  Repair procedure 1. Most repair operations begin with an overview illustration. It identifies the components, shows how the parts fit together, and describes visual part inspection. However, only removal/installation procedures that need to be performed methodically have written instructions. 2. Expendable parts, tightening torques, and symbols for oil, grease, and sealant are shown in the overview illustration. In addition, symbols indicating parts requiring the use of special service tools or equivalent are also shown.

  DTC troubleshooting flow (on–board diagnostic) Diagnostic trouble codes (DTCs) are important hints for repairing malfunctions that are difficult to simulate. Perform the specific DTC diagnostic inspection to quickly and accurately diagnose the malfunction. The on–board diagnostic function is used during inspection. When a DTC is shown specifying the cause of a malfunction, continue the diagnostic inspection according to the items indicated by the on–board diagnostic function.
• Page 16
  The diagnostic index lists the symptoms of specific malfunctions. Select the symptoms related or most closely relating to the malfunction. Quick diagnosis chart (If mentioned) The quick diagnosis chart lists diagnosis and inspection procedures to be performed specifically relating to the cause of the malfunction. Symptom troubleshooting Symptom troubleshooting quickly determines the location of the malfunction according to symptom type.
• Page 17
  Using the DTC troubleshooting flow DTC troubleshooting flow shows diagnostic procedures, inspection methods, and proper action to take for each DTC.
• Page 19
  Using the diagnostic index Malfunction symptoms are listed in the diagnostic index under symptom troubleshooting. The exact malfunction symptoms can be selected by following the index. Using the quick diagnosis chart The chart lists the relation between the symptom and the cause of the malfunction. The chart is effective in quickly narrowing down the relation between symptom and cause of the malfunction.

  < Previous Next > 2011 — RX-8 — General Information SERVICE CAUTIONS Injury/damage Prevention Precautions Depending on the vehicle, the cooling fan may operate suddenly even when the ignition switch is turned off. Therefore, keep hands and tools away from the cooling fan even if the cooling fan is not operating to prevent injury to personnel or damage to the cooling fan.
• Page 24
  Special Service Tools Use special service tools or the equivalent when they are required. Malfunction Diagnosis System Use the Mazda Modular Diagnostic System (M-MDS) or equivalent for malfunction diagnosis. Negative Battery Cable Disconnection/Connection Perform the following system initialization after disconnecting the negative battery cable.

  Steering angle sensor (Vehicles with DSC)(See STEERING ANGLE SENSOR INITIALIZATION PROCEDURE.) Power window system (See POWER WINDOW INITIALIZATION PROCEDURE.) Required procedure following negative battery cable disconnection SAS control module Disconnect the negative battery cable and wait for 1 min. or more to allow the back-up power supply to deplete its stored power.

  To determine whether it is necessary to replace the oil after adding the fluorescent dye, refer to the fluorescent dye instruction manual. Not using UV light (black light) 1. Gather some of the leaking oil using an absorbent white tissue. 2.
• Page 27
  Disassembly If the disassembly procedure is complex, requiring many parts to be disassembled, all parts should be marked in a place that will not affect their performance or external appearance, and identified so that reassembly can be performed easily and efficiently. Inspection During Removal, Disassembly When removed, each part should be carefully inspected for malfunction, deformation, damage and other problems.
• Page 28
  Arrangement of Parts All disassembled parts should be carefully arranged for reassembly. Be sure to separate or otherwise identify the parts to be replaced from those that will be reused. Cleaning of Parts All parts to be reused should be carefully and thoroughly cleaned in the appropriate method.
• Page 29
  If removed, the following parts should be replaced with new ones: Oil seals Gaskets O–rings Lock washers Cotter pins Nylon nuts Depending on location: Sealant and gaskets, or both, should be applied to specified locations. When sealant is applied, parts should be installed before sealant hardens to prevent leakage.
• Page 30
  Rubber Parts and Tubing Prevent gasoline or oil from getting on rubber parts or tubing. Hose Clamps When reinstalling, position the hose clamp in the original location on the hose and squeeze the clamp lightly with large pliers to ensure a good fit.
• Page 31
  Torque Formulas When using a torque wrench–SST or equivalent combination, the specified torque must be recalculated due to the extra length that the SST or equivalent adds to the torque wrench. Recalculate the torque by using the following formulas. Choose the formula that applies to you.
• Page 32
  Dynamometer When inspecting and servicing the power train on the dynamometer or speedometer tester, pay attention to the following: Place a fan, preferably a vehicle–speed proportional type, in front of the vehicle. Make sure the vehicle is in a facility with an exhaust gas ventilation system.
• Page 33
  In this case, a DTC will be stored in the memory. Clear the DTC from the memory by following the memory clearing procedure [ABS]/[DSC] in the on-board diagnostic system.

  CAUTION: Do not remove the harness protective tape. Otherwise, the wires could rub against the body, which could result in water penetration and electrical shorting. Connectors Disconnecting connectors When disconnecting connector, grasp the connectors, not the wires.
• Page 38
  Connectors can be disconnected by pressing or pulling the lock lever as shown. Locking connector When locking connectors, listen for a click indicating they are securely locked.
• Page 39
  Inspection When a tester is used to inspect for continuity or measuring voltage, insert the tester probe from the wiring harness side. Inspect the terminals of waterproof connectors from the connector side since they cannot be accessed from the wiring harness side. CAUTION: To prevent damage to the terminal, wrap a thin wire around the tester probe before inserting into terminal.
• Page 40
  Replacement Use the appropriate tools to remove a terminal as shown. When installing a terminal, be sure to insert it until it locks securely. Insert a thin piece of metal from the terminal side of the connector and with the terminal locking tab pressed down, pull the terminal out from the connector.

  Direction of View for Connector The viewing direction of connectors is indicated with a symbol. The figures showing the viewing direction are the same as those used in Wiring Diagrams. The viewing directions are shown in the following three ways: Part-side connector The viewing direction of part-side connectors is from the terminal side.
• Page 44
  Vehicle harness-side connector The viewing direction of vehicle harness-side connectors is from the harness side. Part names are shown only when there are multiple connector drawings.

  Electrical Troubleshooting Tools Jumper wire CAUTION: Do not connect a jumper wire from the power source line to a body ground. This may cause burning or other damage to wiring harnesses or electronic components. A jumper wire is used to create a temporary circuit. Connect the jumper wire between the terminals of a circuit to bypass a switch.
• Page 46
  Ohmmeter CAUTION: Do not connect the ohmmeter to any circuit where voltage is applied. This will damage the ohmmeter. The ohmmeter is used to measure the resistance between two points in a circuit and to inspect for continuity and short circuits. Precautions Before Welding A vehicle has various electrical parts.
• Page 47
