Low level
Check the continuity and insulation from earth of the electrical wiring between tracks A, B and C of the
sensor and tracks 9, 10 and 11 of the air conditioning control unit 30-way connector (sensor supplied with
5 V).
Repair the faulty electrical wiring.
Connect the XR25 and enter # 16. Measure the coolant pressure. The low pressure should be less than or
equal to 2 bars.
Is it correct?
Change the coolant pressure sensor.YES
NOTop up the coolant.
Check that the coolant sensor connector is correctly engaged.
Engage the connector correctly if necessary.

Before carrying out any work, check that the customer uses the air conditioning
correctly.
Non regulated air conditioning.
Check the level of coolant in the cooling
circuit.
NOTE: if the coolant level is too low, the cir-
cuit may become unprimed when driving at
low load and at idle.
Repair if necessary.
Does the fault persist?
Visually check that moving the control
moves the mixing flap.
Does it move?
yes
Check the coolant circuit.
NOTE: fitting an oil, water or air cooler which
has not been approved by the research centre
and which is incorrectly connected may re-
duce or even stop the flow of coolant in the
heater radiator.
Repair the coolant circuit if necessary.
Does the fault persist?
Remove the heater radiator.
Clean or change it if necessary.
Check that the components which were removed are connected correctly.
Check that the system operates correctly.
