Diagnostic Test: Self-Diagnosis Mode
NOTE:
- Check the vehicle battery condition first (see 12 VOLT BATTERY TEST ).
- With good reception, the icon is normally green.
- Make sure the GPS antenna is plugged in.
- Check for any aftermarket accessories or metallic window tinting that may be interfering with the GPS signal.
- Make sure the vehicle is parked outside, away from buildings.
- Refer to GPS INFORMATION for real time satellite reception display.
- Check for aftermarket metallic window tint on the front window and electronic aftermarket accessories (possibly hidden) mounted near the GPS antenna or the audio-navigation unit.
Is there aftermarket metallic window tint or electronic accessories?
YES -Remove the tint or the accessories, and recheck.
NO -Go to step 2.
- Turn the ignition switch to ON (II).
- Go into the System Diagnostic Mode, and use the System Links diagnosis (see SYSTEM DIAGNOSTIC MODE
) to check the GPS antenna.
Is the GPS Ant. icon red?
YES -Check for a kinked, crushed, or disconnected GPS antenna wire. If the icon is still red, replace the GPS antenna (see GPS ANTENNA REMOVAL/INSTALLATION ).
NO -Check that nothing is blocking the GPS antenna located in the dash, and recheck. Substitute a known-good GPS antenna (see GPS ANTENNA REMOVAL/INSTALLATION ), and recheck. If the symptom is gone, replace the GPS antenna (see GPS ANTENNA REMOVAL/INSTALLATION ). If the symptom is still present, replace the original audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).
