93 GCLtd 5.2 error codes 12, 32, 34, 55

Can anybody help me with these error codes - I have just bought the vehicle and would like to know what they are. The codes are 12, 32, 34 & 55 - That's if I am reading them correctly

Thanks

12= Problem with battery connection.
32= An open or shorted condition in the EGR solenoid circuit.
34= An open or shorted condition detected in the cruise control vacuum or vent solenoid circuits.
55= Completion of fault code display (telling you that there is no more fault codes).

Much appreciated. Is this info available in the Haynes Workshop manual? If not where can it be found? Thanks
