Gearbox Interface Unit (GIU)

The main function of the GIU is to allow communication between the ECVT and the EMS2000. The GIU has the following functions:

• Conversion of inputs from the selector lever switches (and steering wheel switches if fitted) into a CAN instruction that is read by the EMS2000.
• Drive the LED's to display transmission mode.
• Conversion of the CAN instruction for the EMS2000 into electrical signals to drive the ratio control motor and clutch and secondary pressure solenoids.
