5. FAULT FINDING LOG
You will always be asked for this sheet:
●when requesting technical assistance from the Techline.
●for approval requests when replacing parts for which approval is obligatory.
●to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any damage or injury:
–Make sure the battery is properly charged to avoid damaging the computers with a low load.
–Use the appropriate tools. IMPORTANT!IMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the procedure, enables you to keep
track of the procedure which is carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG FOR EACH FAULT
FINDING PROCEDURE.

Following a battery cut-off,
it is normal that all

pressure values 0 bar.
Perform a road test so that
the valves emit their true

values.
It may be that the
temperatures of all the
tyres are not exactly the
same, depending on the
load distribution and
whether or not they are
exposed to sunlight. PR004:Front right-hand

NOTESThere must be no faults present
Carry out this fault finding procedure after finding a discrepancy between these
parameters on the display.
IMPORTANT
After a battery cut-off, the parameters will display a default value (0 bar). By creating a tyre leak or using
a road test, force each valve to transmit in order to see the actual pressure levels measured by the
valves during the fault finding procedure.
In all cases, check that the pressures displayed on the diagnostic tool actually match the pressure-gauge
readings (to within 0.2 bar).
Parameters PR003 to PR006 display incorrect values (other than 0 bar)
Check the pressure with another pressure gauge to see if the variation is due to the valve or the pressure
gauge.
Inflate the tyres to the recommended pressure by taking into account the variation of the pressure gauge if
necessary, or replace the valve if it is defective.
After programming, repeat the fault finding procedure from the beginning.
AFTER REPAIRRepeat the check from the start.

NOTESNone
Try the diagnostic tool on another vehicle.
Make sure the tool update version is more recent than CD-ROM No. 32.
Check:
–the connection between the diagnostic tool and socket (connection and cable in good condition).
–the computer power supply
–the engine and passenger compartment fuses.
Make sure that the CLIP sensor is fed by tracks 16 (+ 12 V), 4 and 5 (earth) of the diagnostic socket, which
can be seen by the two red warning lights on the sensor lighting up.
Make sure that the CLIP sensor is connected to the computer's USB port.
Make sure that the CLIP sensor is communicating properly with the vehicle's computers; this can be seen by
the two green diodes on the sensor lighting up.
Check the following tracks on the diagnostic socket:
track 1 + After ignition feed
track 16 + battery feed
tracks 4 and 5 Earth
Repair if necessary.
Check the continuity, insulation and absence of interference resistance on lines:
multiplex line H (diagnostic socket track 6)
multiplex line L (diagnostic socket track 14)
With a multimeter, make sure that the voltages at the diagnostic socket terminals are:
–2.5 V between CAN H (track 6) and the earth (tracks 4 and 5)
–2.5 V between CAN L (track 14) and the earth (tracks 4 and 5)
If dialogue with the UCH still has not been established after all the checks, contact your Techline.
AFTER REPAIRCheck that no faults are still present.
Check that the system is operating correctly.
