Actuators
The Actuator function allows the user to activate certain functions on the vehicle whilst in diagnostic
session. The actuator page can take several seconds to load due to the system reading the current
status of each component and safety feature.
When loaded, the actuator is selected from the list then operated with the control at the bottom of
the data window.
The actuators can be operated in several different ways, depending on the type of component being
operated:
Icon
Description
A single on / off control is represented with a rocker switch
The double switch icon is used for actuators which require two inputs, such as a
duty cycle and frequency. The frequency is defaulted to 100hz and the control is
used to change the duty cycle
Slider is used when a percentage is needed
A telltale icon is used to illuminate and extinguish dashboard tell tales

Sequences are used when there is a requirement to configure, replace or carryout a
pre-defined program within a control unit.
Details for when these individual functions are required will be directed by a customer
support engineer.

Window, follow the preconditions required to carry out the operation.
Reprogramming
Reprogramming is used to update the software contained within a particular
controller.

Software available is listed in the lower part of the Data Window.
Technical Bulletins released at the time of the software release will give full details.

right of the Data Window. Make sure the operator follows the preconditions on the screen (including
connecting the vehicle to a stabilised power supply) and press OK.

reprogrammable and units may have to be returned to McLaren Customer Racing for flashing.
