Verify the CTP is activated and enabled to communicate with the Daimler network.
19.1 Wait for 10 minutes to give the CTP ample time to establish a network connection.
19.2 Go to ‘Instrumentation’ tab, select ‘Chart,’ then select the ‘Real Time Data: Real Time Value’ checkbox. Verify ‘Activation OK’ is displayed under ‘Value,’ as shown in Fig. 35.
Is ‘Activation OK’ displayed under ‘Value’?
YES → The CTP01T software update is successful. Capture a screenshot that shows ‘Activation OK,’
and save the screenshot along with the repair order. Go to step 21.
NO → Attempt to establish the network connection again. Follow the substeps 19.3 and 19.4.
19.3 Disconnect the DiagnosticLink from the CTP, and wait for 5 minutes before reconnecting.

SF672 A and SF672 B - CTP Replacement
(When Software Updates/Flashing Attempts have Failed)
IMPORTANT: Only proceed with CTP replacement if authorized by Daimler Truck Technical Support at
1-855-253-0422.
CTP replacement is required only after USB Stick flashing attempts have failed and only when the SF672 work
instructions have indicated that CTP replacement is needed. The correct CTP replacement part(s) for SF672 A
and SF672 B are different and will depend on the part number of the failed CTP being replaced.
1.

Disconnect the connectors from the CTP ECU, located on the top shelf of the vehicle electronics bay.

2.

Press the CTP ECU firmly towards the back of the electronics bay to release the ECU from the forwardmounting slots, and lift the ECU.

3.

Remove the CTP ECU from the vehicle.

4.

After the CTP ECU is removed, mark an X on the CTP label to identify it as old and to eliminate any
chance of installing the ECU on another vehicle.

5.

Follow the substeps to determine the correct replacement CTP to be installed.
5.1

SF672 A (CTP1) → Using the part number of the removed (failed) CTP, see Table 3 for the new CTP
part number updating to CTP2, and for the antennas needed for the upgrade.

6.

SF672 B (CTP2) → Using the part number of the removed (failed) CTP, enter the part number in to
the Daimler parts look up/parts ordering system and determine the latest/newest part number in the
‘Supersession Chain.’ The correct replacement CTP is the latest/newest CTP2 part number. No antenna changes are needed for SF672 B.

Position the new CTP ECU in the electronics bay, and 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.

7.

Connect the CTP antennas to the matching color connector on the CTP.
7.1

SF672 A → Identify and replace the antenna(s) listed in Table 3. Route the cable for each of the antenna using Fig. 36 as a reference. Mounting locations for each antenna being replaced is identified
in Fig. 37. Before installation, clean the antenna mounting area using isopropyl alcohol. Make sure
the mounting surface is completely dry before using the included adhesive foam tape.
Figure 38, Fig. 39, and Fig. 40 identify each antenna type.
