Mazda 3 GS / GT 2006 Service & Repair Manual Collection

System-specific repair articles are paired with wiring diagrams and component-location references. Match each article’s engine, transaxle, and body-style identification to the vehicle before selecting a procedure.

The folders contain different selections of material. The broader body and accessory repair coverage is in the “2004” folder.

Searchable Service Text and Wiring Diagram Files

Text search and diagram detail: Service text and tables are searchable. In the two WIRING PDFs, searches cover headings and figure captions, while the schematic labels are embedded in images. There are no embedded PDF bookmarks. Small labels on dense wiring diagrams require zooming.

The ZIP contains 73 printable English PDFs totaling 3,862 pages. This total includes both copies of the engine-overhaul reference and 122 heading/caption pages within the two WIRING files.

Powertrain Repair, ABS, and Electrical Diagnosis

The following is a selection of covered work, rather than a complete contents list. Additional topics include cruise-control switch inspection and wiper/washer testing.

• Engine repair: Step-by-step teardown, cylinder-head inspection, timing-chain installation, and valve-clearance adjustment for the LF and L3 engines.

• Transaxle overhaul: FN4A-EL automatic and G35M-R manual transaxle procedures, including clutch inspection, differential work, bearing-preload adjustment, and reassembly.

• Brake service and ABS: Disc brake inspection, caliper rebuilding, hydraulic-unit checks, wheel-speed sensor testing, and scan-tool diagnostic procedures.

• Restraint systems: Airbag and pretensioner handling, component replacement, SAS control module configuration, and seat weight sensor calibration.

• Steering and suspension: Electro Hydraulic Power Assist Steering diagnosis, fluid-pressure testing, steering-gear work, strut service, and wheel-bearing replacement.

• Heating and air conditioning: Manual and full-auto control systems, blower and actuator testing, compressor clutch service, and symptom-based troubleshooting.

• Electrical troubleshooting: PCM terminal charts, oscilloscope references, starting and charging tests, wiring diagrams, connector views, and component-location information.

These procedures suit technicians comfortable with circuit diagnosis, precision measurement, and WDS or equivalent diagnostic equipment.

Engine Diagnosis and Internal Repair

Internal engine coverage includes valve-seat repair, piston and crankshaft inspection, and bearing measurements. Separate mechanical service information addresses compression testing and variable valve timing actuator inspection.

The Control System Wiring Diagram [LF, L3] distinguishes California and non-California emission configurations, with further LF ATX and LF MTX/L3 distinctions. Matching those labels to the PCM terminal charts helps technicians select the appropriate circuit checks.

Symptom-troubleshooting charts connect no-start, stalling, rough running, and loss-of-power complaints to electrical and mechanical tests.

Transaxle Components and Overhaul Limits

The FN4A-EL material combines an Automatic Transaxle Cross-Sectional View with the Forward Clutch, 3-4 Clutch Hydraulic Circuit diagram, showing how the internal assemblies relate to hydraulic operation.

The additional automatic-transaxle overhaul article covers the direct clutch, reduction brake, and secondary control valve body. The FN4A-EL torque converter is treated as a sealed unit for inspection rather than internal disassembly.

ABS Diagnosis and Restraint Service

The ABS System Wiring Diagram and HU/CM terminal-voltage tables support pin-level electrical checks. Diagnostic coverage includes DTC retrieval and clearing, PID monitoring, and active command modes.

The sensor inspection section warns that unsuitable resistance testers can damage the ABS wheel-speed sensor’s internal circuit.

Restraint articles distinguish driver-side and passenger-side modules, side airbags, curtain airbags, and pretensioners. They cover deployed and undeployed component disposal, SAS configuration, and the Seat Weight Sensor ReZero Procedure.

Servicing pyrotechnic safety devices carries inherent physical risks. The restraint articles emphasize handling precautions against accidental deployment.

EHPAS and Chassis Service

The EHPAS System Wiring Diagram is paired with control-module terminal references and configuration instructions. Steering-gear coverage extends to rack, pinion, seal, and tie-rod inspection.

Front-suspension instructions also flag the risk of wheel-speed sensor wiring damage when the harness is strained during service.

Climate Controls and Body Equipment

HVAC electrical tests distinguish the full-auto system’s power MOSFET from the manual system’s blower resistor. The earlier-folder HVAC article also covers refrigerant recovery, charging, and performance testing.

Body articles address door and liftgate adjustment, window regulators, glass, mirrors, and trim removal. Security-system material includes transmitter registration and immobilizer component replacement procedures.

A Preview of Thermostat Inspection Data

For LF and L3 engines, the thermostat inspection specifies initial opening at 80–84°C (176–183°F). It lists 97°C (207°F) for full opening and a minimum full-open lift of 8.0 mm (0.31 in).
