Description

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.

Scheme 1

Scheme 2

1. THE LARGE ILLUSTRATIONS are exploded views (see the following) and contain tightening torques, lubrication points, service number of the PARTS INFORMATION (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 component information. 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 this information for additional symbol definitions.

Scheme 3

Note. Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following instructions before diagnosing.

1. Before performing trouble diagnoses, read the "Work Flow" in each information area.
2. After repairs, re-check that the problem has been completely eliminated.
3. Refer to appropriate component and connector location information for the Systems described in each area of this service information for identification/location of components and harness connectors.
4. When checking circuit continuity, ignition switch should be OFF.
5. Refer to the appropriate Wiring Diagrams information 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 appropriate Wiring Diagrams information in each individual article and «HARNESS LAYOUT»(ref-368780-S04854898752010081300000) in Electrrical Power Information for identification of harness connectors.
6. Before checking voltage at connectors, check battery voltage.
7. After accomplishing the Diagnosis Procedures and Electrical Components Inspection, make sure that all harness connectors are reconnected as they were.

Scheme 4

1. Test group number and test group title Test group number and test group title are shown in the upper portion of each test group.
2. Work and diagnosis procedure Start to diagnose a problem using procedures indicated in enclosed test groups.
3. Questions and results Questions and required results are indicated in test group.
4. Action Next action for each test group is indicated based on result of each question.

ABBREVIATION CHART

This vehicle has both new standard based on ISO* and previous standard bolts/nuts. There are some differences between these two types of bolts/nuts; shape of the head, grade of strength, hexagonal width across flats and the standard tightening torque.

1. For guidance in discriminating, refer to " «TIGHTENING TORQUE TABLE (NEW STANDARD INCLUDED)»(ref-368779-S23099909782010081300000) ".
2. The new standard machine screws and tapping screws have a head of ISO standard Torx recess.
3. If the tightening torque is not described in the description or figure, refer to " «TIGHTENING TORQUE TABLE (NEW STANDARD INCLUDED)»(ref-368779-S23099909782010081300000) ". *ISO: International Organization for Standardization

Observe the following precautions to ensure safe and proper servicing. These precautions are not described in each individual article.

OPERATION PROCEDURE

1. Connect both battery cables. NOTE: Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position. At this time, the steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released with both battery cables disconnected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn the push-button ignition switch from ACC position to ON position, then to LOCK position. The steering wheel will lock when the push-button ignition switch is turned to LOCK position.
6. Perform self-diagnosis check of all control units using CONSULT-III.

Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The following list illustrates ways to simulate the conditions/environment under which the owner experiences an electrical incident.

The following information is broken into the six topics

1. Vehicle vibration
2. Heat sensitive
3. Freezing
4. Water intrusion
5. Electrical load
6. Cold or hot start up

Get a thorough description of the incident from the customer. It is important for simulating the conditions of the problem.

1. In general, testing electrical circuits is an easy task if it is approached in a logical and organized method. Before beginning it is important to have all available information on the system to be tested. Also, get a thorough understanding of system operation. Then you will be able to use the appropriate equipment and follow the correct test procedure.
2. You may have to simulate vehicle vibrations while testing electrical components. Gently shake the wiring harness or electrical component to do this. CIRCUIT DESCRIPTION CHART OPEN A circuit is open when there is no continuity through a portion of the circuit. SHORT There are two types of shorts. SHORT CIRCUIT When a circuit contacts another circuit and causes the normal resistance to change. SHORT TO GROUND When a circuit contacts a ground source and grounds the circuit. NOTE: Refer to " «HOW TO CHECK TERMINAL»(ref-368779-S02261837122010081300000) " to probe or check terminal.
