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.
