Fault finding - Configurations and programming87B
This scenario is used to check the status of the key in the event of a blank or not blank UCH.
It tells you:
–if the key is blank (ET182 BLANK KEY),
–if the key is allocated to this vehicle or not (ET181 KEY ALLOCATED TO THE VEHICLE),
–If the key is a memory type (ET407 MEMORY KEY).

Equipment required
CLIP
Blank keyNO
This key is not blank but is allocated to the
vehicle, therefore the key is operational.
Check with the key statuses in the protection
sub-function (see conformity check in the
event of a fault). Key allocated to the vehicleYES
Memory keyYES/NO
Blank keyYES
This key is blank, allocate the key using
command SC015 KEY ALLOCATION to
allow it to be used on the vehicle. Key allocated to the vehicleNO
Memory keyYES/NO
Blank keyNOThis key is not blank, and it does not belong
to this vehicle. It is impossible to allocate this
key to the vehicle.
Or:
If the UCH is being replaced, this key belongs
to the vehicle but is no longer allocated, so
run command SC015 KEY ALLOCATION. Key allocated to the vehicleNO
Memory keyYES/NO

Functions available and operating mode
–Deadlocking (CF009)
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,

NOTESConditions for applying the fault finding procedure to stored faults:
–The fault is declared present after the ignition has been switched on.
If the fault is stored, switch off the ignition and check the F8 (15A) fuse of the UCH supply (component
code 645) on the passenger compartment fuse and relay box (component code 1016).
–Replace the fuse if necessary, clear the fault and switch on the ignition again.
–Request locking and then unlocking, then start the engine.
Check for + after ignition feed on connections AP43, BP15, APT, BP6, BP13, BP19, SP2, SP15 of
component 645.
Check for + 12 V accessories feed on connections SP2 and SP15 of component 645.
Check for earth on connections MAN and NAM 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.
Check that status ET045 “RF* signal received” is “Yes” by pressing the locking button on the key, if when
pressing the status is “No” check the battery and the conformity of the key.
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 REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
