•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 6.
No
Go to the next step.
2
INSPECT GPS ANTENNA GROUND CIRCUIT FOR OPEN CIRCUIT
•  GPS antenna connector is disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
―  Multi information display terminal 3B
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 6.
3
INSPECT MULTI INFORMATION DISPLAY CONNECTOR AND TERMINALS
•  Disconnect the multi information display connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 6.
No
Go to the next step.
4
INSPECT GPS ANTENNA SIGNAL CIRCUIT FOR OPEN CIRCUIT
•  GPS antenna and multi information display connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  Multi information display terminal 3A—GPS antenna terminal A
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 6.
5
VERIFY GPS ANTENNA MALFUNCTION
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from multi information display using the M-MDS.
•  Switch the ignition to ACC.
•  Perform the “DTC INSPECTION”.
•  Is the same DTC present?
Yes
Replace the GPS antenna, then go to the next step.
(See GPS ANTENNA REMOVAL/INSTALLATION.)
No
Go to Step 7.
6
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from multi information display using the M-MDS.
•  Switch the ignition to ACC.
•  Perform the “DTC INSPECTION”.
•  Is the same DTC present?
Yes
Replace the multi information display, then go to the next step.
(See MULTI INFORMATION DISPLAY REMOVAL/INSTALLATION.)
No
Go to the next step.
7
VERIFY THAT NO OTHER DTCs ARE PRESENT
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [INFORMATION DISPLAY/MULTI INFORMATION DISPLAY].)
