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:

Toyota CH-R Service Manual > Theft Deterrent System: Security Horn Circuit
DESCRIPTION
When the theft deterrent system is switched from the armed state to the alarm
sounding state, the main body ECU (multiplex network body ECU) transmits a signal
to cause the security horn assembly to sound at intervals of 0.4 seconds.
