Introduction

Sometimes the symptom is not present when the vehicle is brought in for service. Therefore, it is necessary to simulate the conditions and environment when the incident occurred. Otherwise, only a No Trouble Found Diagnosis may be found. The following tests illustrate ways to simulate the conditions/environment under which the owner experiences an electrical incident.
The tests are broken into the six following topics:
^ Vehicle vibration
^ Heat sensitive
^ Freezing
^ Water intrusion
^ Electrical load
^ Cold or hot start up
