Fault finding - Introduction21B
Faults
Faults are declared as either present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but have not been diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
after the + after ignition feed (without any system components being active).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the instructions in the Notes section.
If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the fault
If the fault is not confirmed, check:
–the electrical lines which correspond to the fault,
–the connectors on these lines (corrosion, bent pins, etc.),
–the resistance of the component detected as faulty,
–the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because the
data is inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint.
–check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
customer complaint.
A summary of the overall procedure to follow is provided on the following page
in the form of a flow chart.

Fault finding - System operation21B
Lever operation:
–Each time the lever is moved, it returns to the “S” position automatically.
–When the vehicle has stopped and the engine is switched off and the key is in + after ignition feed position, lever
movements will only be registered if the driver depresses the brake pedal. In this case, all gears are available. The
number of gear changes possible is unlimited.
–When the vehicle has stopped and the engine is running, lever movements will only be registered if the driver
depresses the brake pedal. In this configuration, only gears N, 1, 2 and R are available.
–Position N only allows neutral to be engaged if the driver depresses the brake pedal.
–Position R enables reverse gear to be engaged. Reverse gear will only be engaged if the vehicle has stopped and
if the driver depresses the brake pedal. Engaging reverse when driving is prevented by the sequential gearbox
computer.
Display operation:
AUTO repeater
–As the display has an AUTO (A) symbol, it is possible to display the gear engaged at the same time as
AUTO mode.
Gear selection display
–Vehicle stopped or almost stopped: A new gear will only be displayed after confirmation that the gear has
really been engaged in the gearbox.
–Vehicle being driven: the change in the status of the display will depend on the driving mode selected:
In AUTO mode: simultaneous display of the AUTO mode and the gear engaged.
In MANUAL mode: engaged gear is displayed.
Display programming when gears cannot be engaged
–When a request would lead to engine overspeed or underspeed: the requested gear flashes then initial
gear reappears. Flashing ends after a delay.
–When there is a mechanical fault: application of the “retry” (1) program by the computer.
During retry: the requested gear flashes; then, the engaged gear is displayed on the instrument panel at
the end of the retry period. This program cannot be applied to neutral because the “N” position cannot
flash on the instrument panel; it remains lit.
(1) “RETRY”: If there is a mechanical fault engaging a gear (lower or higher), the computer will detect this
and will attempt to re-engage twice more; if this does not work, the requested gear will flash on the
instrument panel display and the gearbox will return to the gear used prior to this request.
