In this work, we make a detailed discussion on the phenomenology of the scotogenic Dirac model, which could accommodate the Dirac neutrino mass and dark matter. We have studied the lepton-flavor-violating (LFV) processes in this model, which are mediated by the charged scalar φ± and heavy Dirac fermions Ni. We select the heavy Dirac fermion N1 as dark matter candidate and find the correct relic density will be reached by annihilating through Yukawa coupling yχ. After satisfying LFV and dark matter relic density constraints, we consider the indirect detections of dark matter annihilating into leptons. Then we make a detailed discussion on the dark matter direct detections. The current and future direct detection experiments have been used to set constraints on the Yukawa couplings and masses. At last, we have briefly discussed the collider signal searching in this model, the exclusion limits from collider on mN1 and mφ have provided a complementary detecting capability compared to the LFV and dark matter detections.
