Fault finding - Introduction85A
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.

ALP 18 No wiping when it rains
NOTESOnly check this customer complaint after a complete check with the diagnostic tool.
Check in particular the correct functioning of statuses ET077 "Wiper stalk position"
and ET114 "Wiper request by rain sensor" in the UCH.
Note:
If the exterior temperature is below 5 ˚C, automatic wiper action will be blocked, to
avoid damaging the wiper blades if they are frozen.
STEP 1
Place the command in the intermittent position to activate automatic wiping.
If necessary explain to the customer how this function works.
STEP 2
Check whether the vehicle has a rain / light sensor. If the vehicle does not have a rain / light sensor, explain to the
customer that this is normal, and that the vehicle does not have this feature.
Check that the vehicle is configured with a rain / light sensor.
Check that LC044 "Rain/light sensor" displays "Present". If not, carry out CF035 "Rain/light sensor".
Check that LC096 "Automatic wiper function" displays "With". If not, carry out CF194 "Automatic wiper
function".
Check that LC095 "Automatic headlight function", displays "With". If not, carry out CF193 "Automatic
headlight function".
STEP 3
Check that the windscreen is clean and in good condition (no cracks, bonded correctly, etc.).
Check that the sensor is present and correctly positioned.
Check that the windscreen is the correct type.
AFTER REPAIRCarry out a complete check with the diagnostic tool.

ALP 19No change in wiper speed after activating the wiper intermittent
speed ring
NOTESOnly check this customer complaint after a complete check with the diagnostic tool.
Check in particular the correct functioning of statuses ET077 "Wiper stalk position"
and ET114 "Wiper request by rain sensor" in the UCH.
Note:
In order for intermittent wiping to function, the ignition must be on and the wiper
intermittent speed ring should be at least in position "1". With each change of position
for the wiper intermittent speed ring, the windscreen wiper blades should carry out
one movement.
If the exterior temperature is below 5 ˚C, automatic wiper action will be blocked, to
avoid damaging the wiper blades if they are frozen.
STEP 1
Check that the vehicle is fitted with a wiper intermittent speed ring.
Check that LC094 "Wiper intermittent speed ring" displays "With". If not, carry out CF191 "Wiper intermittent
speed ring".
If CF191 "Wiper intermittent speed ring" displays "With", check in the ICM application (Shared World
Information) that the vehicle does indeed have this fitted.
STEP 2
Ensure the correct functioning of status ET077 "Wiper stalk position". In the event of a fault consult status
interpretation ET077 "W iper stalk position".
Ensure the correct functioning of status ET096 "Wiper intermittent position". In the event of a fault consult
status interpretation ET096 "Wiper intermittent position".
Ensure that the park position is not presenting a fault (DF097 "Windscreen wiper park position").
STEP 3
Check that the vehicle is configured with a rain / light sensor.
Check that LC044 "Rain/light sensor" displays "Present". If not, carry out CF035 "Rain/light sensor".
Check that LC096 "Automatic wiper function" displays "With". If not, carry out CF194 "Automatic wiper
function".
Check that LC095 "Automatic headlight function", displays "With". If not, carry out CF193 "Automatic
headlight function".
AFTER REPAIRCarry out a complete check with the diagnostic tool.
