D6.11 REPLACING THE THE ELECTRONIC CONTROL
UNIT (TCU)
The transmission electronic control unit (TCU) is located inside the passenger
compartment, under the ECU covering shield, behind the passenger's seat.
To replace the ECU, follow the procedure described below:
1 - With the ignition key turned to running position, connect the SD-2 tester to the old
TCU and write down the mm value of the new clutch position ( D 6.12).
2 - Turn the key to the Stop position and detach the battery by operating on the
battery master switch
( L 2.02).
3 - REPLACE the old TCU with the new one (see "TCU removal").
4 - Reconnect the battery and turn the key to the ON position. By means of the SD-2
tester, execute the CYCLE procedure.
When the question new friction is displayed, answer NO, correct the default value
with the value noted, as described in point 1. The maximum variation accepted by the
system is 2 mm. If this should not be sufficient to reach the value written down (point
1), complete the cycle and go to DIAGNOSIS (see "new clutch position value"), then
add the necessary mm to enter the correct value.
