The electrical resistivity of PrCo2Si2 with a long-period commensurate spin structure has been measured in a magnetic field up to 9 Tesla, together with the heat capacity up to 5 Tesla. The resistivity changes drastically with step-like jumps at the successive transition points accompanying the change of the antiferromagnetic propagation vectors. From the resistivity measurements, four distinct phases are confirmed below the antiferromagnetic transition temperature. A temperature-magnetic field phase diagram of PrCo2Si2 is presented.
