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.
