When trying to accelerate the car will start to go and then around 6-10 MPH the brakes will lock up and the car can’t go anywhere. If I let off gas a second or two will go by and then they will release, and the car can idle drive. Eventually the RSC error code comes on ABS light and traction control.

Hi,

What I recommend is this: We need to know what diagnostic trouble codes are stored. In this case, the can-bus needs to be scanned.

CAN stands for controller area network. Basically, the different modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them. This is where we need to start. Otherwise, it will become a guessing game.

Here is a link showing how it's done:

Let me know if that is something you can do or have done. If you can, let me know what codes are stored.

Let me know.

Take care,

joe
