    2. NG : GO TO 2.
  2. CHECK DETENTION SWITCH HARNESS 
    1. Turn ignition switch OFF.
    2. Disconnect CVT device [detention switch (key)] connector and "key switch and key lock solenoid" connector.
    3. Check continuity between CVT device [detention switch (key)] connector M57 terminal 5 (B/R) and key switch and key lock solenoid connector M28 terminal 4 (B/R).
      1. 5 (B/R) - 4 (B/R) : Continuity should exist. 
    4. Check continuity between CVT device [detention switch (key)] connector M57 terminal 5 (B/R) and ground.
      1. 5 (B/R) - Ground : Continuity should not exist.

  4. CHECK DETENTION SWITCH SIGNAL CIRCUIT HARNESS CONTINUITY 
    1. Disconnect driver seat control unit connector.
    2. Check continuity between driver seat control unit connector B303 terminal 21 (R/L) and CVT device [detention switch (key)] connector M57 terminal 6 (L).
      1. 21 (R/L) - 6 (L) : Continuity should exist. 
    3. Check continuity between driver seat control unit connector B303 terminal 21 (R/L) and ground.
      1. 21 (R/L) - Ground : Continuity should not exist.
