Range Selection

The PCM receives range selector position by monitoring 3 independent voltage signals from the transmission range (TR) sensor. The TR voltages are then compared to an allowed voltage range for each gear.

Park

With the range selector in PARK:

- The parking pawl locks the output shaft to the case.
- The engine may be started.

- With the key ON, power flows from the high voltage battery through the starter (generator) inside the transaxle, to start the engine.
- The ignition key can be removed.
- The ignition switch can be cycled from OFF to START or RUN.

Reverse

NOTE:Although the engine may be running in reverse, the reverse torque at the wheels is produced entirely by the electric traction motor.
With the range selector in REVERSE:

- The vehicle may be operated in a rearward direction.
- The reversing lamps are illuminated.
- If the vehicle is not started, there is no reverse gear engagement.

Neutral

NOTE:The engine will not start in NEUTRAL; this is a normal condition.
With the range selector in NEUTRAL:

- No power flows through the transaxle.
- The output shaft is disengaged from the drive wheels.

Drive

The range selector DRIVE position provides:

- Low speed driving.
- Acceleration
- Cruise conditions.
- Deceleration
- Maximum fuel economy during normal operation.

If the vehicle is not started, there is no drive gear engagement.

Low

NOTE:There is no increase in acceleration in LOW.
The range selector LOW position provides:

- Engine braking.

If the vehicle is not started, there is no low gear engagement.
If the vehicle is not started, there is no drive gear engagement.

Brake Shift Interlock System

The brake shift interlock system prevents a shift out of PARK unless the brake pedal is pressed. The brake shift interlock system has a brake shift interlock actuator (BSIA) mounted on the selector lever assembly. If the ignition switch is in the RUN position, the BSIA will allow the selector lever to be moved out of PARK only when the brake pedal is pressed.

External Controls

The external control of the electronically controlled continuously variable transaxle (eCVT) is mechanically controlled by a cable connected to the selector lever and electronically controlled by the TR sensor (located in the floor shifter assembly). The selector lever position determines PARK, REVERSE, NEUTRAL, DRIVE and LOW modes.
