CC.0 : Short circuit to earth
CO.1 : Short circuit or open circuit to + 12 V
NOTESConditions for applying the fault finding procedure to stored faults:
Apply this fault finding procedure if the fault appears as present or stored again after:
–clearing the fault and switching the ignition off then back on.
Special notes:
The solar sensor (a little black button) is located on top of the dashboard, on the
windscreen side.
Check that the solar sensor is not "shaded" by any objects (nothing should be placed on top of the sensor).
Check the connection and condition of the solar radiation sensor connector.
Replace the connector if necessary.
Disconnect connector A (12-track) from the climate control computer in order to check the insulation,
continuity and absence of interference resistance of the connections:
Computer connector A track 4 Track 2 of the solar radiation sensor
Computer connector A track 12 Track 1 of the solar radiation sensor
Track 5 of the internal temperature sensor
Repair if necessary.
With the ignition on, the solar radiation sensor electrically connected and the climate control panel on, ensure
that the solar radiation sensor supplies a voltage (signal) to the climate control computer.
To find out the voltage that the sensor should be supplying as a function of solar radiation intensity, consult the
interpretation of this parameter (Interpretation of parameters section).
If the fault is still present, replace the solar radiation sensor.
AFTER REPAIRClear the fault memory.
Deal with any other faults.

Fault finding – Interpretation of statuses
ET007
COMPUTER + AFTER IGNITION FEED
NOTESNone.
This status shows the + 12 V after ignition feed supplied by the Protection and Switching Unit.
When the ignition is off, the status displays: ABSENT.
When the ignition is on, the status displays: PRESENT.
If the fault is still present, carry out fault finding on the Protection and Switching Unit: Check that status
ET003 After ignition relay control is working correctly and check that fault DF001 After ignition relay control
circuit is not present.
Carry out any repairs necessary (see corresponding fault finding procedures).
If the fault is still present: disconnect connector A (12-track) from the climate control computer to check the
insulation, continuity and absence of interference resistance of the following connections:
Computer connector A track 10 + accessories feed (7.5 A fuse in the Protection and
Switching Unit)
Computer connector A track 11 + before ignition feed (20 A fuse of the UCH)
Computer connector A track 6 Earth (left-hand dashboard beam)
Repair if necessary.
If the connections are correct and the climate control computer is correctly supplied but the fault is still present:
carry out fault finding on the electric charge circuit.
AFTER REPAIRRepeat the conformity check from the start.

BATTERY VOLTAGE
NOTESNone.
This parameter specifies the supply voltage of the climate control computer.
This parameter should indicate a voltage equal to: 10.5 < X < 14.4 V.
If the voltage is not within the specified range, disconnect connector A (12-track) of the climate control
computer to check the insulation, continuity and absence of interference resistance of the connections:
Computer connector A track 10 + accessories feed (7.5 A fuse in the Protection and
Switching Unit)
Computer connector A track 11 + before ignition feed (20 A fuse of the UCH)
Computer connector A track 6 Earth (left-hand dashboard beam)
Repair if necessary.
If the connections are correct but the fault still persists, perform fault finding on the charging circuit.
AFTER REPAIRRepeat the conformity check from the start.

With the distribution motor removed, operate the distribution
flaps manually by turning the centre of the control from one limit
to the other (the limits are V shaped).
Does the flap cover the whole range of movement, without
any areas of resistance?
YES
Remove the footwell vent ducts (lower ducts) to check that the
lower flap control linkages are present and correctly fitted (they
are connected to the upper flaps). Also ensure that lower flaps
move when the distribution flap manual control is operated.
Do the footwell (lower) distribution flaps move when the
distribution flaps are controlled?
YES
If the fault is still present with the distribution motor dismantled
and connected, carry out a motor command using the distribution
buttons on the control panel: switch the distribution flap to
demisting position (value 100%) then switch the distribution
setting to air vent position (value 0%).
Is the distribution motor operating?
YES
Remove the dashboard and visually check that when the
distribution flaps are moved manually (by turning the centre of the
control), moving the control does in fact move the distribution
flaps.
Is there movement?
YES
End of fault finding procedure.
NO
NO
NO
NORemove the dashboard to check
that nothing is preventing the
flaps from moving. Repair
(remove any foreign bodies
which may be blocking the flaps
and grease the centre of the flap
control mechanism). Replace
the distribution - ventilation unit if
it is not possible to repair it.
If the mountings of the lower flap
control linkages are not
damaged: resecure the linkages
and grease them slightly. If a
repair is not possible or if the
mountings are damaged:
replace the distribution -
ventilation unit.
Apply the fault finding procedure
for fault DF012 Distribution
motor circuit.
Replace the distribution -
ventilation unit.
AFTER REPAIRPerform a complete check using the diagnostic tool.
