   NOTE: Tire wear and tire over or under inflation will increase the indication error. 
2. Check the deflection width of the speed meter indicator.

   Reference: Below 0.5 km/h/0.3 mph 

1. While driving the vehicle at the speed of 10 km/h, check the voltage between the terminals S1 and body ground of the combination meter assy.

   Standard: Fluctuation between 10 to 14 V or less is repeated 7 times within 1 sec. 

   NOTE: Check it with the ignition switch ON and the connector connected. 

1. Connect a tune-up test tachometer, and start the engine.
   NOTE:

   • Reversing the connection of the tachometer will damage the transistors and diodes inside. 
   • When removing or installing the tachometer, be careful not to drop or subject it to heavy shocks. 
2. Compare the test and tachometer indications.

1. Disconnect the connector from the sender gauge.
2. Turn the ignition switch ON, then check the position of the receiver gauge needle.

   Needle position: EMPTY 

3. Connect terminals 2 and 3 on the wire harness side connector and turn the ignition switch ON, then check the position of the receiver gauge needle.

   Needle position: FULL 

1. Disconnect the connector from the sender gauge.
2. Turn the ignition switch ON, check the fuel level needle indicates EMPTY and fuel level warnin lights light on.

1. Disconnect the connector from the sender gauge.
2. Turn the ignition switch ON, check the position of the water temperature receiver gauge needle.

   Needle position: COOL 

3. Ground terminal 2 on the wire harness side, then check the position of the water temperature receiver gauge needle.

   Needle position: HOT 

1. Turn the ignition switch ON and check that the warning light lights up.
2. Fasten the outer belt to the inner belt and check that the warning light lights out.
3. Disconnect the connector from the buckle switch and ground terminal on the wire harness side connector.
4. Turn the ignition switch ON and check that the warning light lights up.

1. Turn the ignition switch ON, then with the passenger being seated on the passenger seat, check that the seat belt warning light in the heater control panel lights.

1. Disconnect the connector from the front seat inner belt.
2. Connect terminals 2 and 4 on the wire harness side connector.
3. Turn the ignition switch ON and check the warning light.

   Warning light: light up 

1. Disconnect the connector from the low oil pressure switch.
2. Turn the ignition switch ON.
3. Connect the terminal of wire harness side connector and ground, then check the warning low oil pressure warning light.

   Low oil pressure warning light: Light on 

HINT:

When the key unlock warning and light auto turn off warning is output simultaneously, the key unlock warning precedes the other.

1. While the driver side door is open, insert the ignition key, set the ignition switch to OFF (LOCK or ACC) and check for the buzzer sound.

   Buzzer sound: Intermittent 

1. Disconnect the connector from the parking brake switch and ground terminal on the wire harness side connector.
2. Turn the ignition switch ON and check that the warning light lights up.

1. Disconnect the connector from the brake fluid level warning switch and connect terminals on the wire harness side connector.
2. Turn the ignition switch ON and check that the warning light lights up.

1. Remove the reservoir tank cap and strainer.
2. Disconnect the connector.
3. Check that the continuity exists between the terminals.

   Float up (switch off): No continuity 

4. Use syphon, etc., to take fluid out of the reservoir tank.
5. Check that the continuity exists between the terminals.

   Float down (switch on): Continuity 

6. Pour the fluid back in the reservoir tank.

1. Disconnect the connector from the warning switch and ground terminal on the wire harness side connector.
2. Engine running and check that the warning light lights up.

1. Turn the ignition switch ON and check that the driver's seat belt warning sounds if the driver's seat belt is not fastened.
2. Check that the buzzer stop after about 4 to 8 seconds.
