Boolean
Description: True
The TCU will follow torque, speed and gear instructions from the VCU.
False
The TCU will remain in Neutral and will disable the MCU.
Note: The TCU will treat this condition as False if it does not have CAN communication with the
MCU.

Description: VCU to TCU Directed Mode of operation.
0: Neutral
Transmission is decoupled from the drive train and the motor is disabled
1: Reverse
The transmission does not have an explicit reverse gear. Reverse is achieved by placing the
transmission in Low gear and driving the motor in the reverse direction.
2: Forward Automatic
The TCU controls whether the transmission is in high or low (most common mode of operation).
3: Forward Low
The transmission is held in Low gear.
Note 1: The TCU will behave as if this field is Neutral if it does not have CAN communication with
the MCU.
Note 2: The TCU should be the Neutral state when voltage is not being supplied to the MCU. The
TCU should not exit the Neutral state until the power-up sequence is completed and the
TCU is reporting MCU status to the VCU.
Note 2: Transition to and from Reverse should only be allowed at extremely slow vehicle speeds
(transmission output speed <50 rpm).
