Prius (2004-09) :: Icon For Automatic Headlight Leveling System Showing On Info Screen
Feb 8, 2012
My '05 Prius with just 16k miles on it just started displaying the red triangle with exclamation mark (multifunction warning lamp?). It displays about every 3 times I start the car... The Info screen shows the icon for the Automatic Headlight Leveling System. So Ive been searching, and have found a few threads related to this, but the fix Ive seen referenced I cannot find since the posts referencing the fix are about 5 yrs old. Exactly where on the car I can find the sensor, and how it can be fixed?

First a bit of history: About a year ago, I received the headlight leveling system warnings comprising a red triangle alert with exclamation point in the middle located on the dash, combined with a yellow(ish) warning symbol on the center stack display comprising what looks like a headlight with up and down pointing arrows. Eventually, the warning lights went out, but the HID headlamps were left pointing in a down position that lit barely 10 ft in front of the car.. This is is supposedly their default position when the sensor breaks, most commonly due to moisture entering the sensor innards resulting in corrosion of the contact points. I effected the repair quoted elsewhere on this forum, and it was good to go.

Just took delivery of my 2005 SC430 (Egyptian Sand, white leather, 55k miles. Lovely vehicle.) which I thought came with Bluetooth.
However, when looking to pair my iPhone 4S the 'Phone' icon is not present on the ML Nav Info display screen, suggesting that maybe Bluetooth is missing? I confirmed it's a 2005 from the VIN.
When I depress the little button below and behind the steering wheel volume buttons (left side - this is a US car) I get a voice saying 'No cassette inserted' or words to that effect, suggesting it's a cassette control button, not a Bluetooth one. The Nav instruction book which came with the car specifically refers to the presence of Bluetooth.
How to find if I have Bluetooth or not? My iPhone cannot 'discover' anything.

I have a problem with our oldest Prius, a 2005 Package V. I have had an ongoing problem with the warning triangle and the headlight icon coming on and off for a few years now. Anyway, after locating the post about repairing the sensor, I finally got around to checking out the headlight height control sensor and when I opened it up, I found it to be badly corroded/ unrepairable. My local dealer wants $500+ to repair the system and I really don't need the leveling function anyway.
My headlight level has been stuck it the same position for a long time, but as luck would have it,. they are at a perfect level....Always pass State inspection, illuminate the road perfectly etc.
The problem that I now have is that the two warning icons stay lit all of the time. Is it possible to disconnect or jump wire the Headlight Level Control ECU or something else in the wiring system to disable/turn-off these two warning lights? I disconnected the corroded Height Control Sensor, but the warning lights stay lit.

2008 Prius with Nav/GPS system and 6-CD audio system. Around 30K miles, Bluetooth failed, and the Telephone Icon no longer appears on the Info Menu. Service Menu shows no version number for Bluetooth software, suggesting it somehow was deleted. Two local Toyota dealers don't know how to fix it. Toyota Customer Service gave wrong instructions: to eject the map data DVD and then reinsert it to reboot the system. That did not correct the problem because the map data DVD has only map data, not Bluetooth. Is there an internal hard drive on the center console unit that holds the software for Climate, Audio, Display, GPS, and Bluetooth? There must be. I need instructions on how to (a) reload the software, or (b) reboot the system to get software to reload. One local dealer said I had to replace the entire unit. That's like buying a new laptop because someone deleted Skype.

I just got the warning symbol that mine has failed, so I'm thinking of trying the repair myself, too. But I thought I'd ask here: how have people's repairs held up? Have you had to go back and eventually replace it? Is there anything you wish you had done differently when you repaired it?
On a related note, I see that the Toyota Service Bulletin for this problem instructs the mechanic to "Perform the Headlight Leveling ECU Initialization procedure using the SST" and then to "Perform the Headlight Aim Only procedure." This doesn't seem like something an individual can do without specialized equipment / knowledge. Is there a way to do it? Is it unnecessary?

My 2005 Prius with around 60K has the occasional Headlight Leveling Warning Light. My question is how serious is this? Do I need to go to the dealer or can I wait on it? The lights still work fine.

My car Gen.2 was 200K. I change the water pump and thermostat on 150K. The reason to change the parts because I think my car a lot of miles. The car run great no problems. Till last month my car had overheat on freeway at night time. The temperature up to 245 F have the red triangle on dash and thermometer icon on Navigation screen. Before overheat on same day on the daytime when I take off I heard sound water running in the engine. The day after I check the level coolant in the reservoir tank was full but in the radiator need to fill up the coolant. After that when I drove the car the coolant overflow form the reservoir all the time. I have to check and fill up the coolant in the radiator every morning. I been the many shop ask them about the symptom of my car. Some they told me water pump failure, some said thermostat failure open all the time or some told me head gasket leak. I check all the engine didn't see any leak but I saw coolant overflow from reservoir...

Vehicle: 2009 Toyota Prius Base ... Recently my car started showing the master warning light along with the temp warning light on the navigation screen. After opening the hood and inspecting, there is a coolant leaking from somewhere. Took it to the dealer and was told there is no leak but a bad/blocked coolant tank assembly. Question is, if I bought the tank myself for under $1k, could I replace it myself? What would be involved besides replacing coolant? Do I need to get the air out of the lines? Etc.

I have been having some hybrid battery issues. My prius is a 2006 with 198,000 miles. The original battery was replaced at around 120,000 with a junkyard battery. About a year later that battery gave up the ghost and I decided to rebuild that battery. So far that has worked quite well until recently.
My troubles started a couple weeks ago when I got the Red triangle and all the dash lights and the hybrid system icon on the MFD. Naturally I thought it was the battery again. Took it out and checked the voltages of the modules. All the modules where within tolerances. I grabbed a OBDII scanner and checked the code. It was telling me that the Hybrid current sensor was bad. I changed that out with the wiring harness from the old battery.
That lasted for a few days before the red triangle came back. I checked the code and it was indicating one of the blocks was bad. I think P3019. So I took the battery back out and replaced that block with other modules. Almost instantaneously the red triangle came back with two more bad blocks. I think it was P3012 and P3022. So I took the battery out once more and tested all the voltages of all the modules. Everything was 7.86-7.9v. So I decided to start the rebalance of the existing modules in hopes to find some bad modules.
I also bought a new 12v battery and installed that. I got everything back together and took it for a road test. It took about 30 mins before the triangle came back. I grabbed the codes and it was still indicating bad blocks. P3011 and P3018. I am a little at a loss.

Does the cruising range in the drive information screen NOT reset unless you fill the gas tank ALL the way up?
I just threw in a few bucks (well it's a Prius after all) and it still showed 0 as the range.

The Navigation touch screen does not work. I can still us controls on the steering wheel, bu the touch screen is dead. I am assuming that I just buy and install a new screen? Or could there be something else to trouble shoot?

The dealership states that this is not a big problem and that the headlights will not be affected but the malfunction light stays on and the exclamation point is on the dashboard. The fix: replace the rear sensor harness where corrosion on the connection and pin was found - new harness assembly needed. What about just replacing the pin? Dealer states you cannot cut the wire and replace because the wires are not sealed.

Wife said the info screen quit for a block this morning. The radio also stopped at the same time. After a block it came back to normal. Is this a sign of something coming? We have a 2005 genII with 80,000 on it.

Just got a new 2012 Prius II today. Got in the car with my iPod "splitter" cable adapter (on one end it has the ipod connector and on the other end is the USB & Auxillary cables), my 6th gen ipod nano, and hooked it up only to find that the Audio info was not connecting to the screen. I found that you do not need this "splitter" cable, all you need is your ipod adapter. You can use the that auxillary cable for a Walkman or something ! Glad, I figured it out the first day or i'd be pissed trying.

2007 Gen II Prius, at 135K.
Over the last couple days, the console beeps (same beep as the low fuel one) and the word 'Problem' flashes at the top of the screen. It goes away, then nothing happens. The vehicle is otherwise running fine, no symptoms. The 'Maintenance Required' sign is on on my dashboard, but that's been on for a while now (a month) for a routine oil change (so I think that's the only reason it's on).
