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;
^ Vehicle vibration
^ Heat sensitive
^ Freezing
^ Water intrusion
^ Electrical load
^ 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.
