Hi Josee,

More than likely you have a sensor issue but we need to know what codes you have causing the light to remain on.

Can you pull codes with a scan tool? If not, most parts stores can do that but you will need to find out if they can pull codes from the ABS because not all can. If it doesn't then you may not get any codes.

Once we get the codes we will know what we need to do next. Let me know and we can go from there. Thanks

Okay.

U1110 is Lost vehicle speed message which points to a communication issue between the PCM and ABS.

U11bc is Lost brake switch message

U0001 is a communication issue.

U1120 - is lost wheel distance message

It looks like you are having a failure to have the ABS and PCM communicate.

I would start with trying to find the U1120 code. I attached the testing for this code. You will need to go through the connections between the ABS and PCM on the BUS network. I included the wiring diagram and location of these connectors.

However, before you get to far, you will want to go the inline connector that I circled. It is on the passenger side wheel well close to the PCM. I have seen quite a few of these have water intrusion causing these types of issues. You may have to look close but you will see some of the terminals green with water intrusion. All of these codes go through this connector so I suspect this is your issue. If you find an issue, you can go to a dealer and they can order connectors for you so you don't need to replace the entire harnesses. You just need to tell them you need the connector kits for the I230 connector. The part numbers should be 68080570AA and 68080569AA but just have them double check that to be sure.

Let me know what you find and we can go from there. Thanks
