Is there 1.0 Ω or less?

YES: Door switch

The FL_DOOR_SW, FR_DOOR_SW, RL_DOOR_SW, and RR_DOOR_SW wires are OK. Replace the bad door switch.

YES: Power tailgate closer unit (with power tailgate)

The T/G_SW wire is OK. Faulty Power tailgate closer unit circuit. Check for Power tailgate control unit DTCs.
