Fault finding – Introduction
3. REMINDERS
Procedure
To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (+ after ignition forced
setting).
Proceed as follows:
–With the vehicle card in the card reader (scenario 1 keyless vehicle, entry level, without hands-free and
scenario 2, top of the range, hands-free),
–Press and hold start button (longer than 5 seconds) with start-up conditions not fulfilled,
–Connect the diagnostic tool and perform the required operations.
To cut off + after ignition, proceed as follows:
–Disconnect the diagnostic tool,
–Press the start button twice briefly (less then 3 seconds),
–Ensure that the + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.
Faults
Faults are declared 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 had fault finding performed on them within the
current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is used after the
+ after ignition feed has been supplied (without acting on the system components).
For a present fault, apply the method described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply 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 faulty component,
–the condition of the wires (melted or cut insulation, wear).
Conformity check
The conformity check is designed to check the states and parameters which do not display any faults on the
diagnostic tool when inconsistent. This phase therefore allows:
–Diagnoses of faults that do not have a fault display, and which may correspond to a customer complaint.
–Checks to ensure that the system is operating correctly and that there is no risk of a fault reappearing after
repairs.
This section gives the fault finding procedures for states and parameters and the conditions for checking them.
If a state is not behaving normally or a parameter is outside permitted tolerance values, you should refer to the
corresponding fault finding page.Note:
The left-hand and right-hand Xenon bulb computers are powered when the dipped
headlights are lit. Fault finding procedures can only be carried out on them after the
ignition has been switched on in fault finding mode (+ after ignition forced setting) and the
dipped headlights are on.
