3) Shift Map Selection
The driver can manually select between normal (S) and winter modes (W) via the mode switch.
Depending on the transaxle temperature, uphill and downhill grades and altitude, shift maps will be
selected by the TCU to suit the driving conditions. The following maps are available.
Standard (Normal) Mode
▶
Normal Mode is selected when the lever is in the D position with the mode switch in the normal (S)
position and the transaxle is within normal temperature ranges. Shift schedule points are optimised for
fuel efficiency and general driving conditions.
Uphill and Downhill Mode
▶
In this mode, depending on the load of the vehicle, adaptive shift maps are selected to progressively
adjust the shift points and torque converter lock points.
Altitude Mode
▶
Shift points are automatically adjusted at higher altitudes to compensate for changes in engine torque
where the torque produced by the engine is greatly reduced by the effects of reduced barometric
pressure and temperature.
Winter (W) Mode
▶
When winter mode is selected, starting in second gear is facilitated and the WINTER mode indicator
light is switched ON. To prevent wheel spin on slippery surfaces, the transmission will not allow first gear
unless manually overridden.
Warm up Schedule
▶
Used typically when transaxle fluid temperature is below 20°C.
The torque converter will not lock-up below 20°C to assist in transaxle warm-up.
Hot Mode
▶
The hot mode is progressively applied between temperatures of 110° ~ 200°C. The torque
converter lock-up is increased to prevent heat generation by the torque converter.
Activation of the hot mode inhibits other transmission performance features including uphill and downhill
compensation and altitude compensation. Some degradation in shift feel may be experienced as the
torque converter is not unlocked during shifting.
Cruise Control Mode
▶
When cruise control is activated the engine ECU may request the transaxle to downshift under trailing
throttle conditions to increase engine braking.
Above 110℃
the electrical radiator fans are switch ON
Above 130℃
the engine torque will be reduced and the W light on the instrument cluster will flash
Above 200℃
the transaxle will neutralise until the fluid temperature falls below 200°C as a final
protection.

6. CAN NETWORK
The TCU sends signals to be used by other vehicle systems via the CAN bus, such as:
Selector lever position
Selected gear state
Manual mode activation
Output torque
Transaxle fluid temperature
Engine torque reduction requests
