LX 450 L6-4.5L (1FZ-FE) (1996)
operation, such as driving up a hill, the overdrive is released and the power increased to prevent a reduction in the vehicle speed.
^
After releasing the overdrive, vehicle speed becomes higher than the over drive return speed (set speed minus approx. 2 kph, 1.2 mph), the
ECU judges by the signals from potentiometer of the actuator that the upward slope has finished, and overdrive is resumed after approximately
6 seconds.
^
During cruise control driving, the cruise control operation signal is output from the cruise control ECU to the engine control module up on
receiving this signal, so the engine control module changes the shift pattern to normal. To maintain smooth cruise control operation (on a
downward slope etc.), lock-up release of the transmission when the idling point of the throttle position is "ON" is forbidden.
