Fault finding - Introduction87B
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.
Continuity, insulation and 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.

1 - Write the VIN, using command VP004 Write VIN.
2 - Program the UCH using command SC004 UCH programming.
3 - Configuration of the UCH (in the Configuration and programming menu) using the following commands:
CF031 Calibration,
CF019 Type of heating and air conditioning system,
CF028 Engine type,
CF171 Temperature display,
CF029 External temperature sensor,
CF173 One-touch windows/sunroof (SR)*.
CF032 See-me-home lighting,
CF021 Front fog lights,
CF014 Daytime running lights
CF193 Automatic headlight function,
CF194 Automatic wiping function,
CF035 Rain/light sensor,
CF191 Wiper intermittent speed ring,
CF024 Hazard warning lights activated by ABS,
CF108 Locking via the RAID,
CF009 Deadlocking,
CF192 Central door locking,
CF195 Type of key,
CF229 Alarm.
4 - Key allocation, using command SC015 Key allocation.
5 - Configuration of the multiplex network is used to define (in the UCH) the different computers present and which
support fault finding on the multiplex network.

UCH programming procedure
–Establish dialogue with the UCH.
–Select the "Repair mode" menu.
–Select the Secure programming menu.
–Select line SC004 Program UCH.
Follow the instructions on the CLIP diagnostic tool.
In "not connected" mode, when the CLIP diagnostic tool displays the programming key, make a note of this key
and the VIN.
To obtain the immobiliser code, see Technical Note 5037A, Code delivery procedure.
Operations to be carried out after programming the UCH
➡ Enter the vehicle's VIN to the computer using command VP004 Enter VIN.
Make sure that all the keys can lock and start the vehicle.
➡ After programming the UCH, allocate all the keys using command SC015 Allocate key.
➡ Configure the equipment as present or not present on the vehicle using the commands
(see Configurations and Programming). SC004

IMPORTANT
Do not interrupt the procedure when it is in progress.
If it is interrupted, restart the procedure; a new programming key will be displayed.
IMPORTANT
In "not connected" mode, the programming key can only be used for a limited amount of time, as indicated by the
CLIP diagnostic tool. After this time, the programming key and associated immobiliser code are no longer valid.
The operation must be restarted from the beginning.

Key allocation procedure
–Establish dialogue with the UCH
–Select the Repair mode menu
–Select the Secure programming menu
–Select line SC015 Allocate key.
The procedure for allocating keys is divided in two parts:
1Key insertion stage.
2Key allocation stage.
1 - Key insertion stage
Clip requests that the keys to be allocated are inserted.
Insert ALL the keys to be allocated (old and new blank keys); any keys not inserted at this stage will be rejected in
the Key allocation stage and the operation will have to be restarted from the beginning.
Once all the keys are inserted, the Clip diagnostic tool displays the programming key.
To obtain the immobiliser code, see Technical Note 5037A, Code delivery procedure.
2 - Key allocation stage:
Continue the procedure following the instructions on the CLIP diagnostic tool.
Once the keys have been allocated, make sure that all the keys can lock and start the vehicle.SC015
CONTINUED
IMPORTANT
In "not connected" mode, once the tool has issued the programming key, the user has a limited amount of time in
which to enter the immobiliser code.
If this time expires, the CLIP diagnostic tool displays the message "Time expired. Restart the procedure''.
IMPORTANT
In "connected" mode, the exchange of the programming key and the entry of the immobiliser code is done
automatically.
If the connection parameters are not met, "connected" mode switches automatically to "not connected" mode.
IMPORTANT
The programming key can only be used for a limited time, as shown by the Clip diagnostic tool. After this time,
the programming key and associated immobiliser code are no longer valid. The operation must be restarted from
the beginning.

This function enables you to disable the interior door opening control. This function is activated by a second locking
request from the key or the electric central locking switch.
This function is only available on vehicles fitted with a top of the range UCH.
–Hazard warning lights activated by ABS (CF024)
This function is available for all countries except Brazil, Finland, Great Britain, Japan and Sweden.
For Brazil, Great Britain, Japan, Sweden and Finland configure NONE.
For other countries, configure WITH.
In the event of braking causing rapid deceleration, the ABS computer transmits an activate hazard warning lights
request via the multiplex network to the UCH.
–New vehicle storage mode (LC041 New vehicle storage mode)
If this mode is activated, consult the command, see LC041 "New vehicle storage mode" and contact the Techline.
–Daytime running lights
This configuration automatically activates the side lights and dipped beam headlights when the engine is running,
without the driver using the lighting controls.
To be used in accordance with legislative requirements.
CF031 Calibration:
When replacing the UCH computer, perform this configuration.
This command lasts approximately 30 seconds.

PRESENT
OR
STOREDUCH
1.DEF : Internal electronic fault
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the ignition is switched off and back on.
If the fault is stored, clear the fault, switch off the ignition and disconnect the F8 (15A) fuse of the UCH supply
(component code 645) on the passenger compartment fuse and relay box (component code 1016).
–Refit the fuse and switch the ignition back on.
–Request locking and then unlocking, then start the engine.
Check the condition and connection of the PE1, PE2 and PE3 connectors of the UCH (component code 645)
(tabs pushed back, oxidised, broken).
If the connector(s) are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check for + after ignition feed on connection AP43 of component 645.
Check for + accessories feed on connection SP2 (for vehicles fitted with a manual gearbox) or SP15
(for vehicles fitted with a sequential gearbox) of component 645.
Check for earth on connection NAM of component 645. Check the earth on connection MAM of component 645.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault reappears as stored, contact Techline.
If the fault does not reappear, switch the lighting, wipers, vehicle locking and climate control request controls on
and off several times, then read the faults again.
If the fault is still present. Do not operate on the computer, contact Techline.
AFTER REPAIRIf the computer has been replaced (at the request of the Techline): reconfigure the new
UCH (see Configurations and programming).
Deal with any other faults.
