security light flash

[skyprince]

I just buy a corllola 2009, ce. I notice that the security light will flash once I turn off the engine and it will flash all the time until I insert key again. The dealer tell me this is immobilizer system functioning. I am wondering if it has to be this way? If I leave my car there for 2-3 months not driving it, it will also flash all the time? I do not see the light flash in dealer's showroom.

If you are not driving the car for months at a time, you should be disconnecting the battery cables and using a trickle charger. Especially during winter months if you live a cold climate.

Yes it will flash all the time and it doesn't take much power so no need to worry. My car will sit for weeks at a time and it hardly drains the battery.

If it's not flashing in the showroom then, chances are the negative cable has been removed for safety and insurance purposes. Perhaps there's another reason since mine is pure speculation.

It's supposed to scare little thieves away.

Don't worry, even after 2-3 months your battery would not have drained enough to cause any problems but to extend the life of your battery it's best to disconnect it and/or have a good trickle charger (not an el cheapo one) connected to it. I say good cause the cheap ones will probably harm your battery more than they help it. In any case, if you disconnect the battery it will kill the radio presets and the clock so beware.

Also as CircuitJerk mentioned, they disconnect the battery in the showroom as they have these cars sitting there for months.

Interesting fact I'll share with you about the presets. I have the Navi package and had my car in storage all winter with the battery disconnected.
When I connected the battery and fired it up for the first time I was surprised to see that all my settings and presets were there. Only thing I had to do was reset the clock.
I'm guessing those settings are stored in flash memory in the unit.

That is very lucky. I installed my HIDs yesterday and i took off the negative for the 20 minute installation and EVERYTHING resetted. luckily toyota doesn't make us input a code for the radio.
