ECU Info
This screen looks for problems in the audio-navigation unit. When you initiate this diagnosis, the audio-navigation unit may freeze or delay up to a minute while the diagnosis runs.
NOTE:
Do not try to end this diagnostic by pressing OK or Mem Clear before it finishes, otherwise the system may reboot.
- If V-RAM or D-RAM is NG, replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).
- DVD lid displays the position of the audio-navigation unit lid.
- Program Flash: Displays the version of the navigation software in memory.
- Program on DVD: If displayed, this value represents the version of the navigation software on the navigation DVD.
- DVD version represents the database version on the DVD. You can find this information in either the Setup Screen Version, or in the Diagnostic Screen Version.
- Serial No. should be the same as the serial number found on the underside of the audio-navigation unit. You need this number to obtain the security code from the Interactive Network (iN) system.
- Model: For this model, the field should begin with SZT.
- Mem Clear is used to initialize the memory in the navigation ECU, and to delete the old data program completely. Do not select Mem Clear except when using the Download procedure in Version. Selecting this will clear the customer's settings, personal information, GPS orbital data, and anything else stored in memory.
