Avalon XLS V6-3.0L (1MZ-FE) (1998)
the electronically controlled transmission solenoid. When shifting to 1st speed. current flows from TERMINAL S1 of the engine control module
to TERMINAL 3 of the electronically controlled transmission solenoid to GROUND, and continuity to the no.1 solenoid causes the shift.
For the 2nd speed, current flows from TERMINAL S1 of the engine control module to TERMINAL 3 of the electronically controlled
transmission solenoid to GROUND, and from TERMINAL S2 of the engine control module to TERMINAL 6 of the electronically controlled
transmission solenoid to GROUND, and continuity to solenoids no.1 and no.2 causes the shift.
For the 3rd speed, there is no continuity to no.1 solenoid, only to no.2. causing the shift.
Shifting into 4th speed (overdrive) takes place when there is no continuity to either no.1 or no.2 solenoid.
2. LOCK-UP OPERATION
When the engine control module judges from each signal that lock-up operation conditions have been met, current flows from TERMINAL SL of
the engine control module to TERMINAL 2 of the electronically controlled transmission solenoid to GROUND, causing continuity to the lock-up
solenoid and causing lock-up operation.
3. STOP LIGHT SW CIRCUIT
If the brake pedal is depressed (stop light SW ON) when driving in lock-up condition, a signal is input to TERMINAL STP of the engine control
module. The engine control module operates and continuity to the lock-up solenoid is cut.
4. OVERDRIVE CIRCUIT
^ Overdrive ON
When the O/D main SW is turned ON (O/D OFF indicator light turns OFF), a signal is input to TERMINAL OD2 of the engine control
module and engine control module operation causes gear shift when the conditions for overdrive are met.
^ Overdrive OFF
When the O/D main SW is turned to OFF (O/D OFF indicator light turns ON) the current flowing through the O/D OFF indicator light flows
through the O/D main SW to GROUND, causing the indicator light to light up. At the same time, a signal is input to TERMINAL OD2 of the
engine control module and engine control module operation prevents shift into overdrive.
5. ELECTRONICALLY CONTROLLED TRANSMISSION PATTERN SELECT SW CIRCUIT
If the electronically controlled transmission pattern select SW is changed from normal to power, the current flowing through the power indicator
light flows to GROUND. Current flows to TERMINAL PWR of the engine control module. The engine control module operates, and shift up
and shift down occur at higher vehicle speeds than when the SW is in NORMAL position.
