DIAGNOSIS CODE LIST
TermsMeaning
Physical addressThree-digit code (shown in hexadecimal) which is given to each component com-
prising the AVC-LAN.
Corresponding to the function, individual symbols are specified.
Logical addressTwo-digit code (shown in hexadecimal) which is given to each function comprising
the inner system of the AVC-LAN.
(a) Physical address 190: Radio receiver assembly
HINT:
*1: Even if no failure is detected, it may be stored depending on the battery condition or voltage for
starting an engine.
*2: It is stored when 180 sec. has passed after the power supply connector is pulled out after engine
start.
*3: It may be stored when the engine key is turned 1 min. again after engine start.
*4: It may be stored when the engine key is turned again after engine start.
*5: When 210 sec. has passed after pulling out the power supply connector of the master component
with the ignition switch in ACC or ON, this code is stored.
(1) Logical address: 01 (Communication control)
DTCDiagnosis itemDiagnosis contentCountermeasure and inspected parts
D6
*1Absence of MasterComponent in which this code is recorded
has been disconnected from system with
ignition in ACC or ON. Or, when this code
was recorded, multi-display assembly was
disconnected.Check harness for power supply system of
multi-display.
Check harness for communication system
of multi-display.
Check harness for power supply system of
radio and player.
Check harness for communication system
of radio and player.
D8
*2No Response to Connection CheckComponent shown by auxiliary code is or
had been disconnected from system after
engine is start.
D9Check harness for power supply system of
component shown by auxiliary code.
Check harness for communication system
of component shown by auxiliary code.
D9
*1Last Mode ErrorComponent operated (sounds and/or
images were provided) before engine stop is
or has been disconnected with ignition
switch in ACC or ON.Check harness for power supply system of
component shown by auxiliary code.

of component shown by auxiliary code.
DANo Response to ON/OFF InstructionNo response is identified when changing
mode (audio and visual mode change).
Detected when sound and picture does not
change by button operation.Check harness for power supply system of
component shown by auxiliary code.
Check harness for communication system
of component shown by auxiliary code.
If error occurs again, replace component
shown by auxiliary code.

*1Mode Status ErrorDual alarm is detected.Check harness for power supply of compo-
nent shown by auxiliary code.
Check harness for communication system
of component shown by auxiliary code.

*3Transmission ErrorTransmission to component shown by auxil-
iary code has been failed.
(Detecting this DTC does not necessarily
mean actual failure.)If same auxiliary code is recorded in order
component, check harness for power supply
and communication system of all compo-
nents shown by code.
