Trouble Area |
01-D6
*1 |
When either of the following conditions is met:
- The component which has stored the code has
(had) been disconnected when the ignition switch is
in the ACC or ON position.
- The master device has (had) been disconnected
when this code is stored
|
- Radio and navigation assembly power source
circuit
- Power source circuit of the component which has
stored this code
- AVC-LAN circuit between the radio and navigation
assembly and the component which has stored this
code
- Component which has stored this code
- Radio and navigation assembly
|
01-D7
*2 |
When either of the following conditions is met:
- The component which has stored the code has
(had) been disconnected after the engine starts
(started).
- The master device has (had) been disconnected
when this code is (was) stored
|
HINT:
- *1: Even if no fault is present, this trouble code may be stored
depending on the battery condition or
engine start voltage.
- *2: When 210 seconds have elapsed after disconnecting the power
supply connector of the master
component with the ignition switch is in the ACC or ON position, this code
is stored.
NOTICE:
- Before starting troubleshooting, be sure to clear DTCs to erase
codes stored due to the
reasons described in the HINT above. Then, check for DTCs and troubleshoot
according to the
output DTCs.
- The radio and navigation assembly is the master unit.
- Be sure to clear and recheck DTCs after the inspection is
completed to confirm that no DTCs
are output.
INSPECTION PROCEDURE
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 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
3 CHECK POWER SOURCE CIRCUIT OF COMPONENT WHICH HAS STORED THIS CODE
- Inspect the power source circuit of the component which
has stored this code.
If the power source circuit is operating normally, proceed
to the next step
Component Table:

4 CHECK 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
5 CHECK HARNESS AND CONNECTOR
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.
OK:
There is no open or short circuit.
6 REPLACE COMPONENT WHICH HAS STORED THIS CODE
- Replace the component which has stored this code with
a normal one and check if the same problem occurs
again.
OK:
Same problem does not occur.
