1. DRAIN ENGINE COOLANT FROM RADIATOR
HINT:
It is not necessary to drain out all the coolant.
2. REMOVE ECT SWITCHES
(a) Disconnect the connector.
(b) Remove the ECT switch.
3. 5S±FE engine:
INSPECT ECT SWITCH CONTINUITY
(a) Using an ohmmeter, check that no continuity exists be-
tween the terminals when the coolant temperature is
above 93°C (199°F).
If continuity exists, replace the switch.
(b) Using an ohmmeter, check that continuity exists between
the terminals when the coolant temperature is below
83°C (181°F).
If no continuity exists, replace the switch.
4. 1MZ±FE engine:
INSPECT No. 1 SWITCH CONTINUITY
(a) Using an ohmmeter, check that no continuity exists be-
tween the terminals when the coolant temperature is
above 98°C (208°F).
If continuity exists, replace the switch.
(b) Using an ohmmeter, check that continuity exists between
the terminals when the coolant temperature is below
88°C (190°F).
If no continuity exists, replace the switch.

tween the terminal and switch body when the coolant
temperature is above 93°C (199°F).
If continuity exists, replace the switch.
(b) Using an ohmmeter, check that continuity exists between
the terminals when the coolant temperature is below
83°C (181°F).
If no continuity exists, replace the switch.
6. INSTALL ECT SWITCHES
(a) Install the ECT switch.
HINT:
Lubricate a new O±ring with soapy water and install the switch.

1. FUNCTION OF COMPONENTS
FUNCTIONOPERATION
O/D Direct Clutch (C0)Connects overdrive sun gear and overdrive carrier
O/D Brake (B0)Prevents overdrive sun gear from turning either clockwise or
counterclockwise
O/D One±way Clutch (F0)When transmission is being driven by engine, connects overdrive sun
gear and overdrive carrier.
Front Clutch (C1)Connects input shaft and intermediate shaft
Rear Clutch (C2)Connects input shaft and front and rear planetary sun gears
No.1 Brake (B1)Prevents front and rear planetary sun gears from turning either clockwise
or counterclockwise
No.2 Brake (B2)Prevents outer race of F1 from turning either clockwise or counterclockwise, thus
previnting front and rear planetary sun gears from turning counterclockwise
No.3 Brake (B3)Prevents front planetary carrier from turning either clockwise or counterclockwise
No.1 One±way Clutch (F1)When B2 is operating prevents front and rear planetary sun gears from turning
counterclockwise
No.2 One±way Clutch (F2)Prevents front planetary carrier from turning counterclockwise
