HOW TO FOLLOW TROUBLE DIAGNOSES
HOW TO FOLLOW TROUBLE DIAGNOSES
DescriptionINFOID:0000000003852763
NOTICE:
Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following
instructions before diagnosing.
 Before performing trouble diagnoses, read the “Work Flow” in each section.
 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 section for
identification/location of components and harness connectors.
 When checking circuit continuity, ignition switch should be OFF.
 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-har-
ness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG section for identi-
fication of harness connectors.
 Before checking voltage at connectors, check battery voltage.
 After accomplishing the Diagnosis Procedures and Electrical Components Inspection, make sure that all
harness connectors are reconnected as they were.

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.

Connector SymbolsINFOID:0000000003852766
Most of connector symbols in wiring diagrams are shown from the terminal side.
 Connector symbols shown from the terminal side are enclosed by
a single line and followed by the direction mark.
 Connector symbols shown from the harness side are enclosed by
a double line and followed by the direction mark.
 Certain systems and components, especially those related to
OBD, may use a new style slide-locking type harness connector.
For description and how to disconnect, refer to PG section,
“Description”, “HARNESS CONNECTOR”.
 Male and female terminals
Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.

3Number of fusible link/
fuse This means the number of fusible link or fuse location.
4 Fuse  “/” means the fuse.
5Current rating of fus-
ible link/fuse This means the current rating of the fusible link or fuse.
6 Optional splice  The open circle shows that the splice is optional depending on vehicle application.
7 Connector number The letter shows which harness the connector is located in.
 Example “M”: main harness. For detail and to locate the connector, refer to, .PG-83, "
How
To Read Harness Layout",PG-85, "Main Harness"
8Splice
 The shaded circle “ ” means the splice.

HOW TO READ WIRING DIAGRAMS
 ignition switch is “OFF”,
 doors, hood and trunk lid/back door are closed,
 pedals are not depressed, and
 parking brake is released.
MULTIPLE SWITCH
The continuity of multiple switch is described in two ways as shown below.
 The switch chart is used in schematic diagrams.
 The switch diagram is used in wiring diagrams.

< BASIC INSPECTION >
SERVICE INFORMATION FOR ELECTRICAL INCIDENT
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently
shake each connector and harness while monitoring the system for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
Hint
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter-
mittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the
terminals on related connectors in the system.
Sensor & Relay
Gently apply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
Engine Compartment
There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the
things to check for are:
 Connectors not fully seated.
 Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
 Wires laying across brackets or moving components.
 Loose, dirty or corroded ground wires.
 Wires routed too close to hot components.
To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the
wiring for continuity.
Behind the Instrument Panel
An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehi-
cle vibration can aggravate a harness which is routed along a bracket or near a screw.
Under Seating Areas
An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides)
during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or
pinching.
HEAT SENSITIVE
 The customer's concern may occur during hot weather or after car
has sat for a short time. In such cases you will want to check for a
heat sensitive condition.
 To determine if an electrical component is heat sensitive, heat the
component with a heat gun or equivalent.
CAUTION:
Do not heat components above 60°C (140°).
 If incident occurs while heating the unit, either replace or properly
insulate the component.

The DDL1 and DDL2 circuits from DLC pins 12, 13, 14 and 15 may be connected to more than one system. A
short in a DDL circuit connected to a control unit in one system may affect CONSULT-III access to other sys-
tems.
