COOLING FAN CONTROL
System DescriptionINFOID:0000000001162544
The cooling fan motor is controlled by the ECM.
COOLING FAN OPERATION WITH THE ENGINE RUNNING
Cooling fan operate is guaranteed by a 2-speed fan assembly (LOW speed and HIGH speed).The ECM
requests the IPDM E/R to actuate them via the can communication. To provide cooling:
 Engine running
- LOW speed is actuated when the engine coolant temperature exceeds 96 °C (205°F) and is deactivated
when it drops below 94 °C (201°F).
- HIGH speed is actuated when the engine coolant temperature exceeds 104 °C (219°F) and is deactivated
when it drops below 102 °C (216°F).
 If the engine coolant temperature exceeds the threshold of 115°C (239°F), the ECM requests the IPDM E/R,
via the CAN communication, to switch off the air conditioning compressor so as to reduce the load on the
engine and attempt to limit the rise in temperature. The cut-off request is cancelled if the engine coolant tem-
perature drops below 110°C (230°F).
 If a malfunction in the engine coolant temperature sensor circuit is detected, the ECM requests that HIGH
speed operation.
 In addition to engine management, the ECM centralises the cooling requirements for the climate control and
automatic transmission/sequential gearbox functions (where fitted).

ON BOARD DIAGNOSTIC (OBD) SYSTEM
ON BOARD DIAGNOSTIC (OBD) SYSTEM
Diagnosis DescriptionINFOID:0000000001162547
The ECM controls the display on the instrument panel of certain information relating to the operation of the
engine.
Four functions are involved here: The OBD malfunction indicator [MI (Yellow)] for the EOBD (European On
Board Diagnostics), the pre/post heating, the engine coolant temperature and engine malfunction [MI (Red)].
These four functions are represented by four lights given out by the ECM
GLOW LAMP
This lamp indicates that the glow control system has been activated.
ENGINE COOLANT TEMPERATURE LIGHT
This light is used as an indicator of engine overheating.
 In the event of overheating, it is up to the driver whether to stop the vehicle or not.
MALFUNCTION INDICATOR
The OBD malfunction indicator [MI (Yellow)] is used to alert the driver to the existence of engine control sys-
tem malfunctions involving excessive pollution or if the EOBD system is deactivated.
The ECM makes a request for lighting of the MI (Yellow) only where there is a malfunction present at the end
of three consecutive cycles.
The 3-second visual check upon powering up (automatic test procedure controlled by the IPDM E/R) is per-
formed by the ECM.
In the event of a confirmed OBD malfunction by lighting of the MI, no flashing of the light must be observed fol-
lowing the lighting test.
DTCs Causing MI to Light
ENGINE WARNING LIGHT
In the event of an engine malfunction, the ECM may request the display of an engine warning light [MI (Red)].
HOW TO ERASE DTC, 1ST TRIP DTC AND 2ND TRIP DTC
With CONSULT-III
The emission related diagnostic information in the ECM can be erased by selecting “ALL ERASE” in the
“Description” of “FINAL CHECK” mode with CONSULT-III.
MI OPERATION CHART
Some malfunction must switch on MI to warn driver, that his engine emissions exceed OBD thresholds (Euro 3
x 2.5).
The rule is to switch on MI after 3 consecutive driving cycles (engine start + engine stop + power latch) with a
present OBD malfunction.
To switch off the MI (without CONSULT-III), vehicle has to drive 3 consecutive cycles without present OBD
malfunction.
Ignition switch OFF → ON transition, MI remains switched on in pre-drive check mode until engine start.If MI
does not switch off whereas engine is running, there is at least one present OBD malfunction.

DTC DETECTION LOGIC
NOTE:
Conditions for applying the diagnostic procedure to the stored DTCs:
The DTC becomes present during the first 30 seconds after the engine starts.
 In low ambient temperature conditions, diagnostic can.t make difference between a normal long engine start
and abnormal long engine start. So, DTC must be take in account only if customer complains about too long
or impossible engine start not only in cold conditions but also and especially in warm conditions. If customer
complains only in cold conditions, root cause of the problem could elsewhere like low battery level, bad fuel
specification (too viscous fuel). This DTC could appear after fuel filter too.
Special notes:
Starting and engine operation difficult or impossible.
