NOTICE: Be sure to read DESCRIPTION before performing the following procedures.
1 CHECK RADIO AND NAVIGATION ASSEMBLY POWER SOURCE CIRCUIT
Refer to the radio and navigation assembly power source circuit.
If the power source circuit is operating normally, proceed to the next step
2 INSPECT RADIO AND NAVIGATION ASSEMBLY
- Disconnect the radio and navigation assembly connectors.
- Measure the resistance according to the value(s) in the table below.
Standard resistance
3 IDENTIFY THE COMPONENT WHICH HAS STORED THIS CODE
- Enter the diagnostic mode.
- Press the "LAN Mon" switch to change to "LAN Monitor" mode.
- Identify the component which has stored this code.
Component Table:
HINT: "NAVI" is the component which has stored this code in the example shown in the illustration.
4 CHECK HARNESS AND CONNECT
HINT: For details of the connectors, refer to "TERMINALS OF ECU".
- Referring to the AVC-LAN wiring diagram below, check the AVC-LAN circuit between the radio and navigation assembly and the component which has stored this code.
- Disconnect all connectors between the radio and navigation assembly and the component which has stored this code.
- Check for an open or short in the AVC-LAN circuit between the radio and navigation assembly and the component which has stored this code.
