Engine check and slip indicator light stay on

My car is listed above petrol. Yesterday when I was driving on high way the slip indicator and engine check yellow light were on. I tried to turned off and restart engine after I arrived my destination later. But the lights are still on. When I turn on the key, the engine check light stay on after dashboard finish self check. Then when I move the car the slip indicator shows again and stay on all the time.
I have disconnected the negative of battery for more than five minutes and check the gas cap but it doesn't work.
I tried to use jump wire to get fault code. The ABS light flashing shows 41 which means abnormal voltage.
What should I do next step？
Plus, all other performance of my car is good.
Thanks,
Jack
