DTC Detection Condition

Trouble Area

01-D5 *1, *4

• A component shown by the sub-code is (was) disconnected from the system when turning the ignition switch on (ACC or IG).

• The communication condition with the device that the code shows cannot be obtained when the engine starts.

01-D8 *2, *4

A component shown by the sub-code is (was) disconnected from the system after engine start.

• Power source circuit of the component shown by the sub-code

• AVC-LAN circuit between the radio and navigation assembly and the component shown by the subcode

01-D9 *1, *4

The device that had functioned before the engine stopped is (was) disconnected from the system when turning the ignition switch is on (ACC or IG).

01-DA *4

• No response is identified when changing mode.

• Detected when sound and image do not change by switch operation.

• Component shown by the sub-code

01-DB *1, *4

A dual alarm is detected.

01-DE *3, *4

A slave device has been disconnected after engine start.

• *1: Even if no fault is present, this trouble code may be stored depending on the battery condition or engine start voltage.

• *2: If the power connector is disconnected after the engine starts, this code is stored after 180 seconds.

• *3: This code may be stored if the engine is started and then the ignition switch is turned to the START position again. (Key type ignition switch only)

• *4: If it is reported that the device does not exist during verification, check the power source circuit and AVC-LAN circuit for the device.

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.

DESCRIPTION

DTC No.

DTC Detection Condition

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 turned on (ACC or IG).

• The master device has (had) been disconnected when this code is stored.

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 on (ACC or IG), 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.
