NOTESThere must be no present or stored faults.
For statuses ET021 and ET022, the signal can be interpreted if the vehicle is
configured with 1000 W Passenger Compartment Heating Resistors or 1800 W
Passenger Compartment Heating Resistors.
For status ET023, the signal is interpretable if the vehicle is configured with RCH
1800 W.
In the event of a fault, check the operation of statuses ET015 Passenger compartment fan, ET017 Number of
RCH* required, ET018 Number of RCH* authorised by alternator, ET019 Number of RCH* authorised by
injection and ET020 Number of RCH* controlled.
Carry out fault finding on commands AC016 RCH* relay 1, AC017 RCH* relay 2 and AC018 RCH* relay 3.
Check the parameters needed to switch on the Passenger Compartment Heating Resistors; exterior temperature,
interior temperature, temperature setpoint on the heater control panel, alternator load, battery voltage.
If all the requisite conditions are consistent and the status remains INACTIVE, contact Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

BATTERY VOLTAGE
NOTESCheck that the battery terminals are correctly tightened.
Check the consistency between the battery voltage measurement from the multimeter and the value of PR004
Battery voltage.
Engine stopped: 11 V < X < 13.5 V.
Engine running: 10.5 V < X < 16 V.
If the voltage values are not consistent (greater than 0.3 V difference between the 2 values), check the connection
between the + battery feed and the Protection and Switching Unit.
If the values are consistent, run fault finding on the battery and charging circuit (see Technical Note 6014A,
Checking the charging circuit, 16A, Starting - Charging).
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.

ALP27 Locking/unlocking fault when pressing card button.
NOTESCheck that there is no APC or card in the card reader.
Check that no opening element is detected as open by the UCH (look at the symbol on
the instrument panel).
First carry out a function fault finding check.
Test with the other card.
Check the condition of the battery (inserted the wrong way round, flat, incorrect
model).
If the fault is still present after having carried out a test with the other card, it could be that:
–There may be radiofrequency interference in the area (ET066 Card button press received is NO for both
cards). Move the vehicle to try again.
–The UCH which has just been replaced does not have the correct part number (external or internal UCH
aerial). Use the correct UCH part number.
–If the vehicle is a Scenic II fitted with a tyre pressure monitoring system, check that the external UCH aerial
is connected correctly.
–Check that the UCH for the vehicle is not blank. Check that the UCH on the vehicle has not been used on
another vehicle.
Check that statuses ET066 Card button press received and ET067 Card button press recognised are YES
after pressing the card's lock or unlock button.
If not, apply the fault finding procedures for those statuses.
Check that statuses ET066 Card button press received and ET067 Card button press recognised are YES
after pressing the card's lock or unlock button.
If not, apply the fault finding procedures for those statuses.
Check that status ET014 Control power level is not APC.
If not, apply the fault finding procedures for this status.
Check that statuses ET041 Opening rear screen, ET042 Passenger's door, ET050 Tailgate/Boot, ET051 Rear
left-hand door, ET052 Rear left-hand door and ET053 Driver's door are CLOSED.
If not, apply the fault finding procedures for those statuses.
