Air conditioning function
The SIM32 computer manages a "Cold Loop" type air conditioning system:
–request for air conditioning by logical link,
–acquisition of pressure in the air conditioning circuit,
–vehicle speed
–air conditioning compressor control,
–fan unit control for the requirements of this function.
The injection computer reconstitutes the power absorbed by the air conditioning compressor and fast idle speed
requests by using the pressure acquired in the air conditioning circuit.
These signals are necessary for adapting the engine management (idling speed regulation, air flow correction, etc.),
for several reasons:
–air conditioning compressor efficiency,
–more engine ruggedness due to torque hesitation caused by the compressor clutching and declutching,
–helping the alternator.
Fan unit 1 and/or 2 requests are reconstituted according to the pressure in the air conditioning circuit and the vehicle
speed. In summary, there are more fan unit requests when the speed is low and the pressure is high.
OCS - Customised Oil Change Interval (does not concern Vdiag 44 and 4C).
This program takes into account the driving style of the user to warn him of the need for an oil service. It counts the
number of revs per minute since the last oil service, corrected by a factor dependent on the oil temperature. When
this number of revs per minute exceeds a certain threshold, the customer is alerted by a message on the instrument
panel informing him that an oil service is required.
After the oil service, the user must reset the oil service interval on the instrument panel.
To find out if the engine concerned uses this programming, consult ET840 Customised Oil Change Interval.
OBD
The OBD programs are as follows:
–catalytic converter fault finding,
–upstream sensor operational fault finding,
–misfire fault finding,
–fuel supply system fault finding.
The misfiring and fuel supply system fault finding is performed continuously. The operational fault finding for the
upstream sensor and the catalytic converter can be only be carried out once per journey, and can never take place
at the same time.

If the fault is still present, carry out the following checks:
The inlet line must be perfectly sealed, from the throttle valve to the cylinder head.
Check:
–the condition of the air filter,
–that the air inlet circuit is not blocked,
–the sealing between the throttle valve and inlet manifold,
–the manifold pressure sensor sealing,
–the fuel vapour absorber bleed, which must not be jammed open,
–the fuel vapour absorber bleed system sealing,
–the brake servo system sealing,
–the cylinder head oil vapour recovery system sealing,
–the sealing between the inlet manifold and cylinder head,
–the exhaust pipe sealing between the cylinder head and catalytic converter.
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair:
- If the fault is present, continue to deal with the fault.
- If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.
