AVC-LAN Circuit Between Radio Receiver and Multi-Display

NAVIGATION: NAVIGATION SYSTEM (for DVD): AVC-LAN Circuit between Radio Receiver and Multi-Display
- AVC-LAN Circuit between Radio Receiver and Multi-Display

DESCRIPTION

The navigation system uses the AVC-LAN to control communication between all of its units. Each unit is connected to the AVC-LAN and communicates by sending and receiving switch signals.

When the AVC-LAN has a +B short or a GND short, communication is cut and the navigation system will not function normally.

(b) Disconnect the R2 or R3 receiver connector.

(c) Measure the resistance of the wire harness side connectors.

Standard resistance:





HINT
*1: for South Korea

*2: Except South Korea

NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.

3. INSPECT INSTRUMENT CLUSTER FINISH PANEL SUB-ASSEMBLY CENTER

(a) Remove the instrument cluster finish panel sub-assembly center.





(b) Measure the resistance of the panel.

Standard resistance:





NG -- REPAIR OR REPLACE INSTRUMENT CLUSTER FINISH PANEL SUB-ASSEMBLY CENTER

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE OR DIAGNOSTIC TROUBLE CODE CHART
