OK: System is OK.
NG: GO TO 2.

CHECK DETENTION SWITCH POWER SUPPLY CIRCUIT HARNESS
1. Turn ignition switch OFF.
2. Disconnect A/T device (detention switch) connector and key switch and key lock solenoid connector.
3. Check continuity harness between A/T device (detention switch) connector M97 terminal 6 (PU/W) and key switch and key lock solenoid connector M64 terminal 4 (PU/W).
  1. 6 (PU/W) - 4 (PU/W): Continuity should exist.
4. Check continuity harness between A/T device (detention switch) connector M97 terminal 6 (PU/W) and ground.
  1. 6 (PU/W) - Ground: Continuity should not exist.
OK or NG
1. OK: GO TO 3.
2. NG: Repair or replace harness between A/T device (detention switch) and key switch and key lock solenoid.

OK or NG
1. OK: GO TO 4.
2. NG: Replace detention switch.
CHECK DETENTION SWITCH SIGNAL HARNESS
1. Disconnect BCM connector.
2. Check continuity between BCM connector M4 terminal 8 (G/OR) and A/T device (detention switch) connector M97 terminal 7 (G/OR).
  1. 8 (G/OR) - 7(G/OR): Continuity should exist.
3. Check continuity harness between BCM connector M4 terminal 8 (G/OR) and ground.
  1. 8 (G/OR) - Ground: Continuity should not exist.
OK or NG
1. OK: Replace BCM.
2. NG: Repair or replace harness between BCM and A/T device (detention switch).
