• DaimlerChrysler factory publications for RS/RG minivans, with LHD/RHD body coverage where specified and separate gasoline/diesel control strategies.
• Includes DRBIII-based DTC trees, component locations, connector pinouts, wiring schematics, lab-scope patterns, specifications, torque data, and special service tools.
• Mechanical coverage includes 2.5L/2.8L common-rail turbo diesel service, NV T850 five-speed manual transaxle work, 40TE/41TE electronic-transaxle diagnostics, clutch and driveline service, plus engine cooling, fuel, turbocharger, and emissions systems.

Technical Overview and System Operation

This PDF set is broader than a single body-control book. The 2002 and 2005 Body Diagnostic Procedures volumes explain the BCM, Front Control Module, Integrated Power Module, instrument cluster, PCI bus, automatic and manual temperature control, diesel cabin heater assist, memory seat/mirror functions, adjustable pedals, power sliding doors, power liftgate, RKE/VTSS, wipers, lighting, and related networked modules. The 2005 material adds Occupant Classification System airbag logic, Park Assist, hands-free telecommunications, power windows, and SKREEM-based tire-pressure monitoring.

The PCI bus section is particularly useful for network faults. Chrysler identifies it as a single-wire multiplex network averaging 10,800 bits per second; normal activity pulses from 0 to about 7.5 volts. The diagnostic trees include thresholds for isolating shorts, module-by-module network checks, and DRBIII lab-scope testing rather than relying on a conventional voltmeter. Connector documentation includes the 49-way Front Control Module, BCM C1-C5 connectors, multiple Integrated Power Module connectors, and dedicated power-liftgate and sliding-door module pinouts.

Electrical and Diagnostic Reference

The manual set separates active and stored DTCs, verification tests, input/output checks, component-location views, and connector pinouts from actual service removal procedures. Representative schematics and charts include Airbag System, PCM Communication, Integrated Power Module/Body Control Module Power and Grounds, Power Liftgate System, Power Sliding Door System, and the PCI Bus Lab Scope Pattern. That makes the material especially useful for intermittent network, restraint, HVAC, door-module, and security faults where a generic code list is not enough.

The year-specific books also capture changes in how the same system is diagnosed. For example, the 2002 tire-pressure system uses EVIC-based training and lists low-pressure indicator thresholds of 179 kPa/26 psi ON and 214 kPa/31 psi OFF, plus high-pressure thresholds of 310 kPa/45 psi ON and 276 kPa/40 psi OFF. The 2005 SKREEM-based TPMS automatically learns sensor IDs while driving and uses 193 kPa/28 psi ON and 227 kPa/33 psi OFF for the low-pressure warning. Ambient-temperature sensor tables also give resistance windows such as 17.99–21.81 kΩ at 10°C/50°F.

Powertrain, Transmission, and Diesel Repair Coverage

Gasoline powertrain diagnostics cover the 2.4L and 3.3L/3.8L engines, while the 2005 diesel material covers 2.5L/2.8L four-cylinder common-rail direct-injection engines. The factory service information identifies the 2.5L as the manual-transmission application and the 2.8L as the automatic-transmission application. It specifies a 17.5:1 compression ratio, 6.0 L engine-oil capacity with filter, and cooling-system capacities of 13.8 L without the auxiliary heater or 16.6 L with it. Coverage extends to engine removal, cylinder-head work, piston/liner measurement, timing-belt and tensioner service, turbocharger and exhaust work, common-rail fuel components, cooling, emissions, and electronic control modules.

Transmission material includes 40TE/41TE and EATX/NGC diagnostics, Clutch Volume Index data, DTC event data, factory verification tests, DRBIII Quick Learn, and electronic pinion-factor programming. The Quick Learn section specifies a transmission-oil temperature window of 15–93°C (60–200°F). The diesel service material also contains NV T850 five-speed manual transaxle disassembly/assembly, clutch hydraulic service, Power Transfer Unit and rear driveline module work, with ATF+4 and 80W-90 lubricant specifications and component-specific torque values.

Factory procedures covered include airbag/OCS verification, HVAC cooldown and door recalibration, TPMS/SKREEM training, PCM/TCM diagnosis, transmission Quick Learn and verification, diesel timing setup, cylinder-head and timing-belt repair, turbo/fuel-system repair, clutch service, T850 overhaul, and driveline repair.

A few factory cautions matter during repair. The clockspring must be centered during steering-column service or it can be damaged. On the 2005 NGC PCM, with four 38-pin color-coded connectors, Chrysler specifies Miller #3638 Terminal Removal Pick and #8815 Pinout Box; the text warns that connector or terminal damage can occur if the prescribed tools are not used. For 2.5L/2.8L diesel cylinder-head or timing-belt work, the engine must be positioned at 90° after TDC before certain disassembly, or valve and piston damage can result; the diesel section calls out dedicated VM-series alignment tools, including VM.1051/VM.1083 TDC locating tools and VM.1074 Timing Belt Retainer.

Most Body, Chassis, Powertrain, and Transmission volumes are diagnostic procedure books and refer to the appropriate service information for component removal and repair. The 2003 and 2005 diesel publications are supplements; for non-diesel systems they direct the reader to the corresponding Voyager Service Manual. Within their diesel scope, they provide removal, installation, disassembly, assembly, adjustment, and specification coverage. As a reminder, working with vehicle electrical, restraint, high-pressure diesel fuel, transmission, and A/C systems involves inherent risks; follow the factory safety and isolation procedures before testing or disassembly.
