CLUTCH 2
Note:
Status ET262 "Clutch 2" is applicable to the following sub-function:
–"Gear changes".
STATUS
DEFINITIONACTIVE: shows that clutch 2 is active.
INACTIVE: shows that clutch 2 is inactive.
NOTESSpecial notes:
Check (engine running) that status ET262 Clutch 2 is "Active", gear engaged 3, "R".
Conformity check with the engine running.
ACTIVE
INACTIVE
Check (engine running at idle speed and brake pedal depressed), lever in position "R",
ET013 "Gear engaged" = "R" or lever in position "M", ET013 "Gear engaged" = "3".
In the event of a fault, consult the interpretation of faults DF274 Clutch 2 solenoid valve
circuit and DF302 Clutch 2 pressure switch circuit.
If the fault is still present, contact Techline.
Status ET262 "Clutch 2" must be "INACTIVE" on all other gear ratios except:
–Lever in position "R", status ET013 "Gear engaged" = "R". (Only during a road test,
status ET262 "Clutch 2" is "Active", when status ET013 "Gear engaged" = "3", "5"
in mode "D" or when status ET013 "Gear engaged" = "5" in mode "M").
–Lever in position "M", ET013 "Gear engaged" = "3".
In the event of a fault, consult the interpretation of faults DF274 Clutch 2 solenoid valve
circuit and DF302 Clutch 2 pressure switch circuit.
If the fault is still present, contact Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

CLUTCH 3
Note:
Status ET263 "Clutch 3" is applicable to the following sub-function:
–"Gear changes".
STATUS
DEFINITIONACTIVE: shows that clutch 3 is active.
INACTIVE: shows that clutch 3 is inactive.
NOTESSpecial notes:
Check (engine running) that status ET263 Clutch 3 is active, gear engaged 4, 5, 6.
Conformity check during a road test.
ACTIVE
INACTIVE
Status ET263 "Clutch 3" becomes "ACTIVE" for the following engaged gears:
This status only arises during the road test, with the lever in position "D" or "M", ET013
"Gear engaged" = "4", "5", "6".
IMPORTANT
It is essential to have 2 people to perform these checks during a road test.
In the event of a fault, consult the interpretation of statuses DF275 Clutch 3 solenoid
valve circuit and DF303 Clutch 3 pressure switch circuit.
If the fault is still present, contact Techline.
Status ET263 "Clutch 3" must be "INACTIVE" on all other gear ratios except:
–Lever in "D" position, status ET013 "Gear engaged" = "4", "5", "6".
–Lever in "M" position, status ET013 "Gear engaged" = "4", "5", "6".
In the event of a fault, consult the interpretation of statuses DF275 Clutch 3 solenoid
valve circuit and DF303 Clutch 3 pressure switch circuit.
If the fault is still present, contact Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

TURBINE SPEED
Note:
Parameter PR007 "Turbine speed" applies to the following sub-functions:
"Gear changes".
"Torque activation".
PARAMETER
DEFINITIONThis parameter shows the gearbox turbine speed in rpm.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
No faults should be present or stored.
Conformity check with engine stopped and ignition on
PR007 = 0 rpm
In the event of a fault, consult the interpretation of fault DF038 Turbine speed sensor circuit.
Conformity check with engine running, engine coolant temperature > 80 ˚C
