A Dalitz plot analysis of approximately 13 000 D[subscript s] + decays to pi + pi - pi + has been performed. The analysis uses a 384 fb-1 data sample recorded by the BABAR detector at the PEP-II asymmetric-energy e+e- storage ring running at center of mass energies near 10.6 GeV. Amplitudes and phases of the intermediate resonances which contribute to this final state are measured. A high precision measurement of the ratio of branching fractions is performed: B(D[subscript s][superscript +]-->pi[superscript +]pi[superscript -]pi[superscript +])/B(D[subscript s][superscript +]-->pi[superscript +]pi[superscript -]pi[superscript +])=0.199±0.004±0.009. Using a model-independent partial wave analysis, the amplitude and phase of the S wave have been measured.
