Navi ECU
This screen looks for problems in the navigation unit. When you initiate this diagnosis, the navigation unit may 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, then replace the navigation unit.
- If "GPS" indicates "NG (ANT)," then check the entire GPS antenna wire from the navigation unit to the antenna. If the wire is crushed or damaged, try a known good antenna. If this diagnostic reads OK, then order a new GPS antenna. If the diagnostic still reads NG (ANT), then replace the navigation unit.
- "DVD ROM" 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 navigation unit. You need this number to obtain the security code from the Interactive Network (iN) system.
- The Mem Clr is for factory use and should not be used unless instructed by the factory.
Selecting this will clear the client's settings, personal information, GPS orbital data, and anything else stored in memory.
