Mitsubishi Eclipse / Eclipse Spyder 2003–2005 Service Manual Set (P/N MSSP-002B-2003)

The volumes work together through cross-references between service procedures, diagnostic checks, specifications, and electrical drawings.

Coverage limits: The referenced Group 36 Parking Brake, Groups 54A/54B Chassis Electrical, and separate 2001 Eclipse/Eclipse Spyder Body Repair Manual are not included. General model tables list F4A52 for some 6G72 automatic applications, but the dedicated automatic-transaxle repair and overhaul chapters cover F4A42/F4A51.

PDF Search, Chapter Bookmarks and File Layout

Search and diagram detail: Service text supports PDF search; some wiring and splice labels do not. All 39 chapter PDFs have embedded bookmarks. The prefaces, indexes, and start file have none, and some cover/index links point to missing files. Fine wiring labels can appear faint at page-fit size and require zooming in the sampled diagrams.

The ZIP contains 48 printable PDFs totaling 3,645 pages, with the four volumes split into chapter and support files. The volume totals above include four 4-page prefaces, four 10-page indexes, and 17 notes pages; the separate 1-page start file is also included in the overall total.

Engine, Transaxle and Spyder Top Service

These selected repair and diagnostic topics show the scope of the material rather than reproduce its full contents. Other covered work includes engine-mount replacement and wheel-balancing diagnosis.

• Engine repair: Step-by-step engine removal and installation, cylinder-head and gasket work, camshaft and oil-seal service, oil-pan repair, timing-belt work, and the 4G64 balance-shaft belt.

• MFI diagnosis: Trouble-code and fail-safe charts, symptom tests, scan-tool data lists, actuator tests, ECM/PCM terminal checks, waveform analysis, and fuel-pressure testing.

• Transaxles: F5M42/F5M51 diagnosis, shift-control service, removal, and internal overhaul; F4A42/F4A51 pressure tests, electronic diagnosis, removal, and overhaul for sport-mode and non-sport-mode systems.

• Brakes and running gear: Axle and suspension repair, wheel alignment, service brakes, ABS and traction-control diagnosis, plus power-steering inspection, bleeding, and pressure tests.

• Body and Spyder top: Doors, window regulators, keyless entry, sunroof, interior/exterior trim, and SRS. Convertible-top procedures cover fit, leaks, drive motors, bows, rails, weatherstrips, and control-module diagnosis.

• Cooling and HVAC: Cooling-system diagnosis, radiator and water-pump service, thermostat inspection, A/C performance testing, refrigerant-leak checks, and heater/evaporator work.

• Electrical references: Component-location drawings, harness routes, and wiring diagrams for power distribution, MFI, INVECS-II 4A/T, ABS/TCL, SRS, and the convertible top.

This material suits technicians familiar with circuit-level diagnosis and equipped with scan tools, electrical test equipment, and the special tools specified for the work.

Engine Overhaul and Control Diagnosis

Internal engine work: Separate 4G64 and 6G72 overhaul chapters address cylinder heads and valves, rocker arms and camshafts, oil pumps, pistons and connecting rods, crankshafts, cylinder blocks, and flywheel or drive-plate inspection. Compression and manifold-vacuum checks support diagnosis before disassembly.

Engine controls: Federal and California emissions applications are identified, together with 6G72 versions with or without Variable Induction Control (VIC). MFI procedures distinguish the manual-transmission ECM from the automatic-transmission PCM and link sensor inputs and actuator commands to connector tests. Injector and oxygen-sensor checks, throttle-position and idle adjustments, and emissions tests use system-specific diagnostic references, including Mitsubishi MUT-II scan tool MB991502.

The engine-electrical section adds generator output-current testing, starter inspection and free-running tests, and ignition-system checks. Tightening specifications, service limits, lubricants, sealants, adjustment data, and electrical test values accompany the applicable procedures.

Transaxle Assemblies and Fault Isolation

Sectional views and internal assembly drawings distinguish the manual and automatic transaxle layouts before overhaul. Automatic overhaul extends to clutch and brake assemblies, the oil pump, valve body, planetary gears, output shaft, and differential.

INVECS-II diagnosis connects fluid-temperature, crankshaft-position, throttle-position, park/neutral, solenoid, and shift-control checks with the relevant circuits. The charts address both stored trouble codes and symptoms that occur without a code.

Tracing Circuits to Connectors and Splices

Group 70 identifies fuses, fusible links, grounds, relays, sensors, control units, solenoids, and inspection terminals. Groups 80A/80B show the engine compartment, engine/transaxle, dash, floor/roof, doors, and model-specific luggage areas.

Splice references S001–S214 connect those location drawings with Group 90 circuit diagrams. This lets a technician follow an electrical fault from a schematic to the corresponding connector or harness branch, rather than rely on the schematic alone.

Connector handling: The electrical precautions explain how backprobing waterproof connectors or forcing probes into terminals can cause corrosion, poor terminal contact, and intermittent faults.

Timing and Service Precautions

The 6G72 timing-belt instructions flag valve-to-piston damage if a camshaft is turned with the first piston at compression top dead center. Observe the manual's SRS, fuel-system, lifting, and refrigerant precautions, and obtain qualified support when the work exceeds your training or equipment.

A Preview of Thermostat and Radiator-Cap Test Values

Thermostat opening temperature is specified at 88 ± 1.5°C for the 4G64 and the 6G72 without VIC, compared with 82 ± 1.5°C for the 6G72 with VIC.

The radiator-cap inspection data distinguish the standard high-pressure valve opening range of 73–103 kPa from the 64 kPa service limit.
