      2. If the result is not specified, the speedometer may have a malfunction.



3. CHECK TACHOMETER
  1. Check operation.

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

      NOTICE:
      1. Do not reverse the connections of the tachometer. This will damage its transistors and diodes.
      2. 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:

      1. Vehicle battery voltage is 13.5 V
      2. Ambient temperature is 25°C (77°F)
