2000 Toyota Celica ZZT230 & ZZT231 OEM Repair Manual Set (P/N RM744U1, RM744U2)

Volume 1 supplies the diagnostic routines, service specifications, and preparation lists used alongside the repair procedures in Volume 2. Together, they cover the 1ZZ-FE and 2ZZ-GE engine configurations.

Internal automatic-transaxle overhaul procedures referenced in the diagnostic charts require the separate U240E manual RM740U or U341E manual RM735U; those publications are not included. System-specific wiring diagrams are included, but the separate vehicle Electrical Wiring Diagram publication EWD399U is not part of this set.

Two Volumes in One Printable PDF

Search, volume access, and diagram detail: PDF text search is not available. Two embedded bookmarks open the volume beginnings; individual chapters are not bookmarked. Small connector numbers and wire-color codes in dense ABS circuit diagrams require zooming.

One printable PDF contains 1,972 pages total, including two covers, six foreword/caution/overview pages, and 44 blank or MEMO pages. These pages are already included in the publication totals above.

Engine, Transaxle, and Vehicle-System Service

• Engine mechanical: Step-by-step procedures for engine removal, timing-chain installation, cylinder-head disassembly, cylinder-block inspection, and reassembly.

• Fuel and engine controls: Fuel-pressure testing, injector inspection, EVAP checks, and VVT/VVTL circuit diagnosis with related electrical specifications.

• Transaxles and clutch: C56 and C60 disassembly and inspection, clutch service, plus U240E and U341E diagnosis, testing, and on-vehicle component replacement.

• Brakes and chassis: ABS with Electronic Brake Force Distribution, brake bleeding, caliper service, wheel alignment, suspension repair, and power-steering inspection.

• Electrical and restraints: Engine, SRS, cruise-control, and Body Control System troubleshooting, supported by wiring diagrams, connector views, and diagnostic charts.

• Cooling and air conditioning: Coolant replacement, water-pump service, thermostat testing, radiator repair, and refrigerant-system diagnosis.

Toyota identifies this documentation as intended for technicians with specialized skills and certifications, using the specified tools and equipment.

Engine Repair and Service Preparation

The engine chapters separate the procedures for the two engine configurations, including valve adjustment, camshaft inspection, bearing selection, and piston-clearance checks. Illustrated component layouts identify assembly relationships, non-reusable parts, and fastener specifications in N·m and ft-lbf or in-lbf.

Preparation lists identify special service tools, measuring equipment, lubricants, and service materials before work begins. The lubrication table recommends SAE 5W-30 for fuel economy and cold-weather starting. Maintenance procedures are included; market-specific maintenance schedules are referred to the owner’s manual supplement.

Fault Tracing and Electrical Reference

Customer problem-analysis sheets, symptom simulation tests, and problem-symptom tables help technicians connect an intermittent complaint to the relevant circuit checks before selecting a repair. Engine diagnosis includes trouble-code charts, freeze-frame data, ECM terminal checks, and active tests.

MAF-meter and shift-solenoid wiring diagrams sit alongside ABS wheel-speed-sensor and SRS D-squib circuits. Connector terminal views and diagnostic flowcharts connect these illustrations to the associated inspections.

Manual and Automatic Transaxle Work

The manual-transaxle chapters extend into input and output shafts, synchronizers, differential inspection, and bearing-preload adjustment. The automatic sections include hydraulic and stall tests, shift-solenoid checks, valve-body service, and transaxle removal and installation.

These sections distinguish diagnosis and accessible component service from the internal overhaul work assigned to the separate automatic-transaxle publications.

Chassis, Body, and Air Conditioning

Chassis coverage includes wheel bearings, drive shafts, front and rear brake assemblies, and power-steering pump and gear service. Body electrical sections address lighting, windows, door locks, and audio-system troubleshooting; body procedures cover doors, glazing, seats, and instrument-panel removal.

Air-conditioning content includes manifold-gauge diagnosis, compressor and magnetic-clutch service, and heater-control inspection. Starting and charging chapters provide starter and generator inspection and repair procedures.

The SRS precautions address stored backup power and unintended deployment during service. Steering-wheel installation notes warn that incorrect spiral-cable centering can cause cable disconnection; the manufacturer’s precautions remain essential for SRS, ECU wiring, and pressurized-system work.

Sample Valve-Clearance and Chassis Torque Data

The maintenance tables distinguish front suspension member-to-body bolts by position: Bolt B is specified at 157 N·m (116 ft-lbf), rather than one universal torque for every mounting bolt.

Cold exhaust-valve clearance is 0.25–0.35 mm for the 1ZZ-FE and 0.35–0.45 mm for the 2ZZ-GE. The engine chapters pair these engine-specific ranges with valve-adjustment and shim-selection instructions.
