Nissan Skyline R34 1999–2002 Service Manual (P/N 8E-0R34J0)

This 447-page factory reference is the primary diagnostic resource for the 1999–2002 Nissan Skyline R34 series. Covering the GF-HR34, GF-ER34, and GF-ENR34 chassis, it breaks down the systems for the 2-door Coupe, 4-door Sedan, and 25GT Turbo variants.

Printed directly from the original Nissan 8E-0R34J0 1998 publication, this PDF provides detailed terminal references and circuit layouts. Having access to original factory resistance values allows technicians to trace voltage drops directly across the chassis harness rather than relying on generic aftermarket literature. This distinct shop-floor advantage actively prevents misdiagnosis and streamlines the repair process on complex electrical networks.

Coverage includes:

• RB20DE, RB25DE, and RB25DET powerplants
• Dual matic M-ATx and 4AT transmission systems
• 47 pages of exact wiring diagrams
• 48 pages of engine control diagnostic terminal references
• 24 pages of transmission shifting schematics
• Anti-lock Brake System (ABS), Traction Control System (TCS), Supplemental Restraint System (SRS), Electric SUPER HICAS steering, Xenon headlamps, remote control entry, central door locks, and the fully automatic air conditioner
• FS5R30A manual transmission, FS5W71C manual transmission, front and rear final drives, propeller shafts, drive shafts, suspension parts, steering gear, and sunroof system

To facilitate advanced diagnostics, the text incorporates essential visual aids beyond basic schematics, including vacuum hose drawings, symptom matrix charts, component parts location views, clutch and band charts, shift pattern charts, and circuit diagrams. For independent shops and DIYers aiming to bypass expensive dealership visits, the documentation outlines critical step-by-step troubleshooting procedures. You will find specific instructions for manual base idle speed and ignition timing adjustments, executing safe fuel pressure inspections, and performing complete automatic transmission line pressure and stall tests. Furthermore, it details how to retrieve ABS and SRS self-diagnostic malfunction codes via the data link connector without a proprietary CONSULT scanner, and covers the manual ID code entry procedure for new remote controllers.

Engine Control and Transmission Diagnostics

Rather than basic overviews, this documentation dives straight into the ECM and TCM interaction. It maps out the exact signal flows for the mass air flow sensor, knock sensors, crank position signals, and solenoid-driven hydraulic actuators. You will find complete procedures for Diagnostic Test Mode I and II, alongside instructions for utilizing the Nissan CONSULT interface to run active tests and monitor system health.

Working with high-pressure fuel systems or probing ECM terminals carries inherent risks; always review the factory safety protocols outlined in these pages before executing live diagnostic tests or component replacements. The precise terminal layouts ensure you can accurately track signal voltage inputs and outputs without guessing pin locations.

Specification and Reference Values

Accurate diagnostics require exact baseline numbers. This manual provides the complete set of factory reference values for the R34 series, including:

• Cold Lash Intake Valve Clearance: 0.15–0.19 mm (0.006–0.007 in)
• Coolant System Capacity: 9.4 liters
• Base Fuel Pressure (at idle): 0.25 MPa (2.5 kg/cm2)

Like any professional OEM service publication, the documentation also covers in-depth shift schedule charts and line pressure test specifications vital for automatic transmission maintenance.
