Inspection
Tachometer
1 . Connect a test tachometer to the engine, and start the
engine.
2. Check the tachometer for allowable indication error. Replace
if necessary.
Caution
• When removing or installing the tachometer, do not
drop it or subject it to sharp shocks.
Speedometer
1. Using a speedometer tester, check the speedometer for al-
lowable indication error, and check the operation of the
odometer. Replace if necessary.
2. Check the speedometer for fluctuation and/or abnormal
noise.
Caution.
• If significant fluctuation occurs or the speedome-
ter does not move at all, remove the speedometer
cable. If it is normal, replace the speedometer as-
sembly.
• Tire wear and improper inflation will increase
speedometer error.
Fuel gauge
1. Remove the instrument cluster.
2. Apply 12V to terminal 1 G and ground terminal 1 H.
3. Connect the red lead of the SST to terminal 1 E and the black
lead to a negative battery terminal.
4. Set the SST to the resistance values shown in the figure.
5. Verify that the needle indicates the correct values.
Caution
• Continue the above checks for at least two minutes
each to correctly judge the condition.
• The allowable indication error is twice the width of
the needle.
Water Temperature Gauge
1 . Remove the instrument cluster.
2. Apply 12V to terminal 1 G and ground terminal 1 H.
3. Connect the red lead of the SST to terminal 1 K and the black
lead· to a negative battery terminal.
