1.CHECK GROUND CONNECTION

1. Turn ignition switch OFF.
2. Check ground connection B31 and ground cable connections. Refer to “Ground Inspection” in Circuit Inspection.

Is the inspection result normal?
YES >>GO TO 2.
NO >>Repair or replace damaged parts.
2.CHECK SEQUENCE SOLENOID VALVE CIRCUIT

1. Disconnect TCM harness connectors.
2. Check resistance between TCM vehicle side harness connector terminal and ground.

   TCM vehicle side harness connector | Ground | Condition | Resistance (Approx.)
   Connector | Terminal
   B46 | 53 | Ground | Transmission oil temperature: 20°C (68°F) | 6.6–7.4Ω
   Transmission oil temperature: 50°C (122°F) | 7.3–8.3Ω
   Transmission oil temperature: 80°C (176°F) | 8.1–9.2Ω

Is the inspection result normal?
YES >>GO TO 6.
NO >>GO TO 3.
3.CHECK SEQUENCE SOLENOID VALVE

1. Disconnect transmission unit harness connectors.
2. Check sequence solenoid valve. Refer to Component Inspection (Sequence Solenoid Valve) (GT-R certified NISSAN dealer).

Is the inspection result normal?
YES >>GO TO 4.
NO >>Repair or replace damaged parts.
4.CHECK HARNESS BETWEEN TCM AND TRANSMISSION (SEQUENCE SOLENOID VALVE) (PART 1)
Check continuity between TCM vehicle side harness connector terminal and transmission unit vehicle side harness connector terminal.

TCM vehicle side harness connector | Transmission unit vehicle side harness connector | Continuity
Connector | Terminal | Connector | Terminal
B46 | 53 | B49 | 6 | Existed

Is the inspection result normal?
YES>>GO TO 5.
NO >>Repair or replace damaged parts.
5.CHECK HARNESS BETWEEN TCM AND TRANSMISSION (SEQUENCE SOLENOID VALVE) (PART 2)
Check continuity between TCM vehicle side harness connector terminal and ground.

TCM vehicle side harness connector | Ground | Continuity
Connector | Terminal
B46 | 53 | Ground | Not existed

Is the inspection result normal?
YES>>GO TO 6.
NO >>Repair or replace damaged parts.
6.CHECK INTERMITTENT INCIDENT
Refer to Intermittent Incident.
