Note:
Fault finding procedure performed using a current clamp.
With the passenger compartment fan activated, fit a current clamp to the connection of earth between the battery
and chassis earth point, and use the CLIP tool to run command AC251 Heating resistor relay 2.
Does the current measured increase by at least 40 A when the command is run?
YES NO
With the passenger
compartment heating
resistors operating, carry
out a conformity check on
the injection, heating sub-
function (see 13B, Diesel
injection, Conformity
check).
Disconnect the passenger compartment heating resistor connector
(component 1113) and connect a test light between each of the connections
38LM and MAK and run command AC251 Heating resistor relay 2.
Does the test light illuminate?
NO YES
Replace the passenger compartment
heating resistor unit (component 1113)
(see MR 411, Mechanical, 61A, Heating,
Heating resistors: Removal - Refitting).Check the continuity of the 2 connections 38LM between
components 1113 and 1068.
Is the continuity correct?
NO YES
Continuity fault on
connection 38LM. If there
is a repair method
(see Technical Note
6015A, Repairing
electrical wiring, Wiring:
Precautions for repair),
repair or replace the
wiring.Re-run command AC251 Heating resistor relay 2. Check for + 12 V supply
on connections 3FB and BP9 of component 1068.
Are the supplies correct?
YES NO
Check the engine fuse
and relay box (see 16A,
Starting Charging).Run fault finding on the injection computer
for the heating element resistor 2 command
(see 13B, Diesel injection, Conformity
check).

Check the continuity on connection 38LL
between components 1113 and 1067.
Is the continuity correct?
YES
Re-run command AC250 Heating resistor
relay 1. Check for + 12 V between the chassis
earth and connections 3FB and BP9 of
component 1067.
Is there + 12 V?
YES
Run fault finding on the injection computer for
the heating element resistor 1 command
(see 13B, Diesel injection, Conformity check).
NOContinuity fault on connection 38LL. If there is
a repair procedure (see Technical Note

Note:
Fault finding procedure without using a current clamp.
Disconnect the passenger compartment heating resistor connector (component 1113) and connect a test light
between each of the connections 38LM and MAK and run command AC251 Heating resistor relay 2.
Does the test light illuminate?
YES NO
Replace the passenger
compartment heating resistor unit if,
at ambient temperature, the
resistance value between each of
connections 38LM and MAK of
component 1113, is not between:
0.55 and 0.75 Ω
(see MR 411, Mechanical, 61A,
Heating, Heating resistors:
Removal - Refitting).
The passenger compartment
heating resistors are correct, if the
fault is still present carry out a
conformity check on the injection,
heating sub-function (see 13B,
Diesel injection, Conformity
check).
Check the continuity of the 2 connections 38LM between
components 1113 and 1068.
Is the continuity correct?
YES NO
Continuity fault on connection
38LM. If there is a repair method
(see Technical Note 6015A,
Repairing electrical wiring,
Wiring: Precautions for repair),
repair or replace the wiring.
Check for + 12 V supply on connections 3FB and BP9 of
component 1068.
Are the supplies correct?
YES NO
Check the engine fuse
and relay box (see 16A,
Starting Charging).Carry out fault finding on the injection computer for heating resistor
relay 2 control (see 13B, Diesel injection, Conformity check).
