Components involved<br />
• Hydraulic power and Quick disconnect.<br />
• Clutch solenoid valve.<br />
• PLCD clutch sensor.<br />
• Levers control.<br />
• TCU.<br />
• Brake switch.<br />
Practical checks<br />
• Check that hydraulic power is present and that the Quick disconnect is connected.<br />
• Shifting a <strong>gear</strong> with the engine off, check that the clutch position signal displayed<br />
by means of the Ferrari tester shows that the clutch opens after PIS and the closes<br />
once again (see paramenters through the Ferrari Tester).<br />
• Check the lever controls.<br />
• To understand if actuation is being performed or if the sensor is not responding<br />
properly, check the control current for the clutch solenoid valve during <strong>gear</strong>-shifting.<br />
• Using the Ferrari Tester, check that the pressed brake signal is correct.<br />
When everything is working properly<br />
• During <strong>gear</strong>-shifting, even with the engine off, the clutch must open after PIS and<br />
then close again after engaging the <strong>gear</strong>.<br />
Gear<strong>box</strong> Actuation<br />
Signs of possible problems<br />
• The system does not shift <strong>gear</strong>s.<br />
• The <strong>gear</strong> engaged is wrong.<br />
Components involved<br />
• Clutch actuation<br />
• Engagement and selection solenoid valves.<br />
• Engagement and selection position sensor.<br />
• TCU.<br />
• Pick-up and revolution signals (only if there's no actuation with the engine running).<br />
Practical checks<br />
• Check the clutch actuation.<br />
• When requesting a <strong>gear</strong>-shift, check the control currents for the solenoid valves<br />
involved.
