I had replaced the skid plate module as it was defective with a unit from 2007. The brakes work perfectly but the ABS, VSC ( !) light are on. The codes on the mechanic's computer show non-communication between other modules.
View 3 RepliesWe recently purchased a used 2006 Prius. The vehicle has approximately 74K on it now. Well the other day my wife went to leave work and pressed the power button while pressing the brake pedal, and the Master Warning Light and brake warning light both came on. The car would not allow her to shift the car so she tried to turn it off and it wouldn't do that either. After about 5 minutes she finally got the car to turn off, and when she restarted the sequence everything went back to normal and she drove home fine.
We called 2 dealers and they both seem to be confused by the symptoms, but one thought that maybe the battery was old on the transmitter. So thinking that might make sense I replaced the battery with a new one.
I haven't checked it myself, but a guy told me yesterday that my left brake light is out. I don't see any information in my manual about replacement brake lights.
View 3 RepliesI bought a used 2004 Prius with 121K in June. Noticed recently the passenger side brake light is out. I'm talking about the brake light, with the LEDs, not the rear taillight.
View 2 RepliesMy '07 Prius was running fine until. Pulled into the driveway and shut down then decided to back in some more. Powered ON and ABS and also the BRAKE light came on - car would not shift and the shift indicator & fuel gage started BLINKING. Shut down and repowered with same results.
I've checked the 12 volt supply and it is 12.7, even added a second battery to the engine bay jump start. I used an OBDII reader and get no codes only an E. No improvement .
I have a new-to-me (2 weeks) 2004 Prius, and my wife has noticed a weird behavior on start up which I have not been able to reproduce.
Occasionally when she starts up the car the brake light comes on as if the parking brake were set. The ready light will not be on. No other warning or error lights come on. If she turns off the car, and then turns it on again the light will be off and not return. Tapping or setting and releasing the parking brake has no effect.
She swears it has nothing to do with her pushing the parking brake or not pushing the pedal brake. This seems to have started after I set the parking brake one afternoon, but that could also be coincidental.
My mother owns a 2004 Toyota Prius, we got the car couple of months ago, and noticed the brake light was out, on the drivers side. Little did we know that it was a hard thing to actually replace, and we didn't bother giving much care to it since we thought it was a regular $15 bulb you just pop onto the tail light.
It turns out, the top part of the brake light attached to the remainder of the tail light does not turn on, while the center and passenger side of the brake lights turn on. It is black colored/tinted, and my guess is this is an LED.
I charged the almost dead 12v with a slow charger and it is fine now. but immediately after charging the brake system light came on. I believe brakes are just fine, and want to reset the light and see if it will ever give again.
View 3 RepliesI drive an 05 Prius the drives side LED part of the light is dim. I went to the dealer and they told me I had to buy the hole light assembly. Is this true?

View 14 RepliesI just bought an '07 Prius with all the options except leather, and when I took my wife out to show her how it works, it didn't. The emergency brake light wouldn't go off and the shifter light on the dash would only go to neutral. We turned it off and on again (more than once) and finally the e. brake light went off and the zero showed up for speed and we could go. I'm wondering if there is some safety feature that won't let you engage to go until the e. brake is released. And if the light is on, the car thinks the e. brake is still engaged. Plausible? How do I fix it? Would this be the switch on the pedal?
View 6 RepliesI have a 2005 Toyota Prius with about 150K miles on it. After work one night i hit a pothole and my ABS and BRAKE lights came on. I took it to a garage and they could t find anything wrong with it so they reset the light. It came back on about a week later (no potholdes this time) and i took it back. They hooked it up again this time it said there was an issue with the computer coding. So i took it to a Toyota dealership. They hooked it up to all their scanners and could find nothing wrong with my vehicle. They recalibrated the sensor and the light went off. Now a week later it is back on again. Brakes work fine and we get no error codes.
View 10 RepliesFrom what I've been able to gather there is a proclivity in the 2004-2007 Prii for the emergency brake light switch to break resulting in the dash brake light staying on endlessly. Here is a diagram on page 4 (Powered by Google Docs) of the emergency brake system with the switch labelled and here is a picture of the switch itself (RockAuto Parts Catalog).
I've located my switch and found that one of the plastic side pins is broken off and the whole thing is swiveling around. The problem is that I can't figure out how to get it off so I can replace it with a new one. I don't want to go to the mechanic for something like this.
Also, some of the information I've seen says that I need to replace the entire emergency brake pedal assembly. That could run several hundred dollars and I'm not prepared to do that just so a silly light will go off.
My dealer wants to completely replace the whole tail light assembly because the rear passenger break light is out. Is this really necessary just to replace a light bulb? (2004 Prius)

View 2 RepliesI have a 2006 Prius that I've had since 2012. The parking brake light was intermittently having a hard time turning off every time I disengaged the brake and became more inconsistent until finally, now, for about 6 months the light has just remained on the entire time, regardless of whether or not the brake was engaged.
Just to clarify the brake is still fully functional and will prevent the car from rolling when engaged.
I recently failed my inspection because of the light. The mechanics of the brake are fine, but the light wont turn off. They quoted me around $1,000 to fix due to them having to rip out the whole dash to get to the parking brake assembly (8 hours of labor).
However, is there any way to access the pedal to do the repairs without having to take the interior of the car apart? I've also heard that it could mean my brake fluid is low? But they didn't mention that during the inspection.
Changed my 12 volt today with a yellow top. After starting car found brake warning light on, is the something that will reset when driving?
View 2 RepliesSo I have the dim brake light problem on the passenger side only. I took the whole assembly out to check it out. I removed the circuit board at the bottom and checked all of the components on it with a multimeter. Everything checked out perfectly with the components on the circuit board.
It's just a bunch of resistors connected in series and a diode. All are ok. I put everything back together and the brake LED's are still dim. Of course nothing changed. All of the LED's are lighting up. They are all just dim. The circuit board is being fed with 12 volts.
Today I took my 2006 Toyota Prius with 167,000 miles out to drive my dog to the vet. I turned the car on and deactivated the parking break and noticed the light stayed on, then I noticed the VSC and ABS lights stayed on as well.
My car was parked backwards on a driveway incline for about 14 hours. My 12v battery is old, not sure what shape it is in. The hybrid battery was replaced 2 years ago. I have been reading up and i guess it could be a sensor, skid sensor, 12v battery, or some sort of pump. Also, my parking break has felt a little weak as of late.
The car still drives, not sure if it drives funny or psychologically I think it does.
2005 with 110K miles. Had oil change about 2K miles ago, tires rotated about 1K miles ago. I was at a stop light when I felt a little movement in the brake pedal and the lights all came on. Brakes continued to work, but somewhat harder to push the pedal. When first applying the brakes, there was a very slight wandering of the car, which was easy to correct.
I drove the car home and turned it off. About an hour later I started it and the problem was gone. I took it to an independent garage the next day. Their scan tool found C1357 -- decrease pressure solenoid fault -- but could not go further into sub codes. They recommended that I take it to dealer.
My passenger side brake light has developed a fault over the past couple of months. The brake light will work, for example, when I turn the car on both lights will come on, however if I then take my foot off the brake and re-apply it, it will not work. However later when I am driving I will notice (via reflections) that it is working again!
I am aware that the bulbs cannot be replace and that I would need to replace the whole unit (after market versions available for £75 ish). I have attempted to check the cabling and everything appears OK but I am not an expert. I just removed the rear paneling and made sure nothing was loosely connected.
