While I was driving my ABS light came on my dashboard and then the odyssey started to slow down so I pulled over and now it's not moving and it's not starting up also now all the lights on the dashboard are all on. Does anyone know what has happened and how to fix it?

 

First thing to do is to check the voltage on the battery.
Replace if necessary. Check oil level.
Then check all the fuses with a test light.
On each fuse there are two test points. One above each blade or leg of the fuse
With key on and the clip side of test light on ground, probe each test point
If both test points lights up then fuse is good
If only one side of fuse lights up then fuse is blown
If no lights then no power to fuse

Note: Am suspecting the alternator is faulty.
