SYSTEM DESCRIPTION
SYSTEM DESCRIPTION
(a) The K114 (CVT) is a fully electrohydraulically controlled steel belt type continuously variable transaxle. This is a highly efficient transaxle that is controlled in conjunction with the engine, contributing to enhanced fuel efficiency and quietness without shift shock. In addition, the continuously variable transaxle has the following features:
FUNCTION OF MAIN COMPONENTS
(a) The main components of the K114 CVT system are as follows:
Component |

|
---|---|---|
Continuously Variable Transaxle Assembly |
Shift Solenoid Valve SC |
Used to switch control of the shift solenoid valve SLU between forward and reverse clutch control and lock-up clutch control. |
Shift Solenoid Valve SL |
||
Shift Solenoid Valve SLU |
Performs forward and reverse clutch control or lock-up clutch control depending on the state of the shift solenoid valves SC and SL. |
|
Shift Solenoid Valve SLP |
Controls the oil pressure of the primary pulley. |
|
Shift Solenoid Valve SLS |
Controls the oil pressure of the secondary pulley. |
|
Transmission Revolution Sensor (NIN) |
Detects the primary pulley speed. |
|
Transmission Revolution Sensor (NOUT) |
Detects the secondary pulley speed. |
|
Transmission Revolution Sensor (NT) |
Detects the input turbine speed. |
|
CVT Fluid Temperature Sensor |
Detects the CVT fluid temperature. |
|
Oil Pressure Sensor |
Detects the CVT oil pressure for belt clamping force. |
|
Stop Light Switch Assembly |
Detects the state of the brake pedal. |
|
Park/Neutral Position Switch |
Detects the position of the shift lever. |
|
Shift Lock Control Unit Assembly |
Transmission Control Switch |
|
Combination Meter Assembly |
Shift Position Indicator |
Indicates the shift lever position. |
Malfunction Indicator Lamp (MIL) |
Illuminates or blinks to alert the driver that the ECM has detected a malfunction. |

|
Airbag Sensor Assembly |
Yaw Rate Sensor |
Detects the vehicle's yaw rate. |
Acceleration Sensor |
Detects the vehicle's longitudinal and lateral acceleration and deceleration. |
|
Brake Actuator Assembly |
Skid Control ECU |
|
DLC3 |
Used for connecting the Techstream to read diagnostic trouble codes and ECM data. |
HINT:
The airbag sensor assembly incorporates the yaw rate sensor and acceleration sensor.

DESCRIPTION
The skid control ECU judges brake failure conditions have occurred based on signals
from the brake pedal load sensing switch and master cylinder pressure sensor.
NOTICE:
Do not intentionally stop the engine when driving. Even when no malfunction has
occurred in the brake system, D ...
