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
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Tactile inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or to another wire.
If a fault is detected, repair or replace the wiring harness.

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.
