Lexus GX 2004-09 :: 2005 470 - Immobilizer / Security Indicator Light Flashes?
Feb 19, 2013
2005 GX470.After returning home my wife parked the GX470 in the garage. She returned 30 minutes later and noticed the headlights were on. She also noticed the immoblizer light was blinking.
We always keep the headlights in the "auto" position. Headlights staying on is a little strange. but I recall the lights staying on once or twice before. Immoblizer light flashing has never happened.
I inserted the key and turned to start the car and the light went out and the GX started fine. Once I remove the key, the light starts blinking again. I tried this with both keys to make sure it wasn't a transponder issue--all keys did the same as above.
I checked battery voltage--12.4v. Charging--13.6v at idle Some light corrosion around the negative cable but not too bad. cleaned anyway Wife did say she came out of work and noticed that two different car alarms were going off that were right next to her car. Possible kids messing around. Maybe our car was going off as well?

My 2005 prius with 81k on it just had the Hybrid vehicle immobilizer / Theft deterrent system indicator light spontaneously come on during a road trip where she was heavily loaded for the very first time since I have owned her for over 10 years. I stopped at a rest area and when I got back in it was on...immediately my batteries started draining. They are in 50wh mode which has never happened before, and charge will driving, but if I shut down for even a few minutes they are drained again. The dealer told me this was nothing to worry about and that as soon as they fully charged this would stop.

My Prius touring had 4 205/55/16 tires. I had the mechanic change the front two tires to 205/50/16 and now, whenever I drive over 60mph, the slip indicator light flashes continuously. When I slow down, it goes away.
Is it because the front and rear tires are mismatched? If so, I'll have the mechanic change the rear to 205/50/16 as well.

I've read tons of posts about the security system and passlock on the ignition...but my truck does not have a chip key, as the dealer even looked into the key issue with me. There is no chip or resistor on this thing at all.
So, with that said, I have the identical problem as the passlock system people do. The truck will start, then stop, and the security light flashes at me. That's the last thing I want flashing me at 6am when I'm trying to leave for work.
It only happens about once every 2-3 months, but I want to eliminate the problem as I have a feeling one day it's not going to start on me and then the real problems will start...

It appears that the security system is somehow shut down. None of buttons on wireless FOB [main key] is working to open the door etc. even though the red indicator lights up. If I use the key, it opens the doors fine. The powerdoor controls inside the car are working fine. I did notice that security light on the dashboard is not blinking anymore.
The car was idle for three-four weeks and it didn't start so I gave a jump with portable unit. Could that do any damage to fuse etc.?

I am a proud owner of a 2008 gx 470. So far I absolutely love the truck! How to get the "engine immobilizer" light to stop blinking. The other night my battery died. While waiting for a friend to come give me a jump, I noticed the car emblem with a key in it started to blink. After a successful jump, the engine immobilizer is still blinking only when I shut off the car. How I can stop it?

I have a 2006 GX 470, the immobilizer light is flashing but car starts and drives with no problem. How to turn off or reset this light?

I have done 2 searches but came up with nothing regarding a 2010 LS 460L. My security system indicator lights are flashing 24/7 regardless of the car being locked or not. Page 113 is not very clear about how to shut them off. I played with so many buttons yesterday after we got home with the car I may have triggered something without even knowing it. I do not recall that they were doing that yesterday when we picked the car up.

My dad has a 2005 Ford F150 and his airbag light buzzes and flashes. We counted and it flashes 5 times then short pause then 1 flash then long pause and restarts. Also I dont know if it is related but his cruise control doesnt work either.

The cruise control quit working on my 2007 Town and Country. The indicator light in the instrument cluster flashes but won't stay on. If I have the ignition switch on but the engine off the light will come on and stay on.

I have been to the dealer 3 times so far because of something to do with the lighting system. The MFD says "AFS Inoperative" and the indicator light flashes for bulb failure or malfunction in the adaptive front lights system.
The dealer has replaced a bulb and power module thus far, but it hasn't fixed the malfunction. The indicator light and warning comes on 4 out of 5 times I drive the car and usually within the first few minutes of driving. It occurs with our without the lights on.
The lights do work at all times, but I don't think the adaptive steering/lighting is working when the error occurs.

I have a 2006 Jetta TDi wagon. Only when it is cold and first start up of the day, the raditator indicator light comes on and flashes within 1 minutes of start up. I stop the car and restart. It doesn't come back on (unless it is really cold). I have only had it come on 2 times and then it doesn't come on again nor does it come on later in the day.

I just installed a set of HID conversion kit on my 2005 F-150 STX. It is only one beam bulb so therefor I have no high beams. Also, to remind you I have fog lights on the truck. My question is, when I turn my head lights on, and pull the switch to turn on the fog lights, a "blue light" indicator lights up on the dash. It is the high beam indicator and why that is lit. As far as I remember, that light never came on before the install. You have to excuse me since this is my first truck ever and I just got it back after having it repaired at the body shop the last two months. So technically, I only had the truck for 2 months....Just curious whether the blue light is suppose to be on when the fogs are on the dash.

2011 Sonata Se. Keyless fob will not unlock car or open trunk. Brake lights and overhead lights are all that will light. Immobilizer indicator flashes yellow when start button is pushed with brake depressed, car does not even attempt to start.
Putting fob in console will also cause the Immobilizer light to flash, no start up. Holding start button with foot on brake for a minute does nothing.
Owner's manual says call dealer. Car battery is 1 year old and 2 fobs have new batteries, and neither will work.

In my one-owner purchased-new 2005 Prius w/ 74K miles and w/ no maintenance/accident history other than doing all scheduled maintenances at Toyota Dealers along w/ recalls applicable at each time (other than we had Toyota replace the 12V battery last year just because I knew it would die at some point anyway and I don't like pushing my luck; I'm not 100% certain if there's been a recall on any water pump for this car and if so, don't believe the dealer has mentioned it), I have the following indicators which appeared all at once while I was driving along at around 45 MPH in no unusual circumstances (80F, dry afternoon, about 30 minutes into a trip of mixed speeds, no loads in the vehicle, no effect on the car while driving):
From Left to Right on the display:
1) Red Triangle - Master Warning Light
2) Orange (Symbol)CHECK - Malfunction Indicator Lamp
3) Orange (!) - Brake Warning Light (but it didn't highlight the word 'Brake' in red)
4) Orange VSC - Vehicle Stability Control Warning Light
On the Screen:
Orange Car w/ the ! symbol - Hybrid System Warning Light
We immediately aimed for the house (about 5 miles away); the car drove perfectly fine, with the engine stopping and starting at lights as needed, with speeds going from the 55MPH we were traveling at the time of the alarms down to 0 and back up thru 35/45 MPH and such per normal off-interstate driving. The battery currently shows all the blue bars, and the engine and hybrid systems showed charge/discharge as usual as we drove. There was no discernible change in the driving reaction of the car to brake, steering, accelerator, etc.

I bought a new to me 2005. The car came with one fob with the silver logo. The smart key functionality does not work on the car. Lock and unlock works with the fob and I can start and drive with the fob inserted in the slot. Oddly when I push the black button on the outside of the door the red light flashes on the key fob. I have pressed the button under the steering wheel labeled key and that does not seem to change anything. Pressing the button on the door handle causes a long beep to sound.
In addition the light on the dash that is the car with the black key in the middle constantly flashes. It never turns off while driving. I believe this is the same light that acts as the theft deterrent light. I would think that the two are somehow related.

I just bought a 2006 gx that has been lifted about 3" with old man emo springs. The ride height adjustment was removed and the adjustable shocks replaced with a larger non adjustable model.
The rims and tires were also replaced. I think the rims are 21" and the tires 33". The running boards were also removed and the wheel wells opened up a little.
The tire pressure indicator light is on all the time as the new rims and rubber don't link up to the sensor. This I can live with.
I tried it out today on a dirt road (Ophir Pass, Colorado) It worked great but about 200 yards in the check engine, and all three ride/safety system warning lights came on. (stability and slip sensors).
The car performed flawlessly, but the lights remained on even after I got to pavement. I did stop and check, oil, temp, coolant, etc when they came on and all seem to be fine.
I suspect it has something to do with either the oversized tires or the disconnected shock and height systems. How to get the lights to turn off?

My ABS light is on and the 4X4 light flashes about 8 times every few minutes. I thought this would be from a cracked tone ring on teh drive axle, I put the truck up on my floor jack and I did find a cracked tome ring on passenger side. Whoever has the truck used silicone to put the broken tone ring back on. In any event I replaced the drive axle with a new OEM with new tone ring. Drives like a charm but ABS and 4X4 light still on and flashing. It is AWd Is there a tone ring on the drive shaft ?

Today I test drove the car and was told that the key fob was lost and a replacement was programmed for the car to start...but not locks. But while driving it I noted that the Immobilizer / Theft deterrent light was flashing. Is this normal because everything i'm reading says that the car shouldn't even start. I know that the car isn't stolen because we are planning to take over the loan in the morning for the car at the bank. What I should do. If this is because the key was only programmed without the original then can I simply use this one until I can have Toyota make me a new key for around 350-400 based on what I'm seeing online.
Below is the light that i'm referring to (car with key in it).
