How to Perform Efficient Diagnosis for an Electrical IncidentINFOID:0000000003531488
WORK FLOW
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 fol-
lowing 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:
• Vehicle vibration
• Heat sensitive
• Freezing
• Water intrusion
• Electrical load
SGI838
STEP DESCRIPTION
STEP 1Get 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/Transaxle 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 2Operate the system, road test if necessary.
Verify the parameter of the incident.
If the problem cannot be duplicated, refer to “Incident Simulation Tests”.
STEP 3Get the proper diagnosis materials together including:
• Power Supply Routing
• 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 4Inspect 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 Lay-
outs.
STEP 5 Repair or replace the incident circuit or component.
STEP 6Operate 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.

WARNING:
• Never get under the vehicle while it is supported only by the jack. Always use safety stands to sup-
port the frame when you have to get under the vehicle.
• Place wheel chocks at both front and back of the wheels on the ground.
CAUTION:
• All applicable State or Provincial (in Canada) laws and local laws regarding the towing operation
must be obeyed.
• It is necessary to use proper towing equipment to avoid possible damage during towing operation.
Towing is in accordance with Towing Procedure Manual at dealer.
• Always attach safety chains before towing.
• When towing, make sure that the transmission, steering system and powertrain are in good order. If
any unit is damaged, dollies must be used.
• Never tow an automatic transmission model from the rear
(i.e., backward) with four wheels on the ground as this may
cause serious and expensive damage to the transmission.
2WD MODELS
INFINITI does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:
• When towing with the front wheels on the ground: Turn the
ignition key to the OFF position and move the transmission
selector lever to N (neutral) position, turn the ignition key to
OFF position and secure the steering wheel in a straight
ahead position with a rope or similar device. Never place the
ignition key in the LOCK position. This will result in damage
to the steering lock mechanism.
