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 expected to at least 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 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 service-related 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.

For Europe (L.H.D. U.K.) Chart symbols: I : Inspect and clean, repair, adjust, or replace if necessary. R : Replace C : Clean Remarks:

• The ignition and fuel systems are highly important to the emission control system and to efficient engine operation. All inspections and adjustments must be made by an expert repairer, we recommend an Authorized Mazda Repairer.

• After the described period, continue to follow the described maintenance at the recommended intervals.

• Refer below for a description of items marked* in the maintenance chart.

*1: If the vehicle is operated under any of the following conditions, change the engine oil and oil filter every 10,000 km

(6,250 miles) or shorter.

a. Driving in dusty conditions. b. Extended periods of idling or low speed operation.

c. Driving for long period in cold temperatures or driving regularly at short distance only. *2: Also inspect and adjust the power steering and air conditioner drive belts, if installed. *3: If the brakes are used extensively (for example, continuous hard driving or mountain driving) or if the vehicle is

operated in extremely humid climates, change the brake fluid annually.

*4: If the vehicle is operated in very dusty or sandy areas, clean and if necessary, replace the air cleaner element more

often than the recommended intervals.

*5: Replacement of the timing belt is required at every 100,000 km (62,500 miles).

Failure to replace the timing belt may result in damage to the engine.

*6: Replacement of the timing belt is required at every 120,000 km (75,000 miles).

Failure to replace the timing belt may result in damage to the engine.

*7: If the vehicle is operated under any of the following conditions, change the rear differential oil every 45,000 km (27,000

miles).

a. Towing a trailer or using a car - top carrier

b. Driving in dusty, sandy or wet condition

c. Extended periods of idling or low speed operation

Memory function

Sending Continuous Monitoring System Test Results

• These appear when a problem is detected in a monitored system.

1-drive cycle type

• If any problems are detected in the first drive cycle, pending codes will be stored in the PCM memory, as well as DTCs.

• After pending codes are stored, if the PCM determines that the system is normal in any future drive cycle, the PCM deletes the pending codes.

2-drive cycle type

• The code for a failed system is stored in the PCM memory in the first drive cycle. If the problem is not found in the second drive cycle, the PCM determines that the system returned to normal or the problem was mistakenly detected, and deletes the pending code. If the problem is found in the second drive cycle too, the PCM determines that the system has failed, and stores the pending codes, and the DTCs.

• After pending codes are stored, if the PCM determines that the system is normal in any future drive cycle, the PCM deletes the pending codes.

FOREWORD

B6E407018881101

• When the customer reports a vehicle malfunction, check the malfunction indicator light (MIL) indication and diagnostic trouble code (DTC), then diagnose the malfunction according to following flowchart.

— If the DTC exists, diagnose the applicable DTC inspection. (See F2–40 DTC TABLE.) — If the DTC does not exist and the MIL does not illuminate or flash, diagnose the applicable symptom

OBD PENDING TROUBLE CODES

• These appear when a problem is detected in a monitored system. The MIL is illuminated when a problem is detected in two consecutive drive cycles. The code for a failed system is stored in the PCM memory in the first drive cycle. This code is called the pending code. If the problem is not found in the second drive cycle, the PCM judges that the system returned to normal or the problem was mistakenly detected, and deletes the pending code. If the problem is found in the second drive cycle too, the PCM judges that the system has failed, deletes the pending code, illuminates the MIL and stores the DTC.

OBD FREEZE FRAME DATA

• This is the technical data which indicates the engine’s condition at the time of the first malfunction. This data will remain in the memory even if another emission-related DTC is stored, with the exception of Misfire or Fuel System DTCs. Once freeze frame data for a Misfire or Fuel System DTC is stored, it will overwrite any previous data and the freeze frame will not be overwritten again.

OBD PARAMETER IDENTIFICATION (PID) ACCESS

• The PID mode allows access to certain data values, analog and digital inputs and outputs, calculated values and system status information. Since PID values for output devices are PCM internal data values, inspect each device to identify which output devices are malfunctioning.
