2009 Honda CR-V EX, 2.4 RE3SECTION Symptom Duplication
WARNING: This page is about a different car, the 2011 Honda CR-V and 2010 Honda CR-V. However, it is still accessible from the selected car via links, so may be relevant.
- When the symptom can be duplicated, verify that it is not a characteristic of the system. Review the navigation system service information and compare it to a known-good vehicle (with the same software and database), under the same conditions. If the symptom is not the same as the known-good vehicle, 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.
- Always ask the customer to demonstrate the problem.
- Ask the customer if they remember the time and date when they had the issue. You may be able to find the DTC stored in the hard error history.
- Try to establish possible user error or misunderstanding of the system.
- Try to establish if outside interference may have been the cause.
- Try to duplicate the symptom under the same conditions the customer experienced.
- Vibration, temperature extremes, and moisture (dew, humidity) are factors that are difficult to duplicate.
- Inspect the vehicle for after-market electronic devices (vehicle locators, amps, radar detectors, etc.) that may be hidden.
NOTE:
When troubleshooting navigation system problems, ensure that the known-good vehicle is the same software version year and model as the vehicle being serviced. Mixing incompatible navigation DVDs or other system components can delay the troubleshooting process by creating symptoms or causing effects unrelated to the original problem.
