PRE±CHECK
1. DATA LIST
According to the DATA LIST displayed by the hand±held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
method to shorten work time.
(a) Warm up the engine.
(b) Turn the ignition switch to OFF.
(c) Connect the hand±held tester to DLC3.
(d) Turn the ignition switch to ON.
(e) Operate the hand±held tester according to the steps on the display and select ºDATA LISTº.

If the value is º±40 Cº or º140
Cº, sensor circuit is open or
shorted.
2. SET BUZZER OFF MODE (SEAT BELT)
(a) Within 6 seconds after turning ignition switch to the ON position, depress the ODO/TRIP switch for 10
seconds or more, and fasten the driver's seat belt to enter the buzzer ON/OFF mode.
HINT:
This procedure can be performed when the display shows the ºODOº mode.
(b) When entering the buzzer ON/OFF mode, current buzzer condition is shown on the display. According
to the display, select the buzzer OFF mode by operating the ODO/TRIP switch.
HINT:

After entering the buzzer ON/OFF mode, when the ODO/TRIP switch is not operated for 10 seconds
or more, the display returns to the normal mode.

When the negative (±) terminal cable is disconnected from the battery, the buzzer setting returns to
buzzer ON mode.

INSPECTION PROCEDURE
1CHECK DISPLAY(GPS MARK DISPLAY)
(a)Preparation for the pre±check.
(1)Place the vehicle outdoors with a good view of the GPS mark.
(b)Check the screen display. (1)Turn the ignition switch ON.
(2)Turn the power switch of the radio receiver assy ON to display the map.
Standard: ''GPS'' mark appears
NGPROCEED TO NEXT CIRCUIT INSPECTIONSHOWN ON PROBLEM SYMPTOMS TABLE

2 CHECK WHEN THIS HAPPENS
(a) Check the abnormal condition. (1) Check the point in which the trouble occurs.
Standard:
AThe trouble occurs outside the specific area
BThe trouble occurs in the specific area
HINT:
At the place difficult to specify the vehicle position (a by±pass road, a overhand r\
oad, a loop road, or several±
storied car park, etc.), the vehicle position may be out of the point due to t\
he wrong matching.

2 CHECK COMBINATION METER ASSY(POWER SOURCE AND GROUND CIRCUIT)
(a) Remove the combination meter assy.
(b) Check continuity.
(1) Check continuity between the terminal C11±5 of the
combination meter connector and the body ground.
Standard: Continuity.
(c) Check the voltage.
(1) Measure the voltage between the terminal C11±20
of the combination meter connector and the body
ground.
Standard voltage: 10 ± 14 V
(2) Turn the ignition switch to ON.
(3) Measure the voltage between the terminal C11±21,
22 of the combination meter connector and the
body ground.
Standard voltage: 10 ± 14 V

HINT:
The ECM sends information on the water temperature sensor to the meter through the Bean. If there is on
open or short circuit in the water temperature sensor circuit, the ECM outputs DTCs. Perform troubleshooting
with the ºEngine systemº.

ONLY WIRELESS CONTROL FUNCTION DOES NOT OPERATE
(PREPARE NEW OR NORMAL TRANSMITTER OF THE SAME
TYPE VEHICLE)
CIRCUIT DESCRIPTION
The door control receiver receives a signal from the transmitter and sends this signal to the integration relay.
Then, the integration relay controls door operation by sending a door LOCK/UNLOCK signal and a luggage
door (back door) unlock signal to each door lock motor.
