NOTE:
- Do not reverse the connections of the tachometer. This will damage its transistors and diodes.
- When removing or installing the tachometer, be careful not to drop or strike it.




2. Compare the tester tachometer values and vehicle tachometer values under the following conditions:

- Vehicle battery voltage is 13.5 V
- Ambient temperature is 25 degrees C (77 degrees F)
If the result is not as specified, the tachometer may have a malfunction.

5. CHECK LOW OIL PRESSURE WARNING LIGHT
a. Disconnect the O1 switch connector.
b. Connect the terminal 1 of the wire harness side connector to the body ground.
c. Turn the ignition switch ON, and then check that the low oil pressure warning light turns on.

OK:
Low oil pressure warning light turns on

If the result is not as specified, the combination meter may have a malfunction.

6. CHECK BRAKE WARNING LIGHT

If the result is not as specified, the combination meter may have a malfunction.




8. CHECK SEAT BELT WARNING LIGHT FOR PASSENGER SIDE
a. Disconnect the B8 switch connector.
b. Connect terminals 1 and 3 of the wire harness side connector.
c. Turn the ignition switch ON, and then check that the warning light blinks.

OK:
Seat belt warning light for passenger side blinks.

If the result is not as specified, the integration control and panel may have a malfunction.




9. CHECK SEAT BELT WARNING REMINDER BUZZER FOR DRIVER SIDE
