NUMBER OF RCH* CONTROLLED
NOTESThere must be no present or stored faults.
The maximum number of passenger compartment heating resistors controlled will be
the minimum number indicated by statuses ET017, ET018, ET019.
Special note:
The UCH controls the passenger compartment heating resistor relays according to the
authorisation from the injection computers and Protection and Switching Unit.
The status, depending on the conditions, will be 0, 1, 2, 3, or 4.
The passenger compartment heating resistor control conditions are:
–Heater motor running.
–Battery voltage > 12 V.
–Interior temperature < 10˚C.
–User temperature setpoint in warm position (> 20˚C).
–PR002 External temperature < 5˚C.
–ET015 Passenger compartment fan ACTIVE.
–ET018 Number of RCHs authorised by alternator > 0.
–ET019 Number of RCH* authorised by injection computer > 0.
–PR010 (UPC) Alternator charge < 70%.
If all the conditions are satisfied, and depending on the air conditioning function program, the UCH controls the
Passenger Compartment Heating Resistors needed to provide the service.
Check that these statuses and parameters are working properly.
In the event of a fault, refer to the interpretation of these statuses and parameters.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

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.

REAR RIGHT-HAND DOOR CHILD SAFETY LOCK
NOTESNo faults should be present or stored.
Check that configuration LC035 Child safety lock is WITH, if not perform configuration
using specific command SC016 Child safety lock (see Configurations and
programming). Status only visible if Vdiag 4C, 4D, 4F and 50 UCH.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
IMPORTANT
After disconnecting the battery, there may be an inconsistency between a request on the switch and the status of
one or two lock(s).
In this case, deactivate and reactivate the switch until the warning light comes on when the switch is pressed.
Check the condition and connection of the lock connector (broken, bent, oxidised tabs).
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the condition and connection of the PP2 connector of the UCH (tabs broken, bent, oxidised).
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check for earth on connection MZ of component 139 or on connection MAQ of component 138.
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
●Connection code 87A between components 645 and 139.
●Connection code 87B between components 645 and 138.
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.
Replace the faulty lock.
If the fault is still present, contact Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
