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.
