abs light on all the time

pulled code 4 9

Please someone tell me

1: what the book says this is

2: anyone who has fixed this code before if there was an easier or different solution (such as cleaning a sensor instead of replacing.)



Thanks!

 

Check and see if your brake lights work , the code is for the brake light circuit possible brake light switch.

 

From Techinfo.toyota.com

Code 49: Open circuit in stoplight switch circuit

Trouble area: Stoplight switch, Stoplight switch circuit

 

Hey thanks guys Ill test the switch. I very sure my brake lights work, but I know most brake pedal switches are double pole so maybe the secondary switching for the ABS coomputer is bad.


How do I reset this code so I can test any repairs????

 

Disconnect the battery cables ro reset...

 

I left both battery cables off for over an hour, The light is still there, even when I first start the car before pressing the brake or anything.

Someone please explain exactly how to reset the abs light.

My brake lights work fine.

I took the brake switch off the pedal and tested with a multimeter... everything seems like it worked fine.

In my past experience, when you have a code like "Open circuit in stoplight switch circuit" there are usually one or maybe two very common points of failure. Anyone with experience repairing this excact code.

Thanks.

 

Anyone know how to get rid of this. My abs is not working properly all lights are good but abs is no hood
