NOTESConditions for applying the fault finding procedure to stored faults
The fault is considered present when the engine is running.
Special notes:
The heating and air conditioning system request is not longer possible.
The compressor is still active, risk of irreparable damage to the compressor (loss of
capacity). The customer is complaining that the air conditioning is operating
continuously.
See Technical Note Wiring Diagrams of the vehicle concerned
Check the connection and condition of the injection computer connector, component code 120.
Check the connection and condition of the air conditioning compressor relay connector, component code 5845.
If the connector(s) is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Run command AC180 Air conditioning compressor relay control.
If the command does not work, check, with the ignition on, for +12 V on connection 3FB of component 584 and
for earth on connection 38K of component 584.
Check the insulation and continuity of the following connections:
–38K between components 584 and 120,
–3FB between components 584 and 238.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fault is still present, run fault finding on the climate control computer (see 62B, Climate control).
If the fault is still present, check the relay and replace it if necessary.
If the fault is still present, contact the Techline.

or does it separate into 2 parts?)
Check the connections of the water in diesel fuel sensor, component code 414.
Check the connections of the engine management computer grey connector, component code 120.
If the connector(s) are faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
With the ignition on, check for +12 V on connections 3FB1 or 3FB2 (for New Twingo) or AP15 (for Kangoo 2) of
component 414.
Check for earth on connections M or 3WU (only for New Twingo) of component 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
