BUICK LESABRE SECURITY LIGHT

Can Anyone Tell Me What To Do If The Security Light Keeps Flashing? I Was Told It Goes Into Hydralock And Cannot Be Fixed Except By Dealer....

Security Light Is On And When I Accelerate On The Gas Pedle The Tempeture And Voltage Light Comes On And My Car Dies Out

May I Please Get The Wiring Diagram Or Schematic For The Passkey 3 System Or The Pass Lock 3 System I Can't Remember What It's...
