Repair and Diagnosis: Description and Operation
HOW TO USE THIS INFORMATION
Range of Topics
- This information contains procedures for performing all required service operations. The procedures are divided into 5 basic operations:
1 Removal/Installation
2 Disassembly/Assembly
3 Replacement
4 Inspection
5 Adjustment
- Simple operations which can be performed easily just by looking at the vehicle (i.e., removal/installation of parts, jacking, vehicle lifting, cleaning of parts and visual inspection) have been omitted.
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 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 is important or additional information concerning a procedure. See this information when servicing the related part.
Symbols
There are 8 symbols indicating oil, grease, fluids, sealant and special service tool (SST) use. These symbols show application points or use of these materials during service.

Troubleshooting Procedure
Basic flow of troubleshooting
On-Board Diagnosis
- 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.
Engine Tune-Up (Section 01)
- Any necessary adjustments are made after starting the engine.
Basic Inspection
- The basic inspection is performed to quickly narrow down the possible causes of a malfunction regardless of symptoms. Also, basic inspection is performed to locate the area(s) of any malfunction.
Diagnostic Index
- The diagnostic index lists the symptoms of specific malfunctions. Select the symptoms related or most closely relating to the malfunction.
Symptom Troubleshooting
- Symptom troubleshooting quickly determines the location of the malfunction according to symptom type.
Procedures For Use
Using The Basic Inspection
- 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 remarks column.
Using The Diagnostic Index
- The symptoms of the malfunctions are listed in the diagnostic index for symptom troubleshooting.
- The exact malfunction symptoms can be selected by following the index.
Using The Symptom Troubleshooting
- Symptom troubleshooting shows diagnostic procedures, inspection methods, and proper action to take for each trouble symptom.
Text Sequence
- The text sequence is indicated by the arrows shown below.
