Instrument Panel, Gauges and Warning Indicators: Testing and Inspection

INSPECTION

SPEEDOMETER
1. Adjust the pressure of the tires to the specified level.
2. Drive the vehicle onto a speedometer tester. Use wheel chocks as appropriate.
3. Check if the speedometer indicator range is within the standard values.

CAUTION:
Do not operate the clutch suddenly or increase/ decrease speed rapidly while testing.

NOTE:
Tire wear and tire over or under inflation will increase the indication error.




[MPH]






TACHOMETER
1. Connect the scan tool to the diagnostic link connector or install a tachometer.
2. With the engine started, compare the readings of the tester with that of the tachometer. Replace the tachometer if the tolerance is exceeded.

CAUTION:
a. Reversing the connections of the tachometer will damage the transistor and diodes inside.
b. When removing or installing the tachometer, be careful not to drop it or subject it to severe shock.





FUEL GAUGE SENDER
1. Using an ohmmeter, measure the resistance between terminals 1 and 2 of sender connector (A) at each float level.




2. Also check that the resistance changes smoothly when the float is moved from "E" to "F".






CAUTION:
If the height resistance is not within specifications, replace the fuel sender as an assembly.
After completing this test, wipe the sender dry and reinstall it in the fuel tank.

ENGINE COOLANT TEMPERATURE SENDER
1. Using an ohmmeter, measure the resistance between the terminal 2 and ground.






OIL PRESSURE SWITCH
1. Check that there is continuity between the oil press switch terminal and ground with the engine off.
2. Check that there is no continuity between the terminal and ground with the engine running.
3. If operation is not as specified, replace the switch.




4. Connect the oil pressure switch wire harness.
5. Turn the ignition switch ON. Check that the warning lamp lights up. If the warning lamp doesn't light, test the wire harness.





BRAKE FLUID LEVEL WARNING SWITCH
1. Remove the connector (A) from the switch located at the brake fluid reservoir (B).
2. Verify that continuity exists between switch terminals 1 and 2 while pressing the switch (float) down with a rod.





BRAKE FLUID LEVEL WARNING LAMP
1. Ignition "ON"
2. Release the parking brake.
3. Remove the connector from the brake fluid level warning switch.
4. Ground the connector at the harness side.
5. Verify that the warning lamp lights.

PARKING BRAKE SWITCH
The parking brake switch is a push type. It is located at the side of the parking brake pedal.
1. Check that there is continuity between the terminal and switch body with the switch (A) ON.
2. Check that there is no continuity between the terminal and switch body with the switch OFF.
If continuity is not as specified, replace the switch or inspect its ground connection.





DOOR SWITCH
Remove the door switch and check for continuity between the terminals. If continuity is not as specified, replace the door switch.









SEAT BELT SWITCH
1. Remove the connector from the switch.
2. Check for continuity between terminals.










SEAT BELT WARNING LAMP
With the ignition switch turned ON, verify that the lamp glows.
