Hello and welcome to ExpertHelp.com! My name is Charles Totherow and I'm going to do everything in my power to answer your question to your full satisfaction!

Before we get started, I want to remind you ExpertHelp.com is an independent professional support company. We are not associated with nor are we paid to provide support on their behalf. However, we have helped hundreds of customers with similar questions and believe we can help you too. OK, let’s get started! :)

I might need to request additional information from you to better understand how to help you. Please read my replies and respond to them as soon as you can so we can have this solved in no time. Hang tight while I prepare my next message.

Could also be loose or dirty battery connections. Inspect connections. If they have no more adjustment left I would replace them. Also check your negative battery connections on the frame and motor. A loose or dirty frame or motor ground can cause all sorts of weird issues. They will also make your alternator test lower than normal voltages.

Also, . If you look on the inside of your front tires there is a plug that has two wires it looks like it goes to the brakes

This light will come on when the computer sees a problem that affects the performance of the engine or transmission. There are many problems that can fail that will trigger this. It could be a faulty sensor, wiring issue, module fault, etc. To see what specifically is causing the light to come on the vehicle will need to be tested with a scan tool that connects to the vehicle. This test will provide a trouble code that describes what specific system is having the problem. If you can have the vehicle scanned and can give me the code, I will be able to tell you specifically what is wrong with it. If you do not have a scan tool then you can bring your vehicle to any auto part store and they will scan it for free and give you the trouble code. I would do this ASAP so that we can determine what the problem is and keep any other problems from happening.

have you tried to clear the codes yet and test drive?

Take the positive post off from the battery and leave off for about 5 minutes and put back on to reset the codes please.

after this please let me know if any codes comes back

if lights are on there should be codes

can you see each wheel speed in your scanner?

The dash assembly must have a short in the wiring

theres is something wrong with one of the sensor, computer or system, your going to need a better scanner to diagnose this
