CTP01T. If CTP01T still does not connect
to DiagnosticLink even after 50 minutes from the start time noted in step 14, call Detroit Connect support
at 855-253-0420, or email [email protected].

Once the CTP01T connection turns green in the ‘Connections’ window, go to ‘Actions,’ ‘Telematics’, then
select ‘CTP USB Stick Flashing.’ Verify the ‘fbsVersion’ is ‘169.413.907.’ See Fig. 19. If the ‘fbsVersion’
does not match the above version, disconnect the CTP01T and connect again. Then verify the version
again.

Verify the CTP is activated and enabled to communicate with the Daimler network.
17.1 Wait for 10 minutes to give the CTP ample time to establish a network connection.
17.2 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. 20.
Is ‘Activation OK’ displayed under ‘Value’?
YES → The CTP01T software update is successful. Go to step 18.
NO → Attempt to establish the network connection again. Follow the substeps 17.3 and 17.4.

Using the four mounting fasteners, install the VPDM.

19.

Install the passenger-side lower dash cover and the electronics bay cover. For instructions, see Group 60
of the applicable workshop manual.

20.

Clean a spot on the base label (Form WAR259), write the campaign number SF657 on a blank gray
completion sticker (Form WAR261), and attach it to the base label, indicating this work has been completed.
