Description
Observe the following precautions to ensure safe and proper servicing. These precautions are not described in each individual section.
OPERATION PROCEDURE
- Connect both battery cables. NOTE: Supply power using jumper cables if battery is discharged.
- Use the Intelligent Key or mechanical key to turn the ignition switch to the "ACC" position. At this time, the steering lock will be released.
- Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
- Perform the necessary repair operation.
- When the repair work is completed, return the ignition switch to the "LOCK" position before connecting the battery cables. (At this time, the steering lock mechanism will engage.)
- Perform a self-diagnosis check of all control units using CONSULT-II.
This volume explains "Removal, Disassembly, Installation, Inspection and Adjustment" and "Trouble Diagnoses".
Relation between Illustrations and Descriptions
The following sample explains the relationship between the part description in an illustration, the part name in the text and the service procedures.

- THE LARGE ILLUSTRATIONS are exploded views (see the following) and contain tightening torques, lubrication points, section number of the PARTS CATALOG (e.g. SEC. 440) and other information necessary to perform repairs. The illustrations should be used in reference to service matters only. When ordering parts, refer to the appropriate PARTS CATALOG. Components shown in an illustration may be identified by a circled number. When this style of illustration is used, the text description of the components will follow the illustration. Refer to «SAE J1930 Terminology List»(ref-239095-S11533881202006072700000) for additional symbol definitions.

Note. Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following instructions before diagnosing.
- Before performing trouble diagnoses, read the "Preliminary Check", the "Symptom Chart" or the "Work Flow".
- After repairs, re-check that the problem has been completely eliminated.
- Refer to Component Parts and Harness Connector Location for the Systems described in each part for identification/location of components and harness connectors.
- Refer to the Circuit Diagram for quick pinpoint check. If you need to check circuit continuity between harness connectors in more detail, such as when a sub-harness is used, refer to Wiring Diagram in each individual section and «HARNESS LAYOUT»(ref-239118-S09569150992006072700000) for identification of harness connectors.
- When checking circuit continuity, ignition switch should be OFF.
- Before checking voltage at connectors, check battery voltage.
- After accomplishing the Diagnostic Procedures and Electrical Components Inspection, make sure that all harness connectors are reconnected as they were.
Scheme 5
- Work and diagnostic procedure Start to diagnose a problem using procedures indicated in enclosed test groups.
- Questions and required results Questions and required results are indicated in bold type in test group. The meaning of are as follows: Battery voltage 11 - 14V or approximately 12V Voltage: Approximately 0V ohms Less than 1V
- Symbol used in illustration Symbols included in illustrations refer to measurements or procedures. Before diagnosing a problem, familiarize yourself with each symbol. Refer to " «CONNECTOR SYMBOLS»(ref-239095-S13969173742006072700000) " and " «KEY TO SYMBOLS SIGNIFYING MEASUREMENTS OR PROCEDURES»(ref-239095-S35842490212006072700000) " below.
- Action items Next action for each test group is indicated based on result of each question. Test group number is shown in the left upper portion of each test group.
