Press the CTP ECU firmly towards the back of the electronics bay to release the ECU from the forward mounting slots, then lift the ECU.

3.5

Remove the CTP ECU from the vehicle.

3.6

After the removal of the ECU, mark an "X" on the CTP label to identify it as old.

3.7

Position the new CTP ECU in the electronics bay, 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.

NOTICE
DiagnosticLink 8.12sp2 or newer, is required to complete this procedure, as well as a reliable internet
connection. The procedure cannot be performed offline. The loss of internet connection may result in
failure of the CTP activation.
IMPORTANT: This procedure is not complete until the successful activation of the CTP has been confirmed
through DiagnosticLink 8.12sp2. The execution of all the steps, in the correct sequence, is critical to a successful CTP replacement and activation.
4.

Connect the vehicle to DiagnosticLink 8.12sp2, or later.

5.

Allow all automatic connections to complete.

6.

Right-click in the Connections window, and select Close Connections. If any failed controller connections
remain, shown with a red indicator, right-click and select "Clear All Connection Errors."

7.

In DiagnosticLink, click File > Connect and then, one at the time, select the following controllers to manually connect to them.
• ICUC01T
• CGW04T
• CTP01T

IMPORTANT: Any other controllers, other than the three listed above, connected to DiagnosticLink may cause
the initialization process to fail.
