Mitsubishi Triton L200 1997–2002 Service Manual Set (P/N PWTE96E1)

The chassis change pages and service bulletins supplement the base manual; they are not six separate full manuals. The separate 4M40 publication provides internal engine procedures.

Check the repair scope: The chassis manual covers on-vehicle engine and transmission inspection, adjustment, and major-assembly removal and installation. Full internal overhaul requires the separate publications identified in its service information. Its model tables list 4G63, 4G64, and 4D56 engines, so match the engine code and application before selecting the 4M40 procedures.

The 2002 model table identifies selected K74T versions with V4A51, but there is no dedicated V4A51 repair chapter. The separate electrical wiring and body repair publications listed in the foreword are also outside this set.

PDF Search, Bookmarks and File Contents

Text search and diagram detail: Much of the chassis text is searchable, but several supplements and contents pages are not; the 4M40 volume has no usable text search. All files contain PDF bookmarks, although some cross-file links do not match the supplied folder layout. Small connector numbers and densely arranged diagram labels require zooming in places.

The ZIP contains 36 printable PDFs totaling 1,853 pages. This includes the seven-page cover, foreword, and contents file, 34 section-divider pages, 60 notes pages, and five otherwise blank pages, together with the incorporated revision and service-bulletin pages.

Engine, Drivetrain and Vehicle-System Service

The following highlights are a selection of the contents, rather than a complete table of contents.

• Engine service: Compression and vacuum checks, drive-belt and ignition adjustment, cylinder-head gasket work, timing-system procedures, and engine assembly removal and installation.

• Fuel and boost systems: MPI and 4D56 Step III diagnosis, injection-pump and nozzle service, turbocharger/intercooler checks, and engine electrical testing.

• Transmission and axles: Clutch controls, manual/automatic transmission service, propeller shafts, hubs, drive shafts, freewheel clutch, differential carriers, and rear differential lock.

• Brakes and ABS: Front disc and rear drum service, load-sensing proportioning valve checks, and separate 2WD/4WD ABS troubleshooting.

• Steering and suspension: Manual and power steering gear, power-steering pump and linkage, coil-spring and torsion-bar front suspension, and rear suspension service.

• Body electrical and SRS: Immobilizer registration, ETACS/keyless-entry functions, combination meters, lighting, doors and windows, cab mounting, and airbag diagnosis.

• Heating and A/C: Heater and refrigerant-system service, compressor magnetic-clutch repair, and automatic climate-control diagnosis.

The chassis manual is written for service mechanics; its diagnostic procedures use MUT-II, electrical test equipment, and the specified special tools.

Engine Service and 4M40 Overhaul

The chassis sections provide step-by-step procedures for cylinder-head gasket replacement, timing and balance belts, camshaft and crankshaft oil seals, oil-pan removal, and engine removal and installation. Cooling-system work includes radiator, thermostat, and water-pump service.

The 4M40 publication goes inside the engine: cylinder head and valve train, timing gears and balance shaft, oil pump, pistons and connecting rods, crankshaft, and crankcase. It also covers turbocharger disassembly, injection-nozzle inspection and adjustment, and injection-pump assembly removal and installation.

For 4D56 Step III cylinder-head work, gasket thickness depends on piston projection, which can change after piston or connecting-rod replacement. The timing-belt section warns that an incorrect tensioner-fastener sequence can leave the belt over-tensioned; the oil-pan section warns that unsuitable prying tools can damage the sealing surface and cause oil leaks.

MPI and Electronic Diesel Diagnosis

MPI troubleshooting includes MUT-II trouble-code routines, data-list readings, actuator tests, fail-safe tables, symptom charts, fuel-pressure testing, ECU-terminal checks, injector service, and throttle-body inspection.

The diagnostic charts connect symptoms and codes to circuit measurements, helping distinguish wiring faults from component faults before replacement parts are selected.

The 2002 4D56 Step III material adds electronically controlled injection diagnosis, accelerator-pedal and pump-sensor testing, EGR control, intercooler-fan control, and variable-geometry turbo control for applicable 4WD models.

Charging, starting, and ignition sections add system-specific electrical tests rather than relying solely on general wiring information.

Transmission, Axle and ABS Testing

Automatic-transmission troubleshooting is organized around basic adjustment, road testing, torque-converter stall testing, hydraulic-pressure testing, and the hydraulic circuit before assembly removal.

Axle procedures extend to front hubs and knuckles, drive and inner shafts, differential-carrier disassembly and adjustment, rear axle shafts, differential cases, and the rear differential-lock system.

ABS diagnosis includes code charts, MUT-II actuator tests, wheel-speed-sensor waveform inspection, hydraulic-unit checks, and 4WD G-sensor testing.

Body, SRS and Climate-Control Procedures

Body and electrical: Immobilizer ID registration, keyless-entry secret-code registration, ETACS function adjustment, connector checks, and combination-meter troubleshooting support electrical fault tracing. Body procedures cover power windows, door locks, cab and rear-body mounting, and Club Cab quarter-window glass.

SRS: Post-collision diagnosis and airbag disposal procedures are included. A service bulletin identifies revised SRS-ECU and front-impact-sensor components that are not interchangeable with the earlier versions.

SRS service is specified for authorized Mitsubishi dealer personnel. The precautions address retained system energy, including the minimum 60-second battery-disconnection delay, and the test-equipment requirements for preventing unintended deployment.

Climate control: Heater and A/C procedures include leak diagnosis, refrigerant charging, performance testing, and compressor magnetic-clutch disassembly and air-gap adjustment. The automatic A/C section adds A/C-ECU, sensor, damper-motor, and actuator diagnosis.

Factory Data and Diagnostic Illustrations

Reference material includes lifting and jacking locations, 4WD stream-fording treatment, component-specific torque data, lubricants, sealants, fluid specifications, inspection limits, adjustment data, and electrical test values.

Special-tool listings identify the MB991502 MUT-II subassembly, MB991223 harness set, and MB991613 SRS check harness.

Illustrations include the MPI system diagram, 4D56 Step III control-system diagram, automatic-transmission hydraulic circuit, EGR/vacuum circuits, charging/starting/ignition diagrams, ABS wheel-sensor waveform charts, and exploded component views.

A Preview of Valve and Compression Specifications

For the 4D56, the valve-clearance section specifies a hot-engine check with coolant at 80–90°C and a standard clearance of 0.25 mm, together with the adjustment procedure.

The base 4G63 compression check specifies 1,270 kPa at 250–400 r/min with the throttle fully open; 960 kPa is the minimum limit. The accompanying guidance explains how to interpret compression differences when investigating cylinder, ring, valve, or head-gasket leakage.
