INSPECTION OF ANALOG METER
Speedometer
1. Using a speedometer tester, check the speedom-
eter for allowable indication error, and check the
operation of the odometer. Replace if necessary.
2. Check the speedometer for fluctuation and/or ab-
normal noise.
Caution
a) If significant fluctuation occurs or the
speedometer does not move at all, remove
the speedometer cable. If normal, replace
the speedometer assembly.
b)Tire wear and improper inflation will in-
crease speedometer error.
Tachometer
1. Connect a test tachometer to the engine, and start
the engine.
2. Check the tachometer for allowable indicator er-
ror. Replace if necessary.
Caution
When removing or installing the tachometer,
be careful not to drop it.
Fuel Gauge
1. Disconnect the connector from the fuel tank unit.
86U15X-031
Connect the red lead of the SST to the terminal
"Y", and the black lead to a body ground.

3. Set the SST to the resistance values shown in the
figure.
4. Turn the ignition switch ON, and check that the
needle indicator displays the correct values.
If the needle displays correctly, check the gauge
unit. If not, replace the fuel gauge in the meter or
repair the wiring harness.
Caution
a) Continue the above checks for at least two
minutes each to correctly judge the con-
dition.
b)The allowable indication error is twice the
width of the needle.
Water Temperature Gauge
1. Disconnect the connector from the water thermo
sensor.
2. Connect the red lead of the SST to the connec-
tor, and the black lead to a body ground.
3. Set the SST to the resistance values shown in the
figure.
4. Turn the ignition switch ON, and check that the
needle indicator displays the correct values.
If the needle displays the correct values, the trou-
ble is in the gauge unit; if not, the trouble is in the
meter or the wiring harness.
Caution
a) Continue the above checks for at least two
minutes each to correctly judge the con-
dition.
b)The allowable indication error is twice the
width of the needle.
INSPECTION OF DIGITAL METER
Speedometer
1. Using a speedometer tester, check the speedom-
eter for allowable indication error, and check the
operation of the odometer. Replace the meter as-
sembly if necessary.
2. Check the speedometer for fluctuation and/or ab-
normal noise.
Caution
a) If significant fluctuation occurs or the
speedometer does not move at all, remove
the speedometer cable. If normal, replace
the digital meter assembly.
b)Tire wear and improper inflation will in-
crease speedometer error.
