Check for the supply and earth on the diagnostic socket (component 225) through the following connections: BP19
(+12 V), NAM and MAM (earth). If the checks are correct then move on to the next step, depending on the type of
sensor used:
1.Renault fault finding sensor (with wire connection only):
Check that the CLIP sensor is supplied through the computer's USB port and the diagnostic socket by checking
that the red diodes illuminate. If it is not, try with another cable, another sensor or another clip in order to determine
the defective component.
Check that the CLIP sensor communicates with the vehicle computers by checking that the two green LEDs on the
sensor light up. If it is not, check that the test conditions have been met ( + after ignition feed, vehicle selection
etc.) otherwise apply the electrical checks below.

2.Alliance fault finding sensor (with wireless connection possible):
Deal with the fault finding for each warning light in the following order of priority: from warning light 1 to warning
light 3.

–Initialisation or
connection fault.
Disconnect and
reconnect several
times. If the result
is not conclusive,
try with another
sensor.If off:
–Wireless connection:
Try connecting with a
USB cable. If the
warning light
illuminates orange,
then check the
configuration of the
wireless connection. If
it is not correct, call
Techline.
–Wire connection: Try
with another USB
cable or another CLIP
sensor or even another
sensor to determine
the faulty component.If warning light 3 is off
or red and warning
light 2 is on:
–in this case, during the
multiplex network test
check that the green
warning light flashes
and that the test
conditions have been
met (+ after ignition
feed, vehicle
selection, etc.)
otherwise apply the
electrical checks
below.If the
warning
light is on:
