SRS ABS AND BAT LIGHT

ALL LIGHTS CAME ON CHANGED BATTERY AFTER TWO DAYS IT ALL STARTED UP TAC AND SPEED GOING CRAZY

You are fighting a low battery/voltage problem.
I would suggest you go have a load test done to verify wether it is the battery or alternator.
Once it is cleared up, you will then have to have someone with the appropriate scanner clear your fault code so the warning lights will go on.
