then reconect,then sit in car put foot to floor on gas pedal then turn on ignition do not start engine just wait for a double beep depends on how many faults are on ecu shouldnt take more than 20,30 secs then take foot of gas turn off ignition and then start engine fault light should reset,if it doesnt reset you may have a map senser prob,and will need to be hooked up to a diagnostic machine
