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

• Covers the 2013 Nissan Pathfinder Model R52 Series / 2013 Pathfinder NAM, including the VQ35DE 3.5L V6 and both 2WD and 4WD configurations
• Nissan factory publication SM3E-1R52U0, Edition and Revision October 2012
• Supplied as 57 PDF files totaling 4,910 pages, including the front matter/index and 56 individual service sections
• Powertrain coverage identifies the RE0F10E CVT, 2WD transaxle codes 3WX0B/3WX0D, 4WD codes 3WX0C/3WX0E, plus the TY21C transfer and R145K1 rear final drive used on 4WD models

Vehicle, Powertrain, and Chassis Coverage

This is far more than the accelerator-control and seat-memory material covered by the earlier description. Engine repair information for the VQ35DE includes camshaft valve-clearance checks, compression testing, intake and exhaust components, fuel injectors and fuel tubes, intake valve timing control, front timing chain case and timing chain work, cylinder heads, cylinder block service, engine mounts, and separate 2WD/4WD engine-assembly removal procedures.

The RE0F10E section covers the TCM, ROM assembly, input/primary/output speed sensors, primary and secondary pressure sensors, pressure-control solenoids, torque-converter clutch control, shift-lock system, CVT cooler and warmer circuits, fail-safe/protection strategies, stall testing, fluid servicing, transmission removal, and service-data limits. For 4WD vehicles, the driveline material adds the TY21C transfer, electric controlled coupling, 4WD control unit, 3FCJ-CVJ rear propeller shaft, and R145K1 rear final drive, including unit disassembly, bearing/preload checks, oil service, and control-unit characteristic writing.

Chassis repair extends through front and rear suspension, wheel alignment, hubs and drive shafts, hydraulic steering, VDC/ABS brake control, service brakes, parking brake, wheels and TPMS. The separate Body Repair section covers high-strength and ultra-high-strength steel, corrosion protection, structural replacement operations, body center marks, and dimensional alignment data for the engine compartment, underbody, passenger compartment, and rear body.

Electrical Diagnosis, ADP, and Wiring

Electrical diagnosis is organized around Nissan control-unit reference values, connector-terminal checks, DTC indexes, fail-safe logic, circuit diagnosis, wiring diagrams, and CONSULT functions. Covered systems include ECM and TCM control, CAN/LAN communication, BCM and IPDM E/R functions, Intelligent Key/NATS, charging and starting, exterior/interior lighting, power windows, automatic back door, HVAC control, SRS and Occupant Classification System, steering control, TPMS, sonar, audio/navigation, and Around View Monitor.

The 160-page Automatic Drive Positioner section remains an important part of the set. It documents the driver seat control unit, ADP control unit and BCM interaction along with manual positioning, memory, entry assist, exit assist, and Intelligent Key interlock functions. Separate ADP wiring is provided for vehicles with and without Around View Monitor, followed by control-unit reference values, DTC diagnosis, initialization, memory storing, individual seat/steering/mirror sensor diagnosis, and component removal.

Representative technical drawings and schematics include the RE0F10E Transaxle Cross-Sectional View, CVT Fluid Cooler Schematic, TY21C 4WD System Wiring Diagram - With Around View System and corresponding without-Around-View version, Automatic Drive Positioner System Diagram, SRS Air Bag System Diagram, and the Around View Monitor Calibration Flowchart.

Factory Procedures, Tools, and Service Data

Factory procedures cover work that often goes beyond routine owner maintenance: engine assembly removal and internal repair, timing-chain service, CVT removal and fluid-level adjustment, TCM/transaxle characteristic-data writing, transfer and rear-final-drive repair, 4WD unit-characteristics writing, steering and suspension repair, brake hydraulic service, TPMS transmitter ID registration, power-window initialization, automatic back-door calibration, Around View camera calibration, and SRS Occupant Classification System zero-point reset. The manual also documents A/C refrigerant recovery/recharging, leak diagnosis, oil adjustment after component replacement, and performance testing.

Hard specifications are provided throughout. The 3,498 cc VQ35DE has a 10.6:1 compression ratio, with compression pressure listed at 1,275 kPa (185 psi) standard and 981 kPa (142 psi) minimum at 300 rpm. Accelerator pedal stroke is 50.5–53.5 mm, with pedal height at 169.2 ± 5 mm. USA/Canada fluid data lists 4.8 L engine oil with filter replacement and approximately 8.8 L of Genuine Nissan CVT Fluid NS-3; the manual carries a separate Mexico fluid table. A/C specifications call for 0.85 ± 0.05 kg of HFC-134a (R-134a) and 180 mL of A/C System Oil Type S (DH-PS).

Special-tool tables identify application-specific equipment rather than leaving tooling assumptions to the technician. Examples include KV311039S0 for CVT fluid changing and adjustment, KV10116200 (J-26336-A) for valve-spring service, and J-41810-NI refrigerant identification equipment for checking R-134a purity and system contamination.

Repair-Specific Notes and Scope

Several precautions show why the model-specific repair information matters. Nissan treats the accelerator pedal as a non-disassemblable electronic assembly and warns against dropping, impacting, or exposing it to water; disconnecting its position-sensor connector also requires the specified accelerator-pedal released-position learning. On the RE0F10E, battery voltage remains applied to the TCM even with the ignition switched off, and the manual specifically warns against bending or breaking TCM connector pins; TCM or transaxle replacement also involves stored characteristic data rather than simple parts substitution. In the A/C section, mixing CFC-12 with the specified R-134a refrigerant is identified as a likely cause of compressor malfunction.

One scope limitation should be clear before purchase: the master index references Hybrid Control (HBC), Hybrid Battery (HBB), Hybrid Brake (HBR), Suspension Control (SCS), Seat Belt Control (SBC), and Adjustable Pedals (AP), but those section PDFs are not present in the supplied 57-file archive. Do not assume this set includes those omitted groups or hybrid-system repair coverage.

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 when performing these repairs.
