COOLING FAN CONTROL
System Description
INFOID:0000000000911871
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).
