C42: CHECK FOR OPEN CIRCUIT BETWEEN THE CONTROL PANEL FOR THE CLIMATE
CONTROL SYSTEM AND THE INSTRUMENT CLUSTER
PINPOINT TEST D : MALFUNCTION OF THE RECIRCULATED AIR FLAP
NOTE: The recirculated air flap is actuated by means of a DC motor. This is activated for
a maximum of 7 seconds by the control panel for the climate control system following
actuation of the recirculated air button. Opening and closing of the recirculated air flap is
performed by reversing the polarity of the applied voltage.
NOTE: "Recirculated air" mode is not available when the "Defrost/demist windscreen"
function is active.
TEST CONDITIONS
D1: CHECK THE VOLTAGE AT THE AIR RECIRCULATION FLAP ACTUATOR
Switch on the blower.
4
Switch on the air-conditioning system.
5
Measure the voltage at the instrument cluster,
6
connector C809, between pin 23, circuit 15S-FA38
(GN/RD), wiring harness side and ground.
Does the meter display battery voltage?
Yes
CHECK and if necessary RENEW the instrument
cluster. CHECK the operation of the system.
No
GO to C42.
Ignition switch in position 0.
1
Disconnect Connector C380 from the control panel
2
for the climate control system.
Measure the resistance between the control panel
3
for the climate control system, connector C380, pin
9, circuit 15S-FA38 (GN/RD), wiring harness side
and the instrument cluster, connector C809, pin 23,
circuit 15S-FA38 (GN/RD), wiring harness side.
Is a resistance of less than 2 Ohm registered?
Yes
GO to C28.
No
LOCATE and REPAIR the break in circuit 15S-FA38
(GN/RD) between the control panel for the climate
control system and the instrument cluster with the
aid of the Wiring Diagrams. CHECK the operation of
the system.
DETAILS/RESULTS/ACTIONS
Ignition switch in position 0.
1
Disconnect connector C375 from air recirculation
2
flap actuator.
Ignition switch in position II.
3
Set the air distribution to footwell.
