THE FIRST THING THAT HAPPEN THE RT ABS BRAKE GRAB AND THE ABS LIGHT COME ON THEN THE POWER STARTED GETTING TO A POINT THAT THE VEHICLE FINELY QUIT. THE VEHICLE WAS TOW TO THE DEALER.

WHAT IS THE VOLTAGE ON THE BLACK AND YELLOW WIRE, THAT RUN TO THE INTERLOCK TRANSMISSION SOLENOID.I 'M GETTING A READING OF 12 VOLT WHEN A DEALER CAN'T FIGURE IT OUT. WHEN I WAS A AG REPAIRMAN FOR GM I HAD ACCESS ALL THE MILLION WORTH OF EQUIPMENT, TO CHECKOUT THE WHOLE VEHICLE. BUT I RETIRE. SO I DON'T HAVE THAT ACCESS ANYMORE. SO I'M BACK TO SCAN TOOL AND A VOLT AND OHMMETERS. THE CAR IS MY NIECE'S SO I'M NOT WORRIED ABOUT IT.
