CVT FLUID COOLER SCHEMATIC
COMPONENT DESCRIPTION
CVT Oil Warmer
• The CVT oil warmer (1) is installed on the front part of transaxle
assembly.
• When engine is started while engine and CVT are cold, engine coolant temperature rises more quickly than CVT fluid tempera-
ture. CVT oil warmer is provided with two circuits for CVT and
engine coolant respectively so that warmed engine coolant warms
CVT quickly. This helps shorten CVT warming up time, improving
fuel economy.
• A cooling effect is obtained when CVT fluid temperature is high.
Heater Thermostat
• The heater thermostat (1) is insta lled on the front part of transaxle
assembly.
• The heater thermostat open and close with set temperature.
SHIFT LOCK SYSTEM
SHIFT LOCK SYSTEM : System DescriptionINFOID:0000000009463986
The shift lever cannot be shifted from the “P” positi on unless the brake pedal is depressed while the ignition
switch is set to ON. The shift lock is unlocked by turn ing the shift lock solenoid ON when the ignition switch is
set to ON, the park position switch is turned ON (selec tor lever is in “P” position), and the stop lamp switch is
turned ON (brake pedal is depressed) as shown in the oper ation chart in the figure. Therefore, the shift lock
solenoid receives no ON signal and the shift lock remains locked if all of the above conditions are not fulfilled.
However, selector operation is allowed if the shift lock release button is pressed.

TCM
Fail-safe
INFOID:0000000009464002
TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically contro lled input/output parts is damaged.
If the vehicle shows following behaviors including “poor acceleration”, a malfunction of the applicable system
is detected by TCM and the vehicle may be in a fail-sa fe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.
