Prius (2004-09) :: Parking Brake / VSC And ABS Lights Came On When Powered Up
Jul 11, 2012
I replaced brake pads on my 05 Prius Monday. The instructions I have say to pull 2 relays and pump and hold the brake pedal until I hear a buzz. This has worked fine the last time I did the brakes. This time I got the Brake, Parking brake,VSC and ABS lights when I powered up.
I did not open the hydraulic system, just push in the pistons. I test drove it then touched the brakes. The left front and right rear rotor/drums were hot but the others were not. Long story short, I want to reset the ABS system.

I replaced my rear brake shoes this past weekend. Immediately after I replaced them, the ABS, VSC, ((!)), and Parking Brake lights came on. I had not read that I should've disconnected the 12V battery before changing the shoes, so I wonder if that's related to the issue. I've read through as many threads here that I could dig up, but I still have questions. Here is what I know so far:
Car Info: 2004, 210k miles, Original 12V battery
Relevant Info: While replacing the shoes, one of the seals(?) (rubber part that slid over the piston(?)) slid off. I put it back on, and have checked for any fluids leaking, and have found none. I may pull the rotors off and check this again, though. There were no DTCs logged prior to the shoe replacement. Battery has shown no signs of dying, although I am going to check the voltage on it after I post this.
I tried jumping the pins, and I get the following flash codes (I tried resetting, but they came back immediately):
ABS: 4-2
VSC: 4-5
((!)): 6-5
I tried finding information on these flash codes, but have found nothing...
My CHS Tank was damaged in an accident a few years ago. I just replaced the CHS tank and the Inverter Coolant Pump within the last 12 months. It is still running when I power the car on and off as it should. I also jumped the fuse with a paperclip to double check that it runs.
My brake fluid levels are fine right now.
Possibly unrelated to the lights, but applying the parking brake is very easy. I don't think I adjusted the star adjuster enough. This is my first time messing with drum brakes, so it's possible I didn't adjust that correctly. Are these self-adjusting, or do I need to go back and adjust them by hand?

2002 SC430, 150,950 miles.
Had new front brake pads, re-surfaced rotors, new windshield fluid level sensor installed, 4 x wheels balanced and rotated on 8/11 at Lexus Dealer. Picked it up 8/13, drove 30 miles and it sat 8/14-8/16. Drove to work on 8/17, and on the 18 mile freeway trip home yesterday, the Brake and ABS dash lights came on as I was making a gradual left turn with damp roads.
Thought nothing of it initially, thought my knee had hit the e-brake as mine is very touchy and as long as you pull the release, the light goes away. Not this time. The Brake and ABS lights were on for 4 minutes, then eventually the VSC and VSC OFF dash lights also came on. Steering became difficult, checked brake fluid (ok), checked power steering fluid (ok). No leaks underneath, all fluid levels were just checked on 8/11 and were fine/topped off.
Parked it, set up an appointment and just dropped it off this AM. I've read brake booster, speed sensor, alternator, skid control unit .
I am hoping it's just the alternator, which makes sense with the difficult steering and the lights going on one by one. If the alternator isn't outputting enough volts, those lights will trip. I've had all O2 sensors recently replaced, other standard preventative maintenance done (timing belt, thermo, etc). I'm just hoping it's something manageable and not something that makes me wonder if the repair is worth it (vs the value of the car)...
There are no CEL lights, just the above (no codes to my knowledge).

Just bought a 2005. My wife had turned the car on and had the heater on while I was loading groceries. Then I got in, hit the power button, and the console turned on (though I don't think 'ready' came up), and several of the dash lights came up as amber. ABS, VSC, and 3-4 others. I couldn't shift. After 20 seconds or so of confusion, I turned it back off, sat for a second, and turned it back on again - worked fine.

About two weeks ago I noticed that my parking brake light was not illuminating when I enagaged the brake. Since then it sometimes comes on when I engage the brake but not always (most of the time it doesn't). I can't replicate the conditions and there doesn't appear to be a pattern of temp or time of day.It is an '04 with 146,000 miles.

I see heaps of cheap LED DRLs (audi style) at car accessory shops that say they wire up the the 12volt parking light switch thing, the problem is where this is or how to do it?

Someone told my wife yesterday that her parking lights/tail lights weren't working in her 2004 Prius. When you turn the switch on the stalk one click, only the license plate light comes on. No parking/tail lights come on in the back, and the little lights above the headlights don't come on. Turn the switch another click, and the headlights come on. The brake lights work when you hit the brakes. I checked the fuses: the owner's manual doesn't really match what is in the car, so I checked a lot, and the ones I checked were all fine.
I used up all my diagnosing time deciphering the owner's manual and figuring out the fuses, so I didn't check the bulbs themselves yet (and now it's late, dark, and cold) but it seems really unlikely all 4 of these lights are out at once. Someone else in the forum had a problem where their parking lights only came on when their high beams were on, so I tried that, but that didn't make mine work. There's no history of mysterious electrical problems or collisions. I am able to do some DIY maintenance, and replaced the MFD twice, but have a healthy respect for electricity and don't have any tools beyond a voltage meter.

I 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.

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.

My brother-in-law has an '04 with ~160K miles that we're potentially interested in picking up from him. It's been sitting for awhile with the parking brake on. When going to try it out today I released the parking brake (it seemed to release okay) but both rear wheels were stuck. I drove it a few feet and the left rear freed up but the right rear would not budge (multiple attempts.) It was dragging on their driveway and I could barely get the car back out of the way.
Looking for (videos, manual, etc.) how the parking brake works? Is there an external adjustment I can reach or some place to try to release the cable? We had an '06 that our daughter now drives but I've never had any issues with rear brakes in 200+K miles on that car.

The switch for the parking brake pedal light self loosened (a known issue with this switch) over the past six months and today it finally fell off the pedal assembly. The only way I can see to do the repair is to remove the three fasteners that attach the parking brake pedal assembly to the dash and drop the pedal to the floor to refasten the switch. It appears to be possible; however, there are lots of stuff around the assembly that might get in the way of dropping the assembly so I raised the white flag and called it a day.

I have an 07 Prius that's been going great for me. About two weeks ago I get this strange error message about my P Lock mechanism and how I need to be parked on a flat surface with the parking brake fully engaged. The car wouldn't start, just a bunch of warning lights. Finally I replaced the 12v battery at the dealership.

i have the brake (!) the ABS and the VSC lit up after i got new bearings and new brake pads and rotors, the car was also stalling before the mechanic removed these bearing "dust cover" circles that must have been causing speed sensor interfernce bc the spedometer was stuck on 0....so the car seems to be done stalling after those were removed and all the big lights went off then i hit the brakes a few miles later and those three lights came on...

I recently had a Car alarm/remote start installed in my van and it seems that every now and then my ABS Light and Parking Brake Light come on while driving but if i shut the van off the lights all go out and don't come back on for a few days then it's the same thing. I also changed the front brakes right before i had the install done so i don't know maybe i did something or maybe it was the shop i am thinking it was the shop as they seemed pretty incompetent and could not to this day (3 weeks/19hrs shop time (8hr+3hr+8hrs)) get the alarm to function right.

Suddenly all these lights came on in a 2012 Elantra . Had at the dealer and they checked wheel speed sensors, wiring to sensors and said all those are ok and the abs module is bad. I replaced the module, bled the brakes and the exact same lights are still on with the same codes coming up. Tech is confused as I am.

My son parked the car and I noticed the brake lights were on. After depressing and releasing the pedal a few times the lights go off, then 2 or 3 seconds later, they're back on even when the pedal is released. This happened all of a sudden. I'll pull the switch in the morning and test it, but what else could it be but the switch, right?

I drive a 94 Pontiac sunbird LE, and recently I was driving up to a stop sign and just about stopped when the brake pedal went straight to the floor. I pumped the brakes a few times and they were fine again. Then the next time I started up the car the abs and parking brake lights were on, and stayed on for 4 days. Just the other day the same thing happened again. What is going on?

I have a 2004 Elantra GLS. My left rear brake was hanging (wheel was very hot to the touch after driving, while other wheels were not), so I had a friend check the brake pads. We decided to replace the pads and rotors. While doing so, the parking brake seemed stuck in the on position, so I opted to have him disconnect it completely until I could afford to replace it. I had used it for the first time about 2 weeks before I noticed the hot brake problem, so we figured that must have been why the brake was hanging.
My friend replaced the rotors and pads, put some penetrant/lubricant on the piston of the caliper and reassembled the brakes. He did use the special tool to spin the caliper in when putting the pads on, however he didn't know that was necessary and tried to force them in with a C-clamp first.
Now, I seem to have two problems:
1. The left rear brake still hangs sometimes. I will drive the car and when I park it I can feel the heat coming off of the left rear wheel. It is extremely hot, so I know the brake is hanging (even with the parking brake disconnected). What is the problem here? Is the caliper bad? Would replacing the caliper solve the problem? Does the parking brake have to be connected to stop the caliper from hanging up?
2. My second problem is the pulsating of the brakes. I am afraid the rotor is warped because of the heat, or maybe he didn't clean everything well enough before he put the new rotor on. How can I figure out what the problem is? Is there a way to check a rotor to see if it is warped? Could there be another reason I feel the pulsating brakes? By the way, the brake fluid is full.
If the caliper needs to be replaced and I can leave the parking brake disconnected, are there any special instructions my friend should know about before working on this? He does work on a lot of cars and rebuilds cars to sell, so he is pretty knowledgeable. I think the only thing he didn't know about was rotating the piston. I would like to provide him with detailed instructions if necessary.

Had my car parked outside of work for about 12 hours yesterday, and in the NYC cold front, the parking break must have stuck on slightly. When I started to move, despite the fact I'd released the parking break, I received a warning in the MFI that said PARKING BREAK FAILURE TO RELEASE. I pulled the handle again and heard it pop just a little more off. Everything worked great after that. If I hadn't received the alert I probably would have driven off with it on. I'd probably have noticed the hesitation and checked the break again, but the alert was useful. Some of the warnings in the MFI can appear to be a pain at times, but it's amazing how thorough a job VW has done monitoring the cars systems and giving real time information if something doesn't work. You just have to make sure you don't get info overload from it all!!

So today, I started my Lexus Ls600hl and the lights were flickering and the car wont start. Then on the Dash it has the yellow ! icon and the lcd says Parking brake not available.... The car wont start. I tried disconnecting the battery etc. nothing. Then i jumped the battery and got it to turn on, but it says parking brake not available - see dealer for information. But the car runs fine and everything now - But i don't understand the warning, the parking brake wont engage anymore. I will take it to the dealer tomorrow to see what's wrong.
