NOTESNone.
Try the diagnostic tool on another vehicle.
Check:
–the connection between the diagnostic tool and the diagnostic sensor (wiring in good condition),
–the connection between the vehicle's diagnostic sensor and the diagnostic socket (cable in good condition),
–the injection, engine and passenger compartment fuses.
Check for + 12 V battery on track 16, and + 12 V after ignition feed on track 1 and an earth on track 5 and
on track 4 of the diagnostic socket.
Repair if necessary.
Disconnect the connector from the climate control computer in order to check the insulation, continuity and
the absence of interference resistance of the following connections:
Climate control computer 12-track connector:
Track 11 + before ignition (see the vehicle wiring diagram)
Track 10 + accessories feed (see the vehicle wiring diagram)
Track 6 Earth
Track 7 Track 6 of the diagnostic socket (CAN H)
Track 1 Track 14 of the diagnostic socket (CAN L)
Repair if necessary (see the vehicle wiring diagram).
AFTER REPAIRPerform a complete check using the diagnostic tool.

ALP 5 No passenger compartment ventilation
NOTESOnly consult this customer complaint after a complete check using the
diagnostic tool.
Special notes:
The 2 x 5-track intermediate connector is located on the LH side of the distribution /
ventilation unit (behind a plastic cover) and the passenger compartment fan control
module is located slightly higher up, below the heater matrix pipes.
Check that the fusesare in good condition.
Using the diagnostic tool, check that the passenger compartment fan
control setting given by the computer varies from 0 to 100% by checking
parameter PR019 Passenger compartment fan PWM setpoint
(refer to the interpretation of this status).
Does the value vary?
YES
Check that the control voltage (PWM) (modulated control voltage) of the passenger
compartment fan power module varies between 5 and 12 V (from 0 to 100%) by
measuring between track 6 of the module's 6-track connector and earth
(connector connected).
Note:
The check procedure is given in the Help section.
Does the voltage vary correctly?
NO
Check the insulation, continuity and absence of interference resistance on the
following connection:
Air conditioning computer 18-track
connector
track 7
Repair if necessary.Power module 6-track connectortrack 6
With the ignition on, check for +12 V accessories feed on track B1 and an earth on track B5
of the black 2 x 5 track intermediate connector (screwed to the base of the console).
Repair if necessary.
NO
YES Contact your
TECHLINE.
AFTER REPAIRPerform a complete check using the diagnostic tool.
