AVC-LAN CIRCUIT (NAVIGATION ECU - MULTI-DISPLA Y)
CIRCUIT DESCRIPTION
Each unit of the navigation system connected to AVC-LAN (communication bus) communicates by transfer-
ring the signals from each switch.
When +B short and GND short occur in this AVC-LAN, navigation system will not function normally as com-
munication is discontinued.
In AVC-LAN, multi-display becomes the communication master, and the radio receiver assy has enough
resistance necessary for transmitting the communication.

O2S TEST RESULT Screen 05-22

O2S TEST RESULT
1. INTRODUCTION
The O2S TEST RESULT refers to the results of the engine con-
trol module (ECM) when it monitors the oxygen sensor (O2S),
and it can be read using the hand-held tester or the generic
OBD II scan tool. Based on this, you can find the O2S's condi-
tions.
The ECM monitors the O2S for various data. You can read the
monitor result (TEST DATA) of each monitor item using the O2S
TEST RESULT. However, the output value of the TEST DATA
is the latest ºsnapshotº value that is taken after monitoring and
therefore it is not dynamic.
In this repair manual, the description of the O2S TEST RESULT
(for O2S related DTCs) are written in a table.
This table consists of 5 items:
(1) TEST ID (a code applied to each TEST DATA)
(2) Description of TEST DATA
(3) Conversion Factor (When conversion factor has a
value written in the table, multiply the TEST DATA
value appearing on the scan tool by the conversion
factor value. The result will be the required value.)
(4) Unit
(5) Standard Value
If the TEST DATA value appearing on the scan tool is out of the
standard value, the O2S is malfunctioning. If it is within the stan-
dard value, the O2S is functioning normally. However, if the val-
ue is on the borderline of the standard value, the O2S may mal-
function very soon.
2. HOW TO READ O2S TEST RESULT USING HAND-
HELD TESTER
(a) Connect the hand-held tester to the DLC3.
(b) On the tester screen, select the following menus: DIAG-
NOSIS / CARB OBDII / O2S TEST RESULT. A list of the
O2S equipped on the vehicle will be displayed.
