For diesel vehicles fitted with
passenger compartment heating
resistors, check that they do not
operate when the engine is hot
(temperature > 50 ˚C).
Disconnect the Passenger
compartment heating resistors
connector (component 1113) and
connect a test light between
connections 38LL and MAK.
Does the test light illuminate?
NO
Disconnect the Passenger
compartment heating resistors
connector (component 1113) and
connector a test light between each
of the connections 38LM
and MAK.
Does the test light illuminate?
NO
End of fault finding procedure.
Check the continuity and insulation to + 12 V of connection
38LL between components 1113 and 1067.
Is the connection OK?
YES NO
YESRun fault finding on the
injection computer for the
heating element resistor 1
command (see 13B, Diesel
injection, Conformity
check, Heating sub-
function ).
If the control is correct,
replace the relay
(component 1067).Fault on connection
38LL, if there is a repair
procedure, repair the
wiring (see Technical
Note 6015A, Repairing
electrical wiring,
Wiring: Precautions for
repair), otherwise
replace the wiring.
Check the continuity and insulation to + 12 V of the
2 connections 38LM between components 1113 and 1068.
YES Is the connection OK?
YES NO
Run fault finding on the
injection computer for the
heating element resistor 2
command (see 13B, Diesel
injection, Conformity
check, Heating sub-
function).
If the control is correct,
replace the relay
(component 1068).Fault on connection
38LM, if there is a repair
procedure, repair the
wiring (see Technical
Note 6015A, Repairing
electrical wiring,
Wiring: Precautions
for repair), otherwise
replace the wiring.
