I hooked up an after market stereo and now my speedometer lights don't work. Know why? On my 01 echo.

No, the stereo has an ON/OFF switch. If you connect the power for the stereo on the ignition side of the fuse box when you turn off the ignition switch/key hen power will be automatically cut off to the stereo even if you leave the switch on at the stereo.

It can be the problem with cd player mechanism,on many cases just removing the cd player system out of dash and servicing the unit helps to take care of such problems.

You have multiple problems. Make sure the brake fluid is at the proper level. Most of the time when I see this and the fluid is correct with no other mechanical issues it turns out there is a short due to an after market alarm that was installed incorrectly. Make sure you don't have a caliper sticking on one of the wheels which will cause the ABS and Brake Lights to come on. You'll also want to make sure your emergency brake isn't stuck. The ABS module malfunctioning would explain the ABS light and the Brake Light but not the speedometer issue. I have given you a lot of things to check because you need to be sure those are all working correctly. Because you added the Speedometer issue this is most likely going to be a short somewhere in the circuit or a possible issue with the ECM. It is possible a faulty ABS module could cause this, before you go get a new one though, try locating one in a local Junk yard and switch it out. If the lights go out you know that is the problem and you can go get a new one, I don't recommend using junk yard ABS parts for anything other than testing. With those lights on you can go to Auto Zone or Advance auto and ask them to connect the code reader to the vehicle and get a better idea of where you need to look.
