Performing Efficient Electrical Circuit Diagnosis and Troubleshooting
STEPDESCRIPTION
Step 1 Obtain detailed information about the conditions and the environment when the electrical
incident occurred.
Step 2 Operate the affected system, road test the vehicle if necessary.
Verify the parameter of the incident.
If the problem cannot be duplicated, refer to “Electrical Failure Simulation Tests”.
Step 3 Gather the proper diagnostic material including the following:
•
Electrical Power Supply Routing Diagram
• System Operation Descriptions
• Applicable Service Manual Sections
• Check for any Service Bulletins
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 Electrical
Power Supply Routing Diagram and Harness Layouts.
Step 5 Repair the circuit or replace the component as necessary.
Step 6 Operate the system in all modes. Verify the system functions properly under all conditions.
Confirm you have not inadvertently created an additional new incident during your
diagnosis or repair steps.
Electrical Circuit Simulation Tests
Often 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 illustrates
tests to simulate the conditions/environment under which the owner experiences an electrical incident.
The tests are broken into the seven following topics:
•
Vehicle Vibration Test
• Heat Sensitive Test
• Freezing Test
• Water Intrusion Test
• Electrical Load Test
• Cold or Hot Start Up Test
• Voltage Drop Test
NOTE :
Always get a thorough description of the incident from the customer. It is important for simulating the conditions of
the problem.
Vehicle Vibration Test
The problem may occur or become worse while driving on a rough road or when the engine is vibrating (idle with A/C
on). In such a case, check for a vibration related condition. Refer to the following vehicle areas:
Connectors & Harness
• 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.
NOTE :
Connectors can be exposed to moisture. It is possible for a thin film of corrosion to form on the connector terminals.
A visual inspection may not reveal this without disconnecting the connector. If the problem occurs intermittently, per-
haps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the terminals on related
connectors in the system.

Downloaded from www.Manualslib.com manuals search engine Sensors & Relays
•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 the ground connections (See Ground
Inspection described later). First, verify that the system is properly grounded. Then check for any loose connec-
tions 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. Vehicle
vibration can aggravate a harness which is routed along a bracket or near a mounting screw.
• 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 Sensitivity Test
The customer’s concern may occur during hot weather or after the vehicle 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°F).
If the incident occurs while heat testing the component, replace or properly insulate the component as needed.
Freezing Test
The customer may indicate the incident goes away after the vehicle warms up (winter time). The cause could be
related to water freezing somewhere in the wiring/electrical system. There are two methods to check for this:
•The first method is to arrange for the owner to leave the vehicle overnight. Make sure it will get cold enough to
duplicate the complaint. Leave the vehicle parked outside overnight. In the morning, do a quick and thorough
diagnosis of those electrical components which could be affected.
• The second method is to put the suspect component into a freezer long enough for any water to freeze. Rein-
stall the part into the vehicle and check for a reoccurrence of the incident. If it occurs, repair or replace the
component as needed.
Water Intrusion Test
The incident may occur only during high humidity or in rainy/snowy weather. In such cases the incident could be
caused by water intrusion on an electrical part. This can be simulated by soaking the car or running it through a car
wash.
Electrical Load Test
The incident may be electrical load sensitive. Perform diagnosis with all accessories (including A/C, rear window
defogger, radio, fog lamps) turned on.
Cold or Hot Starting Test
On some occasions an electrical incident may occur only when the vehicle is started cold, or it may occur when the
vehicle is restarted hot shortly after being turned off. In these cases you may have to keep the vehicle overnight to
make a proper diagnosis.
