Toyota CH-R Service Manual: System Description
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:
- Diagnostic function
- Fail-safe function when a malfunction occurs
FUNCTION OF MAIN COMPONENTS
(a) The main components of the K114 CVT system are as follows:
