Neutral Start Function
The power train ECM will not allow the engine to be started unless the direction control switch is in the NEUTRAL position. The operator controls this feature by placing the direction switch in the neutral position. The operator can then turn the key start switch to the START position. After the conditions are met, the ECM activates the start relay which allows the starting motor to turn. STIC Steering and Transmission Control
Illustration 1 g01124598
STIC Steering and Transmission Control (1) STIC Upshift Switch. (2) STIC Downshift Switch. (3) STIC Steering and Transmission Lock Control. (4) STIC Transmission Direction Control Switch. The VIMS refers to the STIC steering and transmission lock control as "STRG/TRN LCK".The STIC steering and transmission control is positioned at the end of the left armrest. The transmission direction control switch (4) is a three-position switch that selects either neutral, forward, or reverse. The upshift switch (1) makes momentary contact in order to select the next higher speed. The downshift switch (2) makes momentary contact in order to select the next lower speed.STIC Steering and Transmission Lock Control
When the STIC steering and transmission lock control (3) is moved to the LOCKED position, steering is disabled and a switch is depressed. The input from the switch causes the power train ECM to shift the transmission into neutral.When the STIC steering and transmission lock control is moved to the UNLOCK position, the operator has control of the steering and the transmission. The power train ECM will not shift the transmission into a speed until the direction control switch is first moved into the NEUTRAL position.Transmission Lockout Switch

Left side of the machine in the rear bumperA remote transmission lockout switch is located in the bumper on the left side of the machine. When the transmission lockout switch (6) is in the LOCKED position, the input from the switch causes the power train ECM to shift the transmission into neutral and the transmission lockout indicator (5) is turned on.Note: When the transmission lockout switch is in the LOCKED position, steering remains enabled.When the transmission lockout switch is moved to the UNLOCK position, the operator has control of the transmission. The power train ECM will not shift the transmission into a speed until the direction control switch is first moved into the NEUTRAL position.Parking Brake Function
When the parking brake is disengaged, the transmission will shift normally. When the parking brake is engaged, the transmission will not shift out of neutral to first speed forward or first speed reverse. If the transmission is in first speed forward or in first speed reverse and the parking brake is moved to the engaged position, the transmission will shift into neutral. If the transmission is in second speed forward or in third speed forward, the transmission will remain engaged.When the power train ECM shifts the transmission to neutral, the power train ECM will not shift the transmission into a speed until the transmission direction control switch is moved to the NEUTRAL position and returned
