Service Procedure

Inspection, adjustment

• Inspection and adjustment procedures are divided into steps. Important points regarding the location and contents of the procedures are explained in detail and shown in the illustrations.

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.

3. Procedure steps are numbered and the part that is the main point of that procedure is shown in the illustration with the corresponding number. Occasionally, there are important points or additional information concerning a procedure. Refer to this information when servicing the related part.

Troubleshooting Procedure

Basic flow of troubleshooting

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.

Diagnostic index

• 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.

Procedures for Use

Using the basic inspection (transmission/transaxle)

• Perform the basic inspection procedure before symptom troubleshooting.

• Perform each step in the order shown.

• The reference column lists the location of the detailed procedure for each basic inspection.

• Although inspections and adjustments are performed according to the reference column procedures, if the cause of the malfunction is discovered during basic inspection, continue the procedures as indicated in the action column.

Using the DTC troubleshooting flow

• DTC troubleshooting flow shows diagnostic procedures, inspection methods, and proper action to take for each DTC.

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.

• Correctly verify the malfunction symptom according to “DESCRIPTION”.

Using the quick diagnosis chart

• The related malfunction cause can be understood.

• The relation between the malfunction symptom and cause is indicated.

• The relation between the malfunction symptom and cause can be detected quickly, and if multiple malfunction symptoms occur, the area which is the common cause among the multiple malfunctions can be specified.

• The effective inspection procedure for the malfunction cause specified from the malfunction symptoms can be selected using the inspection procedure chart.
