INSPECTION PROCEDURE
| 1.CHECK MULTI-DISPLAY POWER SOURCE CIRCUIT |
Refer to the "multi-display power source circuit" (Click here).If the power source circuit is operating normally, proceed to the next step.
| 2.CHECK AVC-LAN CIRCUIT BETWEEN RADIO RECEIVER ASSEMBLY AND GATEWAY ECU |
Refer to the "AVC-LAN circuit between radio receiver assembly and gateway ECU" (Click here).If the AVC-LAN circuit is operating normally, proceed to the next step.
Replace the gateway ECU with a normal one and check if the same problem occurs again.
- OK:
- Same problem does not occur.
