Symptom Duplication

WARNING: This page is about a different car, the 2006 Honda Odyssey and 2005 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

If you can duplicate the symptom, comp are it to a "like known-good vehicle." If you can duplicate the symptom in the like known-good vehicle, then it is a characteristic of the system.
A "like known-good vehicle" is another vehicle of the same year and model that has the same software version installed.
When the symptom can be duplicated, follow the self-diagnostic procedures and the appropriate troubleshooting procedures.
When the symptom does not reappear or only reappears intermittently, ask the customer about the conditions when the symptom occurred.
- - Try to establish if outside interference may have been the cause.
- - Try to duplicate the symptom under the same conditions the customer was experiencing.
- - Vibration, temperature extremes, and moisture (dew, humidity) are factors that are difficult to duplicate.
- - Inspect the vehicle for after-market electronic devices (vehicle locators, radar detectors amps, etc.) that may be hidden.
