Imobilizer icon blinking after 5k service

It has been blinking when my 2004 is off for the last 2.5 years. Don't worry, its normal.

Mine has always behaved exactly as you describe with the exception of coming on solid when I turn the car off. Mine just starts blinking as soon as I power down and keeps blinking until I power up again. Both of our cars have SKS but you must have the theft deterrent system activated and I do not, thus the 30 second wait for the blinking to start when you power down. That is the time the theft deterrent system is activating. I think everything is working exactly as it should be.

 

<_< 2004 Owner's Manual, pages 6 and 20. This is the "immobilizer/Theft Deterrent" system indicator light. It lights when the key is removed, or with SE/SS when you turn the car off.

May be different page numbers in the '05 '06 Manuals, but the information is found in your Owner's Manual. Although the Owner's Manual is not well indexed, there is a wealth of useful information therein.

 

<_< My best guess.. You just didn't notice it prior to the 5K service. In any event... it is normal.

I might suggest reading it again because you have obviously missed a few things. I suspect you missed the light flashing also because it almost certainly was doing it all along, just as it should.

 

i don't know of anything a tech could do to make that light start or stop flashing, honestly.

 

Too bad it doesn't come with one of those alarms that talks and says, "please stand away from the car" when folks come too close.

Hmmmm, *that* kind of reminds me of older Chryslers; you could get in and ask it, when is a door not a door...? And, if you didn't close the door all the way, it would reply, "[when] a door is ajar..."

c'mon, it's Friday afternoon, for gawdsakes.

yep, normal. unless, someone forgot to uh, plug in the body ecu at the factory... that'll make that light not blink.

however, without body ecu... car no go. so that's out.

immobilizer has to be present for car to operate. immobilizer present means blinking light when car is off. trust us, it's easy to miss, but there's no way there could have been anything missed in vehicle prep or changed at the oil change. don't blame the dealer, like i said they're not even capable of doing anything for that. it just blinks. trust me.

So I just experienced the same thing. After 1800 miles the immobilizer light started blinking when it had not done so previously. Apparently this is the normal function, but like several others, it started up "suddenly". My wife and I have driven for more than a month and not seen this blinking light. I had to look up the manual and then come online to figure out if this was normal (or not).

My daughter who is home from college and does not drive the vehicle noticed this when she got out of our van (and could see inside the Prius). My wife looked and then came and got me. I am certain we would have noticed before this, it is obvious.

Thanks for the fourm and the answers. At least I can sleep tonight.

 

<_< In my new 2007 TE, the 'immobilizer' light blinked from the first day - 4 miles on the clock.

 

I drove to the Toyota dealership today because I noticed the blinking red car with a key for the first time. I've owned my Prius for a year. I can't believe it has been doing it all this time without my noticing. Toyota said it was normal and should always flash. I'm going to ask around to my Prius friend....mostly because the sudden notice of it seems to be a common thread.

 

People by nature are terrible observers.

 

It's funny that I just came across this thread because I had my first oil change recently, and a few days later I noticed this same light blinking in my car for the first time. I'm not saying that the light hasn't been blinking since day one when I got the car, but I just noticed it now. Of course it was at night when I noticed it, and I don't drive the car much after dark, so that's probably why I didn't see it before now.

I also noticed the dealer forgot to reset my maintenance required light after the oil change - but that's easily fixed.

 

I stumbled on this thread for the obvious reasons. I have had my 2009 Prius for 3000 miles now and today I added some washer fluid. This was the first time I had opened the hood. Then low and behold the flashing immobolizer light. My wife and I also swear that it was not flashing previously. Oh well at least it is not a "malfunction".

 

It was flashing, you just didn't notice it. You aren't the first.
