CO.0/ CC.1
NOTESNone
Check the condition and position of the 30 A fuse for the pump in the engine compartment.
Repair if necessary.
Check the connection and condition of the connectors of components 119 and 1059 and the 24 track
intermediate connector located on the hydraulic unit.
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connectors; otherwise, replace the wiring.
Check the continuity and insulation to earth and + 12 V on the following connections:
●Connection code 5HN,
●Connection code 5HX,
●Connection code 5AD,
between components 119 and 1059.
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.
If the fault is still present, replace the oil pressure sensor on the Sequential gearbox (see MR 411, Sequential
gearbox, solenoid valve unit pressure sensor, Removal refitting).
AFTER REPAIRDeal with any faults detected by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESNone
Check the level of oil in the discharged accumulator, refer to the interpretation of command AC081 Discharge
pressure accumulator.
Check the condition and position of the 30 A fuse for the pump in the engine compartment.
Use command AC012 “Hydraulic pump relay” with the diagnostic tool and check that the pump assembly is
working. If the pump is not working, perform the necessary repairs.
If the fault is still present, replace the oil pressure sensor (see MR 411, Sequential gearbox, solenoid valve unit
pressure sensor, Removal refitting).
Switch off the ignition.
Switch on the ignition again and carry out a new check using the diagnostic tool.
Replace the pump assembly if the fault reappears (see MR 411, Sequential gearbox, pump assembly,
Removal refitting).
AFTER REPAIRDeal with any faults detected by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

STOREDGEAR SELECTION IMPOSSIBLE
1.DEF : Impossible to select gear
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after an engine start attempt and an attempt to engage a
gear.
Special note:
–Fault warning light comes on.
–Neutral engaged immediately.
Check that there are no engagement or selection sensor faults.
If faults associated with these components are present, deal with these first.
Check that the selection control lever is correctly clipped to the hydraulic unit (see MR 411, 21B, Sequential
gearbox).
Carry out the necessary repairs.
Check that there is no water in the sequential gearbox oil.
Repair if necessary.
Clear the computer fault memory using command RZ001 "Stored fault(s)".
Carry out the programming procedure for the "Hydraulic unit - gearbox kit (without
clutch) or Clutch or gearbox + Clutch" (see "Replacement of components").
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults detected by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
If a gear was engaged when there is a request to start the engine check the oil level in the sequential gearbox
circuit.
Check the operation of the brake pedal switch as well as the condition of the gear lever switches (consult the
interpretation of statuses: ET043 “Lever switch no. 0”, ET044 “Lever switch no. 1”, ET045 “Lever switch
no. 2” and ET046 “Lever switch no. 3”).
Ensure that the cylinder and the clutch fork are operating correctly (damage, seizing, part breakage, etc.).
AFTER REPAIRClear the computer fault memory. Switch off the ignition and wait 20 seconds.
Carry out a road test followed by another check with the diagnostic tool.
