Please note that the following procedures may be performed on the CCP unit of the DCT
gearbox of the aforementioned models. Whenever a vehicle is brought to the workshop with
one of the DTC errors indicated on pages 21-23, the individual component of the CCP may
be replaced as described, and it will no longer be necessary to replace the complete CCP.
The following table lists the part numbers of the kits to be ordered for the aforementioned
procedures ONLY once the relative diagnosis has been approved by the FNA Help Desk
via an ROL (Red On Line).

Protocol for Managing DCT Gearbox Repairs
-

ROL approval is required prior to any pressure sensor replacement procedure.

-

The Dealer must complete the “DCT Gearbox Pre-Diagnosis Form” from TI 2622
and attach it to a new ROL with complete first level diagnosis..

- IMPORTANT Before proceeding with the repair procedures, you are required to complete the “DCT
Gearbox Pre-Diagnosis Form” from TI 2622 and attach it to a new ROL.

- IMPORTANT The S.T. Schedule for the models listed includes a specific table indicating the
corresponding operation codes for the procedures performed, which are necessary to
request reimbursement under warranty.

Replaced parts must be kept for at least 60 days, so that they may be returned if requested
or authorized for scrapping by SAT.
The following procedures need to be performed to remedy a fault identified on the
respective sensor (see error list on pages 21-23):
 Replacing “811” clutch pressure sensor C1 (Fig. 1)
 Replacing “812” clutch pressure sensor C2 (Fig. 1)
 Replacing “880” system pressure sensor (Fig. 2)

The following equipment and materials are necessary for this procedure:


Voltmeter (use the lowest measurement range possible for greater precision);



Stabilized power supply (with output voltage set to 5±0.1 V);



Wires for connecting to CCP sensor complete with probe as shown in Fig. 19.

- IMPORTANT The wires must be fitted with the terminals shown in Fig. 19 - 20 to prevent the risk of short
circuit.

Checking clutch pressure sensor C1 (811)
 Apply a voltage of 5±0.1 V to pin
10 (red), after connecting to pin
9 (red) (POWER) – Fig. 21.

Fig. 21

 Connect the negative wire of the
voltmeter to pin 8 (black)
(GND) – Fig. 21.
 Connect the positive wire of the
voltmeter to pin 22 (blue)
(SIGNAL), and read the value –
