Computer series for Corolla 1997

Friends, Nesto of your help or some advice. The 1997 Corolla computer gave me a fault and they changed it to me, however the one that put me gives me a failure that loses the vehicle, but they tell me that it is for a automatic cash car. And to buy another they ask me for a series of the vehicle, but the mechanic lost my original computer.

Greetings. Will you have the vin of the vehicle? The 17 digits. Serial number or chassis ...
