Dodge RAM Truck 1500 2002 Service & Diagnostic Manual Set (P/N 81-370-02059)

The service manual provides mechanical repair procedures, while the diagnostic booklets trace faults through system tests, connector pinouts, and schematics. The diagnostic booklets refer back to the service information for component removal and repair.

Application note: The gas-powertrain booklet contains a conflicting model reference in its introduction. Match its diagnostic procedures to the engine and circuit application identified within each test.

PDF Search, Bookmarks, and Diagram Detail

Text navigation and schematics: Text sections support search, but many labels within wiring and schematic graphics are not searchable. The five technical documents have embedded bookmarks. Small labels in dense powertrain schematics require zooming for comfortable reading. Keep the extracted files together to preserve relative links between documents; cross-file navigation depends on the PDF viewer.

The ZIP contains seven printable PDFs totaling 3,247 pages, including the separate two-page cover and foreword, one-page launch page, and two service-comment pages within the service manual.

Powertrain Repair, Chassis Service, and Electrical Diagnosis

These selected coverage highlights outline the main workshop areas. Further topics include exhaust-system service and windshield wiper/washer diagnosis.

• Engine repair: Compression and cylinder-leakage testing, cylinder-head service, timing-chain procedures, and internal inspection for the covered gasoline engines.

• Transmission and transfer cases: NV3500, 46RE, and 45RFE disassembly and assembly, clutch service, hydraulic tests, and NV241 GENII/NV243 repair procedures.

• Suspension and axles: Wheel alignment, hub/bearing replacement, control-arm service, differential setup, and pinion/ring-gear inspection and adjustment.

• Brake diagnosis: Base-brake service, TRW EBC 125 rear-wheel antilock and EBC 325 ABS troubleshooting, plus adjustable-pedal diagnostic procedures.

• Electrical fault tracing: DRB III tests, PCI-bus communication diagnosis, connector pinouts, component locations, and system-specific wiring diagrams.

• Body and climate control: Door and glass service, body-structure repair information, HVAC component replacement, and air-conditioning performance and leak testing.

The service manual was prepared for professional automotive technicians involved in daily repair work; the diagnostic routines assume access to a DRB III and appropriate test equipment.

Engine, Fuel, and Cooling Work

Separate engine chapters provide step-by-step removal, inspection, and installation procedures, with engine-specific valve-train and timing information. Compression and cylinder-leakage diagnosis charts connect test results with possible mechanical faults, supporting fault isolation before major disassembly.

Fuel-system coverage includes fuel-pressure diagnosis, injector service, and evaporative-emissions testing. Cooling sections cover pressure testing, thermostat and water-pump service, flushing, and transmission-oil-cooler work. The lubrication chapter identifies fluids for the engine, transmission, transfer case, and differentials; maintenance schedules are referred to the vehicle’s Owner’s Manual.

Transmission Repair and Adaptive Controls

Mechanical coverage extends to synchronizer and shaft work in the NV3500, clutch and band service in the 46RE, and clutch-pack, oil-pump, and valve-body work in the 45RFE.

The service manual’s RFE teardown chapter is labeled 45RFE. The separate 45RFE/545RFE diagnostic booklet adds Quick Learn, Drive Learn, DTC tests, and repair-verification routines, alongside electronic transfer-case diagnosis.

The 45RFE installation warnings explain how excessively long converter-to-driveplate bolts can damage the clutch surface inside the torque converter.

Axle Setup, Alignment, and Circuit References

The C205F front-axle and 9 1/4-inch rear-axle sections cover bearing preload, backlash, and gear-tooth contact patterns, including Trac-Lok service. Front-axle cautions explain how excessive companion-flange tightening can damage the collapsible spacer or bearings.

Suspension information distinguishes the front configurations and supplies caster, camber, and toe specifications. Always verify the designated hoist points and secure the truck on adequately rated jack stands before getting under the chassis to inspect these systems.

Electrical references include Power Distribution, Ground Distribution, Transmission Control System, and All Wheel Antilock Brakes wiring diagrams. The diagnostic booklets add a Transfer Case System Schematic and connector views for tracing circuits between modules and components.

Selected Suspension Torques and Fluid Capacities

For 4WD front-suspension service, the manual specifies 163 N·m (120 ft-lb) for hub/bearing mounting bolts. The lower control-arm front pivot nut and rear pivot bolt are specified at 204 N·m (150 ft-lb).

The capacity chart lists 15.4 L (16.2 qt) for the 4.7L cooling system, including 0.9 L (1.0 qt) for the reservoir. The 9 1/4-inch rear axle has a nominal refill capacity of 2.32 L (4.9 pt); the chart additionally specifies 148 mL (5 oz) of friction modifier for Trac-Lok applications.
