4. FAULT FINDING PROCEDURE (CONTINUED)
Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a
fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection of the connection
●Check that the connector is connected correctly and that the male and female parts of the connection are
correctly coupled.
Visual inspection of the area around the connection
●Check the condition of the mounting (pin, strap, adhesive tape, etc.), that the connectors are attached to the
vehicle.
●Check that there is no damage to the wiring trim (sheath, foam, adhesive tape, etc.) near the wiring.
●Check that there is no damage to the electrical wires at the connector outputs, in particular on the insulating
material (wear, cuts, burns, etc.).
Disconnect the connector to continue the checks.
Visual inspection of the plastic casing
●Check that there is no mechanical damage (casing crushed, cracked, broken, etc.), in particular to the fragile
components (lever, lock, openings, etc.).
●Check that there is no heat damage (casing melted, darker, deformed, etc.).
●Check that there are no stains (grease, mud, liquid, etc.).
Visual inspection of the metal contacts
(The female contact is called CLIP. The male contact is called TAB.)
●Check that there are no bent contacts (the contact is not inserted correctly and can come out of the back of the
connector). The spring contact of the connector when pulling the wire slightly.
●Check that there is no damage (folded tabs, clips open too wide, blackened or melted contact, etc.).
●Check that there is no oxidation on the metal contacts. Note:
Carry out each requested check visually. Do not remove a connector if it is not required.
Note:
Repeated connections and disconnections alter the functionality of the connectors and increase the risk of poor
electrical contact. Limit the number of connections/disconnections as much as possible.
Note:
The check is carried out on the 2 parts of the connection. There may be two types of connections:
–Connector / Connector
–Connector / Device

Description of gear lever positions (continued):
–"+": moving the gear lever towards this position enables the driver to shift up,
–“-”: moving the gear lever towards this position will enable the driver to shift down.
Description of the display:
This display is specifically for the sequential gearbox. It displays 4 types of information for the driver:
–displays the gear selected: 1, 2, 3, 4, 5, N or R,
–the pictogram displaying AUTO mode: this pictogram lights up when AUTO mode is selected,
–the “depress brake pedal” symbol: this symbol lights up when a driver action requires the brake pedal to be
depressed if the driver is not depressing the brake pedal. This symbol only lights up when there is an error (driver
actions without depressing the brake pedal = symbol lighting up),
–the sequential gearbox fault warning light: this lights up when the sequential gearbox computer detects a fault on
the sequential gearbox system.
General information about the operation:
Operation in MANUAL mode:
Manual mode allows the driver to select gears by moving the gear lever. However, in manual mode, the driver is not
completely free to do what he/she likes. This is why this mode is also called semiautomatic mode because the driver
is still assisted by the sequential gearbox computer in the following instances:
–when driving, shifting the lever towards the “+” position may result in underspeed. As a result, the sequential
gearbox computer forbids the driver's request,
–when driving, shifting the lever towards the “-” position may result in engine overspeed. As a result, the sequential
gearbox computer forbids the driver's request,
–when driving, as the overspeed threshold is approached, the computer automatically selects a higher gear,
–when driving, as the underspeed threshold is approached, the computer automatically selects a lower gear,
–when driving, if the vehicle speed reduces too quickly (brakes applied), the sequential gearbox computer can
order a downshift. Reminder:
Creep is only possible in first or reverse gears; it makes parking manoeuvres easier: if the brake pedal or
the handbrake is released, the vehicle moves forward by itself, without the driver having to accelerate.
Creeping is not possible in second gear.

Depress brake pedal symbol:
–The “depress brake” symbol lights up when there is:
–a request to change gear when stopped without the brake pedal applied,
–a request to start the engine with gear engaged without brake pedal applied,
–a request to select N when driving without brake pedal applied,
–a request to select AUTO, with the vehicle stationary, the engine running and 2
nd gear engaged.
–Depress brake pedal symbol goes out:
The symbol goes out if the driver depresses the brake pedal or after a delay.
In the event that the driver makes a request causing the gear requested to flash and the symbol to be displayed at
the same time, they will be synchronised and last for the same period of time.
Fault warning light:
This warning light comes on when a fault is detected by the sequential gearbox computer.Note:
If, while the symbol is lit, the driver depresses the brake pedal, the symbol will go out and the display will return to
its previous status (the lever request is not registered).
