Hi my name is ***** ***** I will be happy to assist with this here today.

If this issue only occured after you went through a car wash there is a chance a brake sensor,solenoid or component had got water into it or shorted out and caused this fault here.

What has to be done from here to locate this issue is to have the fault codes read out with a fully compatible scan tool to see what codes are set.Once this is done any codes set can be diagnosed to locate and repair this issue here.This has to be done with a scan tool that can plug in and communicate with all computers.

One of the more common causes I have seen is a fault with a wheel speed sensor needing replaced.

Let me know if you need anything else and feel free to rate my help here as this is how I receive credit for my time.

Thanks Pete
