HOW TO USE THIS MANUAL M1001000100110 MAINTENANCE, REPAIR AND SERVICING EXPLANATIONS This manual provides explanations, etc. concerning procedures for the inspection, maintenance, repair and servicing of the subject model. Unless otherwise specified, each service procedure covers all models. Procedures covering specific models are identified by the model codes, or similar designation (engine type, transaxle type, etc.). A description of these designations is covered in this manual under "VEHICLE IDENTIFICATION." ON-VEHICLE SERVICE "ON-VEHICLE SERVICE" are procedures for performing inspections and adjustments of particularly important locations with regard to the construction and for maintenance and servicing, but other inspections (for looseness, play, cracking, damage, etc.) must also be performed. SERVICE PROCEDURES The service steps are arranged in numerical order. Attention must to be paid in performing vehicle service are described in detail in SERVICE POINTS. DEFINITION OF TERMS STANDARD VALUE Indicates the value used as the standard for judging the quality of a part or assembly on inspection or the value to which the part or assembly is corrected and adjusted. It is given by tolerance. LIMIT Shows the standard for judging the quality of a part or assembly on inspection and means the maximum or minimum value within which the part or assembly must be kept functionally or in strength. It is a value established outside the range of standard value. REFERENCE VALUE Indicates the adjustment value prior to starting the work (presented in order to facilitate assembly and adjustment procedures, and so they can be completed in a shorter time). DANGER, WARNING, AND CAUTION DANGER, WARNING, and CAUTION call special attention to a necessary action or to an action that must be avoided. The differences among DANGER, WARNING, and CAUTION are as follows: • If a DANGER is not followed, the result is severe bodily harm or even death. • If a WARNING is not followed, the result could be bodily injury. • If a CAUTION is not followed, the result could be damage to the vehicle, vehicle components or service equipment. TIGHTENING TORQUE INDICATION The tightening torque indicates a median and its tolerance by a unit of N⋅m (in-lb) or N⋅m (ft-lb). For fasteners with no assigned torque value, refer to P.00-30.

TROUBLESHOOTING GUIDELINES TSB Revision GENERAL <BODY AND CHASSIS> 00-6 TROUBLESHOOTING GUIDELINES M1001008800102 VERIFY THE COMPLAINT • Make sure the customer's complaint and the service writer's work order description are understood before starting work. • Make sure the correct operation of the system is understood. Read the service manual description to verify any aspect of normal system operation. • Operate the system to see the symptoms. Look for other symptoms that were not reported by the customer, or on the work order, that may be related to the problem. DETERMINE POSSIBLE CAUSES Compare the confirmed symptoms to the diagnostic symptom indexes to get to the right diagnosis procedure. If the confirmed symptoms can not be found on any symptom index, determine other possible causes. • Analyze the system diagrams and list all possible causes for the problem symptoms. • Rank all these possible causes in order of probability, based on how much of the system they cover, how likely they are to be the cause, and how easy they will be to check. Be sure to take experience into account. Consider the causes of similar problems seen in the past. The list of causes should be ranked in order from general to specific, from most-likely to least-likely, and from easy-to-check to hard-to-check. FIND THE PROBLEM After the symptoms have been confirmed, and probable causes have been identified, the next step is to make step-by-step checks of the suspected system components, junctions, and links in logical order. Use the diagnostic procedures in the service manual whenever possible. Follow these procedures carefully to avoid missing an important step in the diagnosis sequence. It might be the skipped step that leads to the solution of the problem. If the service manual doesn't have step-by-step procedures to help diagnose the problem, come up with a series of checks based on the ranked list of probable causes. Troubleshooting checks should be made in the order that the list of causes was ranked: • general to specific • most-likely to least-likely • easy-to-check to hard-to-check REPAIR THE PROBLEM When the step-by-step troubleshooting checks find a fault, perform the proper repairs. Make sure to fix the root cause of the problem, not just the symptom. Just fixing the symptom, without fixing the root cause, will cause the symptom to eventually return. VERIFY THE REPAIR After repairs are made, recheck the operation of the system to confirm that the problem is eliminated. Make sure to check the system thoroughly. Sometimes new problems are revealed after repairs have been made. HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS M1001000200098 Troubleshooting of electronic control systems for which the scan tool can be used follows the basic outline described below.

SERVICE DATA REFERENCE TABLE Inspection items and normal judgement values have been provided in this chart as reference information. 9. CHECK AT ECU TERMINALS Terminal numbers for the ECU connectors, inspection items and standard values have been provided in this chart as reference information. Terminal Voltage Checks 1. Connect a needle-nosed wire probe to a voltmeter probe. CAUTION Short-circuiting the positive (+) probe between a connector terminal and ground could damage the vehicle wiring, the sensor, the ECU, or all three. Use care to prevent this! 2. Insert the needle-nosed wire probe into each of the ECU connector terminals from the wire side, and measure the voltage while referring to the check chart. NOTE: Measure voltage with the ECU connectors connected. You may find it convenient to pull out the ECU to make it easier to reach the connector terminals. Checks don't have to be carried out in the order given in the chart. 3. If voltage readings differ from normal condition values, check related sensors, actuators, and wiring, then replace or repair. 4. After repair or replacement, recheck with the voltmeter to confirm that the repair has corrected the problem. Terminal Resistance and Continuity Checks 1. Turn the ignition switch to "LOCK" (OFF) position. 2. Disconnect the ECU connector. CAUTION If resistance and continuity checks are performed on the wrong terminals, damage to the vehicle wiring, sensors, ECU, and/or ohmmeter may occur. Use care to prevent this! 3. Measure the resistance and check for continuity between the terminals of the ECU harness-side connector while referring to the check chart. NOTE: Checks don't have to be carried out in the order given in the chart. 4. If the ohmmeter shows any deviation from the Normal Condition value, check the corresponding sensor, actuator and related electrical wiring, then repair or replace. 5. After repair or replacement, recheck with the ohmmeter to confirm that the repair has corrected the problem. 10. INSPECTION PROCEDURES USING AN OSCILLOSCOPE When there are inspection procedures using an oscilloscope, these are listed here. HOW TO USE THE INSPECTION PROCEDURES The causes of many of problems occurring in electric circuitry are generally the connectors, components, the ECU and the harnesses between connectors, in that order. These inspection procedures follow this order. They first try to discover a problem with a connector or a defective component.
