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).
