How Came To By The Lx-470

JIM,

On our Land Rovers, all three that we had, the computers are awake so-to-speak. On the 1999 Land Rover Range Rover (air suspension), not the 2003,then 2001 that just died, Land Rover Discovery (coil spring suspension), the computers that controlled the air springs suspension, if the key fob/remote was near the car, ie, the ignition, would wake up and continually adjust the air suspension while we were towing. While running a charge line solved the battery drain, the suspension computer was using up a finite supply of air reserved in the tank making the adjustments. Air was only generated for the suspension when the engine was running to run the compressor. There maybe computers running in the Lexus, so that is why Johnny runs a charge line. But with the key off in the LX, I noticed that the cigarette lighter plug with the phone recharge cord with LED light would not shine if the key is twisted conterclockwise but not removed to keep the steering free., On the Land Rover Discovery, we had to turn the A/C ventilation completely off, turn off the radio, heated seats, etc with the key off, but the cigarette lighter remained on. To prevent battery drain, we place a solar panel with cigarette plug in the lighter to provide Rover's battery with some juice and that eliminated running a charge line for Rover's battery. The Lexus is an unfolding story.
My question to Johnny, "was he using the keyless entry keyfob to keep ther steering unlocked, or was he using the valet key?
