Camry XLE Sedan 4-Door L4-2164cc 2.2L DOHC MFI (1997)
For 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 A-1 of the Electronically Controlled Transmission solenoid --> 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
^ O/D Main SW ON
When the O/D Main SW is turned ON (O/D OFF Indicator Light turns OFF), a signal is input into TERMINAL OD2 of the Engine Control
Module and Engine Control Module operation causes gear shift when the conditions for overdrive are met.
^ O/D Main SW OFF
When the O/D Main SW is turned to OFF, the current 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 into TERMINAL OD2 of the Engine Control Module and Engine
Control Module operation prevents shift into overdrive.
