1999–2002 Nissan Skyline R34 & GT-R Service Manual (P/N SM8E-0R34J0)

This Nissan service manual covers the 1999–2002 Skyline R34 GF-HR34, GF-ER34 and GF-ENR34 series, including coupe, sedan and 25GT TURBO variants. It combines the original English publication, SM8E-0R34J0, with Supplement-I for the GF-BNR34 GT-R and GT-R V spec.

• Engine controls: RB20DE, RB25DE, RB25DET and RB26DETT diagnosis, idle-speed and ignition-timing adjustment, air/fuel-ratio checks, fuel-pressure inspection and ECM signal references.

• Automatic transmissions: RE4R01B/4AT and Dual matic M-ATx line-pressure and stall tests, shift-lock circuits, fail-safe operation and clutch-and-band charts.

• GT-R driveline: ATTESA E-TS and V spec ATTESA E-TS PRO hydraulic bleeding, evacuation, pressure and lock checks, plus actuator and accumulator replacement.

• Chassis and restraints: Anti-lock Brake System (ABS), Traction Control System (TCS), Electric SUPER HICAS and Supplemental Restraint System (SRS) diagnosis, warning-lamp interpretation and circuit diagrams.

• Body electrical: Central door locks, remote control entry, power-window and Xenon headlamp troubleshooting, sunroof circuits, plus GT-R NATS and multi-function display diagnosis.

• Climate control: Fully automatic air-conditioner performance and gauge-pressure tests, built-in self-diagnosis, door-actuator checks and deodorizing-filter replacement.

• Service references: Clutch, manual-transmission, final-drive, axle, suspension and steering specifications, component torque tables and appended maintenance checklists.

This manual suits technicians and experienced owners who can interpret electrical diagrams and use circuit testers, pressure gauges and the applicable Nissan CONSULT functions.

Engine Control and Transmission Diagnostics

The ECM/TCM terminal layouts and input/output tables cover mass air flow, knock and crank/cam position signals. For automatic-transmission models, they distinguish the integrated RB20DE/RB25DET controller from the separate RB25DE ECM and TCM, helping you match electrical tests to the correct configuration.

Diagnostic Test Modes I and II sit alongside CONSULT data-monitor, active-test and function-test procedures. Vacuum Hose Drawings and Symptom Matrix Charts connect sensor and actuator faults with starting, idle and drivability complaints.

The automatic-transmission section adds Shift Pattern Charts and line-pressure test interpretation, including the pressure gauge identified as special service tool ST2505 S001. Review the factory safety precautions before fuel-pressure checks or live electrical diagnosis.

GT-R Transfer, A-LSD and Mechanical Coverage

Supplement-I separates standard GT-R E-TS/ABS from V spec ATTESA E-TS PRO, which combines transfer control, the active limited-slip differential and ABS. Hydraulic Circuit Diagrams and component-location views support diagnosis of pressure and driveline complaints.

Actuator, accumulator and hydraulic-line removal and installation procedures are included. The GT-R checks warn that prolonged direct-power testing can overheat the E-TS motor, while impact or dropping can damage the G sensor.

Mechanical scope: Service-data tables cover the FS5W71C, FS5R30A and ETX13A manual transmissions, front and rear final drives, propeller shafts, drive shafts, suspension parts and steering gear. These tables are not complete engine or transmission overhaul instructions; Nissan directs service work outside this publication to separate Japanese manuals.

Body Electronics and Diagnostic Access

ABS fault-code retrieval uses the diagnostic connector; SRS airbag self-diagnosis uses the ignition and driver-door switches. The restraint chapter also covers CONSULT diagnosis and airbag and seat-belt pre-tensioner fault charts. Its precautions warn that an ordinary circuit tester can trigger airbag deployment.

Remote entry and NATS: The manual ID Code Entry Procedure covers replacement or additional remote transmitters. GT-R NATS diagnosis requires CONSULT with NATS software; initialization and key-registration details are referred to the separate CONSULT NATS operation manual.

The multi-function display section includes sensor checks, symptom diagnosis and initial throttle-position adjustment.

A Preview of Fuel-Pressure and E-TS Electrical Data

These fuel-system and solenoid values are a small sample of the diagnostic specifications in the manual.

For RB20DE, RB25DE and RB25DET fuel-pressure inspection, the reference is 0.25 MPa (2.5 kg/cm²) at idle, or 0.29 MPa (3.0 kg/cm²) with the pressure-regulator vacuum hose disconnected.

In the GT-R E-TS/ABS component checks, resistance across the disconnected E-TS solenoid is approximately 6 Ω; the fail-safe solenoid is approximately 11 Ω.

PDF Search, Bookmarks and Included Sections

Text access and diagram detail: OCR search is available through much of the base manual, and the maintenance checklists have searchable text; Supplement-I has no text layer. Bookmarks cover the base chapters and the starts of both additions. Small circuit labels need zooming, and some diagrams are presented sideways.

One printable 447-page PDF in English contains the 230-page base manual, 204-page Supplement-I and 13 pages of maintenance checklists. Covers, introductory pages and the supplement's two blank pages are already included in these totals.
