DETECTABLE LINES AND NON-DETECTABLE LINES
In some wiring diagrams, two kinds of lines, representing wires,
with different weight are used.
lA line with regular weight (wider line) represents a ``detect-
able line for DTC (Diagnostic Trouble Code)''. A ``detectable
line for DTC'' is a circuit in which ECM (Engine Control Mod-
ule) can detect its malfunctions with the on board diagnostic
system.
lA line with less weight (thinner line) represents a ``non-de-
tectable line for DTC''. A ``non-detectable line for DTC'' is a
circuit in which ECM cannot detect its malfunctions with the
on-board diagnostic system.

STEP DESCRIPTION
STEP 1 Get detailed information about the conditions and the environment when the incident occurred.
The following are key pieces of information required to make a good analysis:
WHATVehicle Model, Engine, Transmission and the System (i.e. Radio).
WHENDate, Time of Day, Weather Conditions, Frequency.
WHERERoad Conditions, Altitude and Traffic Situation.
HOWSystem Symptoms, Operating Conditions (Other Components Interaction).
Service History and if any After Market Accessories have been installed.
STEP 2 Operate the system, road test if necessary.
Verify the parameter of the incident.
If the problem can not be duplicated, refer to ``Incident Simulation Tests'' next page.
STEP 3 Get the proper diagnosis materials together including:
POWER SUPPLY ROUTING
System Operation Descriptions
Applicable Service Manual Sections
Check for any Service Bulletin.
Identify where to begin diagnosis based upon your knowledge of the system operation and the customer comments.
STEP 4 Inspect the system for mechanical binding, loose connectors or wiring damage.
Determine which circuits and components are involved and diagnose using the Power Supply Routing and Harness
Layouts.
STEP 5 Repair or replace the incident circuit or component.
STEP 6 Operate the system in all modes. Verify the system works properly under all conditions. Make sure you have not inad-
vertently created a new incident during your diagnosis or repair steps.

Incident Simulation Tests
INTRODUCTION
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 section illustrates ways to simulate the conditions/environment under which the owner experiences
an electrical incident.
The section is broken into the six following topics:
lVehicle vibration
lHeat sensitive
lFreezing
lWater intrusion
lElectrical load
lCold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of
the problem.
VEHICLE VIBRATION
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle
with A/C on). In such a case, you will want to check for a vibration related condition. Refer to the illustra-
tion below.
Connectors & harness
Determine which connectors and wiring harness would affect the electrical system you are inspecting.Gen-
tlyshake each connector and harness while monitoring the system for the incident you are trying to dupli-
cate. 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 ter-
minals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs
intermittently, 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.
Sensors & relays
Gentlyapply 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:
lConnectors not fully seated.
lWiring harness not long enough and is being stressed due
to engine vibrations or rocking.
lWires laying across brackets or moving components.
lLoose, dirty or corroded ground wires.
lWires routed too close to hot components.
To inspect components under the hood, start by verifying the
integrity of ground connections. (Refer to GROUND INSPEC-
TION described later.) First check that the system is properly
grounded. Then check for loose connection bygently 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. Vehicle 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 vibra-
tion. If the wiring runs under seating areas, inspect wire routing
for possible damage or pinching.
HEAT SENSITIVE
The owner's problem 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.
Do not heat components above 60ÉC (140ÉF).If incident
occurs while heating the unit, either replace or properly insulate
the component.
