2002-2006 Dodge Sprinter Service & Diagnostic Manuals (P/N 05017397AA)

This factory documentation for the 2002–2006 Dodge Sprinter (VA) combines the service manual with separate Body, Chassis, Powertrain and Transmission diagnostic manuals. Coverage extends from mechanical repair to module, circuit and driveability testing.

• Engine repair: Engine removal, cylinder-head inspection, crankshaft and piston service, timing-chain replacement, compression testing and cylinder leak-down diagnosis.

• Fuel and driveability: Common-rail fuel-system tests, injector classification, no-start diagnosis, boost-control faults, glow-plug circuits and ECM/SKREEM troubleshooting.

• NAG1 transmission: Removal, internal disassembly and assembly, clutch and electrohydraulic-unit service, shift-lever diagnosis and adaptive-control procedures.

• Chassis and brakes: Differential and driveline repair, suspension service, brake bleeding, and Bosch 5.7 ABS, ESP and traction-control diagnosis.

• Body electronics: Airbag and seat belt tensioner tests, instrument-cluster faults, power door locks, remote keyless entry, theft security and rain-sensing wipers.

• Heating and cooling: Automatic Temperature Control diagnosis, Cabin Heater and Heater Booster tests, cooling-system checks, and front and rear A/C service.

• Electrical references: System wiring diagrams, connector pinouts, component locations, sensor charts and repair-verification tests support circuit-level fault tracing.

The procedures suit technicians familiar with electrical diagnosis and mechanical overhaul, with access to a DRBIII scan tool and the specified workshop equipment.

Engine, Fuel Injection and Timing

Compression and cylinder leak-down tests help distinguish leakage through valves, piston rings and sealing surfaces before major engine work. The compression procedures specify adapters 8927 and 9295.

Internal engine coverage includes bearing-shell selection, piston and connecting-rod installation, valve-train work and timing-chain assembly. Cylinder-head inspection covers bolt length and valve setback; machining the head surface or camshaft housing is specifically prohibited.

The timing-cover section warns that misplaced sealant can block pressurized oil passages. Fuel-injection coverage includes injector removal, classification through the DRBIII, and tests for rail-pressure, injector-circuit and boost-control faults.

NAG1 Transmission and Chassis Repair

The transmission section goes inside the assembly, covering holding and driving clutches, freewheels, the oil pump and electrohydraulic control unit. Hydraulic-flow diagrams show individual gear operation and shift transitions.

The diagnostic manual distinguishes active from stored faults and explains adaptive initialization and storage. It also addresses engine driveability problems that can be mistaken for transmission faults.

Rear-axle procedures distinguish single- and dual-rear-wheel assemblies. Brake coverage combines mechanical service with Controller Antilock Brake testing, wheel-speed sensor diagnosis and steering-angle sensor recalibration.

Body System Documentation

The communication sections explain the separate roles of CAN Bus and K-Lines: modules share operating data over CAN, while the DRBIII communicates with individual modules through K-Lines. This distinction helps locate a communication fault before pursuing a component-specific DTC.

Restraint coverage includes seat belt tensioner feedback, crash-deployment reporting and clockspring centering. An incorrectly centered clockspring can be damaged after installation. Door-lock and security testing covers the Sentry Key Remote Entry Module (SKREEM) and Vehicle Theft Security System (VTSS).

Follow the OEM precautions for Supplemental Restraint Systems (SRS) and pressurized A/C components before electrical testing or disassembly.

Cabin Heating and A/C Diagnosis

Automatic Temperature Control tests connect sensor readings, compressor commands and water-cycle valve operation to specific faults. Flame-sensor, refrigerant-pressure sensor and heater-supply checks are supported by diagnostic tables.

The Cabin Heater has its own coolant pump for operation with the engine stopped, unlike the Heater Booster. Supplemental-heater coverage includes diagnosis and component replacement, with an explicit warning against repairing the heater assembly or its internal components.

Wiring Diagrams and Connector References

The wiring sections separate Power Distribution and Bus Communications from Fuel/Ignition System and Transmission Control System circuits. Automatic Temperature Control schematics trace blower controls, sensors and the water-cycle valve.

Connector pinouts and component-location indexes connect those circuits to the actual harness. Evaporator and air-outlet sensor resistance charts provide further diagnostic references.

Selected Compression Limits and Heater Diagnostic Data

These examples represent a small selection of the engine test data and heater diagnostic information in the manuals.

For the 2.7L CDI engine at approximately 80°C (176°F), the compression test specifies a minimum of 18 bar (261 psi) and a permissible cylinder-to-cylinder difference of ±3 bar (±44 psi).

The supplemental-heater controller stores up to five DTCs, replacing the oldest stored code when a new fault is recorded.

PDF Search, Bookmarks and Included Manuals

Search and diagram detail: Text sections support PDF search, but many wiring pages and schematic labels are not searchable. Embedded bookmarks cover all five manuals. Dense schematic labels are best viewed enlarged to read pin numbers and wire codes.

One printable PDF contains 2,300 pages: Service Manual, 1,458; Body diagnostics, 312; Chassis diagnostics, 94; Powertrain diagnostics, 292; and Transmission diagnostics, 144. These totals already include 16 notes pages, 31 blank pages and 10 feedback/address pages, along with the contents and indexes.
