What could be the reason why my ABS light is on? I had three different things come up. Speed sensor, module and ABS pump. I am confused. Do I have to go to the dealer to find out why it is on?

They are new on Amazon, the pumps don't go out that often on these cars

Please let us know what happens.

Cheers, Ken

Yep that is a pump code,

Here are some diagrams to help you get it changed out.

Make sure you use a line wrench

Some you do others you don't. Do you have regular size tires on the car then you should be okay.

Please let me know though,

Best, Ken
