Value until the road speed displayed on the Engine Data Page and the actual vehicle speed
agree.
Go to the Options page in the software, and select the Torque Converter Lockup function on
the appropriate output. The map for the TCC function indexes the vehicle road speed against
the throttle position. When, for any given throttle position, the road speed is greater than that
displayed in the map, the solenoid will be energised. The road speed must then fall 8 kph
(5mph) for the clutch to be disengaged. This 8 kph hysteresis should prevent solenoid
oscillation during cruising near the cut-off point. The default map activates the solenoid at 70
kph at smallest throttle opening, and increases the activation threshold to 160kph at 70%
throttle. Although this map may be customised as required, it is advisable to never engage the
lockup below 60 kph (40 mph).
Note: When using the TCC function, the Aux. In Function in the
Identification must be set for Torque Converter Control. When using TCC,
other functions that use the Aux. Input line cannot be used.
16.6 Electric Thermatic Fan Control (TF)
This function can be used to switch on a thermofan when the engine temperature exceeds a
certain value. The fan will stay on until the engine temperature drops below a second value.
Note: The electric fan cannot be driven directly by the ECU. A relay must be
used to switch the high currents drawn by the fan.
To use this function, you must have the following:
An electric thermofan, fused and relay switched;
E6H/E6M programming software and cable.
Install the wiring for the thermofan to one of the Digital outputs as described in figure 16.6.
Be sure that the relay contacts are rated higher than the current drawn by the thermofan.
Run the E6H/E6M programming software and go to the Options page. Select the Thermofan
function on the appropriate output and set the two temperatures as required.
Switch On Temperature
The temperature the engine coolant must exceed to switch the fan on.
Switch Off Temperature
The temperature the engine coolant must drop below before the fan will be switched
off. This parameter should be at least 5° lower than the Switch On temperature to
prevent the fan from switching in and out quickly.
