Starter Lock-out Contact Switch

Function

The starter lock-out contact is installed beside oil temperature sensor and is actuated by a cam rail, which is located on
the latching plate.

In the selector lever positions “P” and “N”, the permanent magnet is moved away from the reed contact. This opens the
reed contact and the transmission control module receives an electrical signal. The transmission control module acti-
vates the starter lock-out relay module. This closes the electrical circuit to the starter in selector lever positions “P” and
“N” via the starter lock-out relay module. In other words, when the selector lever is in driving positions, the contact is
closed and the starter cannot be operated.

Kick-down Control

Function

When the throttle valve is partially opened, the shifting point gets faster. When the throttle valve is widely opened,
shifting point is delayed because the system needs low speed gear with bigger driving force.

Kick-down control is a system that enables to get bigger driving force as the down shift occurs by suddenly increasing
the throttle openings during constant driving. It has no separate kick-down switch where the down shift operates when
a certain point (about 1 second) lapses after opening of full throttle. The signal recognition allows to send control signal
to TCU from engine ECU via CAN communication.

Mode Switch

Function

The mode switch is installed beside the selector lever and it has two modes of “S” mode (Standard
Mode) and “W” mode (Winter Mode).

- “S” mode is used in normal driving (starts off with 1st gear). TCU (Transmission Control Unit)

provides pleasant driving by changing the shifting pattern according to the driving habits
(downhill gripping: approx. 11 ~ 13.5 %)

- When “W” mode is selected, the Winter mode indicator in meter cluster comes on, and the

vehicle starts off with 2nd gear to achieve smooth starting on the icy or slippery road.

In winter mode, the up shift becomes faster and the down shift becomes slower for improving fuel consumption. The “W”
mode is automatically changed to “S” mode in full throttle or kick-down operation. The vehicle can starts off with 2nd
reverse gear (gear ratio: 1.92 ~ 1.93) when the “W” mode is selected. It is very useful on icy and slippery road. However,
in this case, the “W” switch should be selected before placing the selector lever to “R” position.

Even though “W” mode is selected, the vehicle starts off with 1st gear in following:

When the system recognizes the mode switch operation, the selector lever control unit sends the control signal TCU via
CAN communication.

1. When the selector lever is in “1” position.

2. When fully depressing the accelerator pedal or when starting off with kick-down condition.

Reverse/Parking (R/P) Lock System

Function

Reverse (R) lock system is a safety system that prevents the selector lever from shifting to “P” or “R” position by
activating the solenoid valve when the selector lever unit determines that the vehicle speed exceeds 10 km/h by check-
ing the speed signal from wheel speed sensor via CAN communication.

Parking (P) lock system uses the signals from brake switch other than conventional cable system to shift to other
positions. The wiring harness for detecting brake switch operation is connected to selector lever control unit.
