To cut off + after ignition, proceed as follows:
–Disconnect the diagnostic tool.
–Press the Start button twice briefly (less than 3 seconds),
–See that the + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.
Faults
The current status of faults must be considered when the diagnostic tool is used following switching to + after
ignition (with no action on the system components).
For a present fault, handle the fault according to the procedure listed in the section on Interpretation of faults in
Workshop Repair Manual 372 Section 87B Passenger compartment connection unit.
There is no stored fault on the tyre pressure monitor.
Conformity check
The aim of the conformity check is to check statuses and parameters that do not produce a fault display on the
diagnostic tool when they are 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 features the fault finding procedure for statuses and parameters, and the conditions for checking them.
If a status is not operating normally or a parameter is outside permitted tolerance values, you should consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the check using the diagnostic tool is satisfactory but the customer complaint is still present, the fault should be
treated as a customer complaint.
A summary of the overall procedure to follow is provided on the following page
in the form of a flow chart.

PROGRAMMING THE FOUR VALVE CODES
IMPORTANT
Any repairs that involve replacement of a wheel sensor require knowledge of the recommendations
defined in Workshop Repair Manual 371 section 35.
–Inflate the four tyres to 3.8 bar.
–Using the diagnostic tool, establish dialogue with the UCH.
–Select the Repair mode menu
–Select the Programming menu
–Select line SC002 Programming the four valve codes under the Tyres function.
Display of stored codes and recognised valve set.
–Select the Valve set selection menu, then Summer or Winter.
–Confirm to obtain the table "valve programming conditions".
–Confirm by selecting next, which brings up the search for valve code menu.
–Excite each valve by holding the valve exciter on the tyre, just under the valve in question.
–Start with the front left-hand wheel.
–Wait for the new code to appear on the screen before moving on to the next valve.
–Program the codes in the following order:
Front left-hand Front right-hand Rear right-hand Rear left-hand
–Click on the "Confirm" button to transmit the codes to the UCH.
–Inflate the tyres to the recommended pressures.
–Carry out a road test: speed > 12 mph (20 km/h) for 10 minutes.
–Make sure no message appears on the instrument panel.
IMPORTANT
When swapping wheels over, reprogram the UCH for the new valve positions using the diagnostic tool and
programming the valve codes.
Then replace the colour rings in the locations noted on the label on the driver's door.

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.
