DIAGNOSTIC TROUBLE CODE CHART
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.
1. RADIO RECEIVER ASSY (Physical address: 190)
HINT:
*1: Even if no failure is detected, trouble code may be stored depending on the battery condition or
voltage for starting the engine.
*2: It is stored when 180 seconds have passed after the power supply connector is pulled out after the
engine starts.
*3: It may be stored when the engine key is turned 1 minuite after the engine starts.
*4: It may be stored when the engine key is turned again after the engine starts.
*5: When 210 seconds have passed after pulling out the power supply connector of the master compo-
nent with the ignition switch in ACC or ON, this code is stored.
(a) Logical address: 01 (Communication control)
DTCDiagnosis itemDescriptionAction to be taken
22RAM ErrorAbnormal condition of RAM is detected.Replace radio receiver assy.
D6
*1Absence of MasterComponent in which this code is recorded
was disconnected from system or master
component with ignition in ACC or ON.Check harness for power supply system of
radio receiver assy.
Check harness for communication system
of radio receiver assy.
D7
*5Connection check ErrorComponent in which this code is recorded
was disconnected from system or master
component ignition with in ACC or ON.Check harness for power supply of radio
receiver assy.
Check harness for communication system
of radio receiver assy.
D8
*2No Response to Connection CheckComponent shown by sub code is or was
disconnected from system after engine
start.Check harness for power supply system of
component shown by sub code.
Check harness for communication system
of component shown by sub code.
D9
*1Last Mode ErrorAudio or visual component operated before
engine stop is or was disconnected with
ignition switch in ACC or ON.Check harness for power supply system of
component shown by sub code.
Check harness for communication system
of component shown by sub code.
DANo Response to ON/OFF InstructionNo response is identified when changing
mode (audio and visual mode change).
Sound and picture does not change by but-
ton operation.Check harness for power supply system of
component shown by sub code.
Check harness for communication system
of component shown by sub code.
If error occurs again, replace component
shown by sub code.
DB
*1Mode Status ErrorDual alarm is detected.Check harness for power supply of compo-
nent shown by sub code.
Check harness for communication system
of component shown by sub code.
DC
*3Transmission ErrorTransmission to component shown by auxil-
iary code failed.
(Detecting this DTC does not necessarily
mean actual failure.)If same sub code is recorded in other com-
ponent, check harness for power supply and
communication system of all components
shown by code.
(If not, delete DTC and recheck.)
