      100 mph	101.8 to 107.0 mph

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

      Reference: Below 0.5 km/h (0.3 MPH) 

1. Check the output signal wave forms.
   1. Remove the combination meter assy with connectors still connected.
   2. Connect the oscilloscope to the terminals C10-21 and body ground.
   3. Start the engine.
   4. Check the signal wave form according to the condition (s) in the table below.
      ITEM CONDITION
      
      

      Item	Condition
      Tool setting	5 V/DIV, 20 ms/DIV
      Vehicle condition	Driving at approx. 20 Km/h (12.4 mph)

      OK: As shown in the illustration. 

      HINT:

      As the vehicle speed increases, the cycle of the signal wave form narrows.

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

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

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

   OK: Needle position is on (EMPTY). 

3. Connect the terminal 2 and 3 on the wire harness side connector of the fuel sender gauge.
4. Turn the ignition switch to the ON position, then check the position of the receiver gauge needle.

   OK: Needle position is on (FULL).
