NOTESCheck that the vehicle is fitted with passenger compartment heating resistors.
No faults should be present or stored.
This command is for testing the operation of the passenger compartment heating
resistors.
The command lasts 7 seconds.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
Check for earth on connection NAM of
component 1113.
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.
With the command running, check for + 12 V feed on
connection 38LL of component 1113.
NO
Check for + 12 V on connection BP9 of
component 1067.
NO
YESCheck that the resistances, between
connections 38LL and MAK (track 2) and
between connections 38LL and MAK
(track 4) of component 1113, are equal to
infinity. Replace the passenger
compartment heating resistors if faulty.
YESCheck the insulation and continuity of
the following connection:
●Connection code 38LL between
components 1067 and 1113.
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.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
