Ok just got a used 05 toyota prius. have all 4 brake lights on the display? tried clearing the break codes and all the brake lights were off for a day,and next day all 4 lights came back? brake fluid is at the max level? ebrake is all the way up? help it's my first prius hybird. need to learn systems on the hybird no experiance with these cars.
The first picture suggests an issue with either the ABS, traction control or VSC. The second one comes on when you applying the e-brake (parking brake) but if it stays on even when you disengage the parking brake, then it's a serious problem as suggested by (a) in the 2nd photo VSC light
Could be. I'm not entirely sure. I'm just throwing out ideas. Hopefully a code scanner can narrow down the issue.
If you have a code scanner, that's convenient, you can get the codes that way and find out why the lights are on. If you don't have such a scanner, or you don't have one yet, you don't have to wait. Here is how you find out why those lights are on: Blink (a/k/a Flash) Codes – How to. | PriusChat
ok got a new xtool d8 this week. scanned for codes and found a few. codes c0205 (did replace both front abs speed sensors) code c1343 code B1421 a/c code B2796 immobiliser code B1821 srs air bag
What does your scantool show for wheel speed sensor data for both front wheels? Driving straight, both front wheels should rotate at the same speeds. C0205 sets when the ecu doesn't like something about the left front sensor - could be a wiring fault, sensor mounting (corrosion), bad toothed ring etc. C1343 sets when the ecu detects a problem with the right rear hydraulic "circuit" - basically anything from (and including) the actuator assembly out to the right rear wheel cylinder. Most common is a leak in the brake system or air in that part of the system after repairs (and improper bleeding). Start with inspecting the brakes for visible problems.

think i found the problem! rear breaks all messed up. the tab that locks the adjusting wheel not locking into place. replaced it with rear brake kit (new drums,brake shoes,harware,new brake tab). cleared brake code with xtool D8 scanner. drove car for 2 days so far and no brake light or abs lights so far.
think my abs brake problem is fixed. cleared the brake codes with xtool D8 scanner. been driving it for a week so far and no break lights. now try fix the security light.
Seems to be a problem with the server (?) Sometimes it works fine when I load a reply, sometimes it seems to do nothing, or "gets stuck" & if I try again, I find duplicate posts later. Posted via the PriusChat mobile app.
