Nissan Pathfinder R52 2013 Service Manual (P/N SM3E-1R52U0)

Nissan factory service manual for the 2013 Pathfinder R52 Series / Pathfinder NAM, covering the VQ35DE 3.5L V6 in 2WD and 4WD configurations. P/N SM3E-1R52U0, edition and revision October 2012.

PDF Sections, Search, and Diagram Detail

Text search and navigation: Service text is searchable, but labels within many wiring diagrams are embedded as images and cannot be found through text search. Embedded bookmarks are available in 41 of the 57 PDFs; internal destinations checked in those files lead to the corresponding topics. Cross-file links depend on the PDF reader and keeping the extracted files together. Small labels in the wiring diagrams checked require zooming.

The ZIP download contains 57 printable PDFs totaling 4,910 pages: 4,900 pages across 56 service sections, plus the 10-page front matter/reference file already included in that total. The front matter contains the master index, foreword, feedback form, and quick-reference charts.

Powertrain, Chassis, and Control-System Coverage

The following selected coverage highlights outline the repair and diagnostic content rather than reproduce the full contents list. Other included topics range from sunroof service to wiper and washer diagnosis.

• Engine repair: Step-by-step procedures for timing-chain service, cylinder-head and cylinder-block work, valve-clearance inspection, compression testing, and engine removal.

• CVT diagnosis and service: RE0F10E fault diagnosis, stall testing, fluid-level adjustment, cooler servicing, transaxle removal, and TCM/transaxle characteristic-data writing.

• 4WD driveline: TY21C transfer repair, electric controlled coupling diagnosis, rear propeller-shaft service, and R145K1 rear-final-drive disassembly and adjustment.

• Chassis and body repair: Suspension, wheel alignment, hubs, drive shafts, steering, VDC/ABS, service brakes, parking brake, TPMS, and structural body repair.

• Electrical troubleshooting: DTC indexes, connector-terminal checks, control-unit reference values, CONSULT functions, wiring diagrams, and CAN/LAN communication diagnosis.

• Comfort and calibration: Automatic Drive Positioner diagnosis, power-window initialization, automatic back-door calibration, Around View camera calibration, and Occupant Classification System zero-point reset.

This manual suits technicians familiar with electrical testing, CONSULT diagnostics, and the use of Nissan-specific service tools.

VQ35DE Mechanical Repair and Engine Controls

Engine procedures cover intake and exhaust components, fuel injectors and fuel tubes, intake valve timing control, the front timing chain case, engine mounts, and separate 2WD/4WD engine-assembly removal instructions.

Cooling-system information includes overheating cause analysis, leak checks, coolant replacement, and radiator, water-pump, and thermostat service. Lubrication coverage adds oil-pressure inspection, oil-pump disassembly, and oil-cooler removal.

Engine-control diagnosis addresses fuel-pressure checks, misfire and mixture faults, EVAP components, and throttle-related learning procedures. These sections connect fault-code diagnosis with component checks rather than relying on a code list alone.

The accelerator pedal is a non-disassemblable electronic assembly that must be protected from impact and water. Disconnecting its position-sensor connector also calls for the specified accelerator-pedal released-position learning.

RE0F10E CVT and 4WD Driveline

The CVT section documents the TCM and ROM assembly, input/primary/output speed sensors, primary and secondary pressure sensors, pressure-control solenoids, torque-converter clutch control, and shift-lock system. Cooler and warmer circuits, fail-safe strategies, and protection functions are explained alongside the diagnostic procedures.

TCM or transaxle replacement involves stored characteristic data. The replacement procedures explain the required data handling, helping distinguish a completed mechanical installation from the additional electronic setup.

Battery voltage remains applied to the TCM with the ignition switched off, and its connector pins are vulnerable to bending or breakage.

For 4WD models, the driveline sections cover the 4WD control unit, 3FCJ-CVJ rear propeller shaft, bearing and preload checks, oil service, and unit-characteristics writing.

Steering, Brakes, and Structural Repair

Chassis coverage includes hydraulic pump electric power steering, hydraulic bleeding, steering-column service, front and rear suspension, and wheel and tire diagnosis. Brake information includes hydraulic servicing and VDC/ABS control-system diagnosis.

The Body Repair section addresses high-strength and ultra-high-strength steel, corrosion protection, structural replacement operations, and body center marks. Dimensional alignment data covers the engine compartment, underbody, passenger compartment, and rear body.

Electrical Systems, ADP, and Calibration

Electrical coverage extends through ECM and TCM control, BCM and IPDM E/R functions, Intelligent Key/NATS, charging and starting, exterior/interior lighting, HVAC control, sonar, and audio/navigation.

The Automatic Drive Positioner material explains driver-seat control unit, ADP control unit, and BCM interaction. Manual positioning, memory, entry assist, exit assist, and Intelligent Key interlock functions are supported by initialization, memory-storing, seat/steering/mirror sensor diagnosis, and component-removal procedures.

Separate ADP wiring diagrams cover vehicles with and without Around View Monitor. Selecting the matching diagram matters because the control-unit connections differ with the camera-system configuration.

Illustrated references include the RE0F10E Transaxle Cross-Sectional View, CVT Fluid Cooler Schematic, and TY21C 4WD System Wiring Diagram, with and without Around View System. Other examples are the Automatic Drive Positioner System Diagram, SRS Air Bag System Diagram, and Around View Monitor Calibration Flowchart.

A/C Service, Tools, and Coverage Limits

A/C procedures cover refrigerant recovery/recharging, leak diagnosis, oil adjustment after component replacement, and performance testing. Mixing CFC-12 with the specified R-134a refrigerant can cause compressor malfunction.

Special-tool tables identify equipment such as KV311039S0 for CVT fluid servicing, KV10116200 (J-26336-A) for valve-spring work, and J-41810-NI for refrigerant identification.

Hybrid-system repair is not included in the supplied files. The master index lists HBC, HBB, HBR, SCS, SBC, and AP, but the corresponding PDFs are absent. The index entries do not establish coverage of those groups.

SRS, brake hydraulic, refrigerant, powered-seat/steering, and electronically controlled driveline work carries specific Nissan safety requirements. Follow the precautions in the applicable section and use the specified diagnostic and service equipment.

Examples of Compression and Fluid Specifications

For VQ35DE compression testing, the specifications list 1,275 kPa (185 psi) as standard and 981 kPa (142 psi) as minimum at 300 rpm.

The USA/Canada fluid table lists approximately 4.8 L of engine oil for drain-and-refill with filter replacement and 8.8 L of Genuine Nissan CVT Fluid NS-3. Mexico has a separate fluid table.

A/C specifications list 0.85 ± 0.05 kg of HFC-134a (R-134a) and a total system oil capacity of 180 mL of A/C System Oil Type S (DH-PS); the component-replacement procedures address oil adjustment separately.
