Sienna LE V6-3.0L (1MZ-FE) (1998)
solenoid performs the 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 out.
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.
