Toyota - Prius :: 2005 - Leveling Headlight Malfunction Light On?
Sep 10, 2011
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.

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.

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.

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 '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?

This morning, during a routine drive to work in my 2007 Toyota Prius, my instrument panel lit up with the brake light and ABS light. The car braked normally, although when I tested the anti-lock brakes in a parking lot, the car slid and the ABS did not engage. I brought it to a shop - they ran a diagnostic and came up with a Malfunction of the Hydraulic System - right rear. They said I need to take it to a dealer for repairs. This car has cost me a lot in repairs over the last year...and with 170,000 miles, I'm not willing to put in a lot more.

I just got my IS350 F-sport which equipped with HID headlight for few days, but I have encountered a weird problem as every time I start the car the HID headlight never does a self-leveling job. It just never goes up and down and back to its original spot in which I have never encountered in my previous owned vehicles.

I have a 2013 rx350 rebuilt suv. I had a mechanic check out my Headlight leveling error that comes up. Turns out the motors are missing for my headlights. I called the dealer and they said I have to buy the whole headlight assembly. Are those motors part of the headlight assembly? Can they be bought separate? I found some on ebay but need more information where they are located.

I noticed the light below which seems to be a headlight self leveling error appear today. I know it came on a while back and disappeared butt the place its located is unnoticeable as its in the top corner and you have to tilt your head to see it so not sure if it came on many times.. But yeah I saw it today while waiting for my turn at the car wash since it was nice and sunny out and I leaned over to pull the foot brake release then saw it... It seemed to disappear a few minutes later.. then I stopped somewhere, came back started car and same thing and then it disappeared again. A while later it came on stayed on..
what could it be? I am aware that there maybe a 2 sensors, one in front and other in rear axle? I also know there is a module for left and right side... I am wondering what it could be, but I haven't got the code read yet..

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.

My T-rex was in recently for what seemed like 30 recalls... In the midst of it...my turn signal light bulb went out. They changed it...good thing cause you need to remove the ENTIRE headlight assembly with a special tool, etc. Well...my headlight now goes on/off as it hits bumps etc...was back in once to have it fixed...and has since started again. I noticed the entire assembly does not fit as well (tight) as it did originally, nor like the other assembly that has never been touched. Appears to have been the first assembly they have worked on and broke something cause now it does not mount properly...so after all that...
Had this headlight assembly removed?

I have an 07 Passat Wagon. The headlight malfunction indicator light came on for my passenger side low beam. I replaced the bulb, which was visibly burn out (broken filament), but with a new bulb in, the light still is not working and the malfunction indicator is still on. What is the cause of this? I have the regular headlamps, not the xenon lights.

I pulled my 2005 Prius out of the garage today and parked it on the driveway. When I went back later that day to pull it back under the garage, nothing would work and the "Malfunction Indicator Lamp" came on. I was thinking my battery in my key had gone bad and replaced it. When I tried to start the car for the second time the engine would not turnover, the clock light looked dim, the locks would not work and my headlights would not come on.

A squirrel chewed through some wires in my 2009 Toyota Corolla. My left headlight went dim and my airbag light came on, all within a matter of days. I had the wires repaired and the airbag light never went off. I waited for months until I found out that my airbags won't deploy if I am in an accident. I did some research and from what I gathered until the problem is fixed the light will remain on, (Problem cannot be reset).
I took it to the same guy who fixed the wires .The code that came up was a faulty module. He said since my bags did not deploy the module most likely tripped and he could try to reset it. He tried to do it manually and by the SRS reader with no luck and told me I should go to a shop with a more advanced reader so they could try to reset the module and if that doesn't work go to Toyota.
Can this problem be reset? If it is reset how do I know there still is not a problem that needed to be fixed?

It's one of those days again when the temps are starting to get hot here in Austin, Tx. My AC started acting up during the Spring and first started working fine then after about 10-15 minutes of driving the air starts to blow warmer. The air doesn't go back to cold unless the car has been parked and off for several hours or overnight, and even after that it only blows cold for 10-15 mins again.
Well, I didn't have the time/money to mess with it. The recent May it stopped cooling completely. I recently took it to a local shop and we look at it together. Drained the system and the mechanic was saying it's pulling some air and a little refrigerant. Well, we recharged the system and we could only put in 0.5 lbs and the Low side just maxes out. The system is supposed to hold 1.06 lbs so we were left scratching our heads.
Decided to check for leaks, discharged the system again and hooked up a vacuum pump and see if the gauges will go below 0 for negative pressure and they never did. So the shop doesn't think my system has a leak. They could have used a dye to check but didn't have any on the shelf at that moment.
I also have a DTC code of B1476 and we followed the shop manual. Fans blow into the engine and sometimes we had the bubble but couldn't add more refrigerant due to the Low side being maxed.
My father thinks I most likely have a blockage somewhere in the system. If so, how I can check for this? Is there a specific place or two I can look to find out the system is blocked?
Some people on the form seem to have AC problems, including some with the B1476, and others that couldn't find the problem very well. I'm worried that replacing the compressor wouldn't solve the problem, especially if there is a blockage or something. I usually do a lot of mechanic work but I've never actually worked on an AC system before. I would love to dive into this, even if I can only do part of it and then send it to the Toyota dealer for a flush and charge.

For the last 5 days my passenger headlight has been out so i switched on the brights to other drivers dismay because the brights worked it seemed, shortly after my drive home they went out too. So my drivers side is working fine, turn signals working fine.
(FYI these are not HID Headlights they are base model regular headlights)
Today i spent a painful 20 minutes taking out the bulb and replacing it, showed light wear but didn't seem burned out (i replaced it anyways) PS i made sure not to touch the bulb to my skin as that usually results in a burn out.
The one thing i did notice was the wire connector that goes over the 3 prongs from the bulb itself was a little worn out and had some black around the edges.

I have a 2004 Prius with self-leveling headlights. I have no problems seeing at night but i have a red triangle on the dash and the headlight symbol on the monitor. I was able to aim the lights level when the self-leveling sensor broke. but is there a way to disable the sensor so i don't have any of those symbols on the dash or monitor it just is pain to look at the the sensor cost to much and it doesn't have any affect on driving during the day or night.

My 2005 has an intermittent headlight problem. The drivers side headlight goes out intermittently when it rains.. That is, it does not blink on and off just that sometimes it goes off and sometimes it doesn't. As I live in Phoenix Arizona this does not happen often but it has been happening for a year or so. I go looking at all the connections, where ever they are.

I've got some issues with my 2005 Toyata Prius (~150,000 miles). My wife was driving recently and the "Master Warning Light", the "Hybrid System Warning Light" and the yellow "Brake System Warning Light" all came on.
Some quick reading of the owners manual said we should take it to a dealer right away, but because it was a yellow, and not red, brake system warning light it seems ok to drive at least to a dealer. in regard to the yellow brake system light the manual said it could be that: "the regenerative brake system failed or that the hydraulic brake system failed".
Now, I have a cheap bluetooth OBD reader hooked up to the "torque" app on my phone and I thought I would try to see what error codes there were to learn more. But strangely, it did not read any fault codes. I've used this reader successfully on my 2001 Mitsubishi galant, but I'm not reading anything for the prius in this case. I'm not sure if there is legitimately no error code associate with the warning lights or if my app is just failing to read them for some reason.
