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
