good morning my name is ***** ***** I will assist
if you have a used pcm, that pcm needs to be flashed or re programmed to your vehicle to operate properly. some shops can do this if they have the equipment. the pcm needs to see your vin number and all the options to work.
this all assumes that the pcm is the actual failure. what lead you to replace the pcm???

Motor starts irratic idle . But still drives smoothly. Replaced throttle body coil packs .o2 sensor tps cam and crank sensors but still no difference .fuel pump was checked for pressure aswell. Upon further inspection i discovered the heater core is leaking and runnind down the foot well and pcm was wet . I used my latest launch scan tool to do a parameter reset and try and swap ecu but it didnt five me that functionality

No cant flash scan tool doesnt allow me to get into security ...
Expert:  Roy replied 1 year ago.
ok, then you need a shop with flashing capability. there are plenty around and runs about 100 to 125. hopefully the used pcm will accept it. Roy
