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.
   
1)
Reversing the connections of the tachometer will damage the transistor and diodes inside.
2)
When removing or installing the tachometer, be careful not to drop it or subject it to severe shock.

Fuel Gauge
1.
Disconnect the fuel sender connector from the fuel sender.
2.
Connect a 3.4 wattages, 12V test bulb to terminals 1 and 3 on the wire harness side connector.
3.
Turn the ignition switch to the ON, and then check that the bulb lights up and the fuel gauge needle moves to full.

Fuel Gauge Sender
1.
Using an ohmmeter, measure the resistance between terminals 1 and 3 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".

3.
If the height resistance is unsatisfied, 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 Gauge
1.
Disconnect the wiring connector (A) from the engine coolant temperature sender in the engine compartment.
2.
Turn the ignition switch ON. Check that the gauge needle indicates cool. Turn the ignition switch OFF.
3.
Connect a 12V, 3.4 wattages test bulb between the harness side connector No.2 and ground.
4.
Turn the ignition switch ON.
5.
Verify that the test bulb flashes and that the indicator moves to HOT.
If operation is not as specified, replace the engine coolant temperature gauge. Then recheck the system.

Engine Coolant Temperature Sender
1.
Using an ohmmeter, measure the resistance between the terminal 2 and ground.
2.
If the resistance value is not as shown in the table, replace the temperature sender.

Brake Fluid Level Warning Switch
1.
Remove the connector (A) from the switch located at the brake fluid reservoir.
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 pull type. It is located at the side of the parking brake lever.
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.

Seat Belt Switch
1.
Remove the connector from the switch.
2.
Check for continuity between terminals.
