If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the wiring, otherwise replace it.
Using the diagnostic tool, run command AC016 Selection solenoid valves and check that the selection is
made correctly by carrying out a listening test.
If the selection is not made correctly, replace selection solenoid valve 1 (see MR 411 Mechanical, 21B,
Sequential gearbox, Solenoid valves: Removal - Refitting).
If the fault is still present, contact the Techline.

1.DEF: Clutch inconsistency upon gear change
NOTESPriorities when dealing with a number of faults:
In the event of a number of faults, deal with faults DF068 Clutch position sensor
circuit, DF071 Clutch solenoid valve circuit and DF254 Clutch temperature.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present following harsh use of the clutch (prolonged hold on a
hill, PR095 Clutch temperature ≥ 248˚C).
Special notes:
Fault warning light comes on,
When PR095 Clutch temperature ≥ 248˚C, the buzzer is activated.
Check that the clutch is not slipping by performing a road test, driving with a low load and then up or down an
incline.
If the clutch slips, pull away several times with a low load and check if PR096 Clutch progressivity changes.
If the fault is still present, replace the clutch (see MR 411 Mechanical, 21B, Sequential gearbox).
