WARNING Servicing a vehicle can be dangerous If you have not received service-related training, the risks of injury, property damage, and failure of servicing increase The recommended servicing procedures for the vehicle in this workshop manual were developed with Mazda-trained technicians in mind This manual may be useful to non-Mazda trained technicians, but a technician with our service-related training and experience will be at less risk when performing service operations However, all users of this manual are excepted at least to know general safety procedures This manual contains “Warnings” and “Cautions” applicable to risks not normally encountered in a general technician’s experience They should be followed to reduce the risk of injury and the risk that improper service or repair may damage the vehicle or render it unsafe It is also important to understand that the “Warnings” and “Cautions” are not exhaustive It is impossible to warn of all the hazardous consequences that might result from failure to follow the procedures The procedures recommended and described in this manual are effective methods of performing service and repair Some require tools specifically designed for a specific purpose Persons using procedures and tools which are not recommended by Mazda Motor Corporation must satisfy themselves thoroughly that neither personal safety nor safety of the vehicle will be jeopardized The contents of this manual, including drawings and specifications, are the latest available at the time of printing, and Mazda Motor Corporation reserves the right to change the vehicle designs and alter the contents of this manual without notice and without incurring obligation Parts should be replaced with genuine Mazda replacement parts or with parts which match the quality of genuine Mazda replacement parts Persons using replacement parts of lesser quality than that of genuine Mazda replacement parts must satisfy themselves thoroughly that neither personal safety nor safety of the vehicle will be jeopardized Mazda Motor Corporation is not responsible for any problems which may arise from the use of this manual The cause of such problems includes but is not limited to insufficient servicerelated training, use of improper tools, use of replacement parts of lesser quality than that of genuine Mazda replacement parts, or not being aware of any revision of this manual Form No.5593-1A-03K Mazda3 CONTENTS SECTION TITLE PREVIOUS NEW GI (GENERAL INFORMATION) Wiring Diagram W (ELECTRICAL WIRING SCHEMATIC) FB (FUSE BLOCK) JB GENERAL
