What I did for something like that was just connect one end of the multimeter to the socket, and slowly slide the other end across the DIP socket, one side then the other. With the multimeter in continuity mode, it'll beep as soon as you hit the pin the socket is connected to. If you don't get any beep, there's your faulty pin. If all pins get beeps, the socket is connected to the controller without a problem. For this purpose, it's not really important to know which pins go where, just that they are all connected somehow to the chip.
From memory a keyboard error is different to a 'no keyboard detected' error, so it looks like it could be some other pins on the keyboard controller that are suspect.
