Note:
Fault finding procedure without using a current clamp.
For vehicles equipped with Passenger compartment heating resistors and climate control, check that the
climate control computer is correctly configured by reading the following configurations (reconfigure the computer
if necessary):
–For the climate control computer, parameter LC044 Heating resistor type should display 900 W.
Disconnect the passenger compartment heating resistor connector (component 1113) and connect a test light
between connections 38LL and MAK and run command AC250 Heating resistor relay 1.
Does the test light illuminate?
YES NO
Replace the passenger
compartment heating resistor unit if,
at ambient temperature, the
resistance value between
connections 38LL and MAK of
component 1113, is not between:
0.55 and 0.75 ΩΩ Ω Ω
(see MR 411,
Mechanical, 61A, Heating,
Heating resistors:
Removal - Refitting).
Connect a test light between connections 38LL of component 1113
and the chassis earth and run command AC250 Heating resistor
relay 1.
Does the test bulb illuminate?
NO YES
Earth fault on component
1113. If there is a repair
method (see Technical Note
6015A, Repairing electrical
wiring, Wiring: Precautions
for repair), repair or replace
the wiring.
B
Check the continuity on
connection 38LL between
components 1113 and 1067.
Is the continuity correct?
NO YES
Continuity fault on connection 38LL. If there is a repair
method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair
or replace the wiring.D
