DTC 01-D7 Connection Check Error
DESCRIPTION
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 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

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 preset switch "3" to change to "Detailed
Information Mode".

4 INSPECT RADIO RECEIVER
- Disconnect the radio receiver connectors.
- Measure the resistance according to the value(s) in the
table below.
Standard resistance
*1: 10 Speaker System
5 CHECK HARNESS AND CONNECTOR (RADIO RECEIVER - COMPONENT WHICH HAS STORED
THIS CODE)
HINT: For details of the connectors, refer to the "TERMINALS
OF ECU".
- Referring to the AVC-LAN wiring diagram below, check
the AVC-LAN circuit between the radio receiver and the
component which has stored this code.
- Disconnect all connectors between the radio
receiver and the component which has stored this
code.
- Check for an open or short in the AVC-LAN circuit
between the radio receiver and the component
which has stored this code.
OK:
There is no open or short circuit.
6 REPLACE COMPONENT WHICH HAS STORED THIS CODE
