ELECTRICAL SYSTEM 16-81
Meter, Gauge, Indicator Unit
• Check that the number of segments on the fuel level
gauge [A] matches the resistance value of the variable
rheostat.
○When the terminal [12] is connected, 1 segment in the fuel
level gauge should appear about every 15 seconds.
Variable Rheostat Resistance (Ω) Display Segments
20 6 segments go on
40 5 segments go on
60 4 segments go on
90 3 segments go on
120 2 segments go on
170 1 segment goes on
1 segment and fuel
210 level warning indicator
blinks
If the display function does not work, replace the meter
assembly.
Check 3-12: Speedometer Inspection
•Connect the leads in the same circuit as Check 3-1.
•The speed equivalent to the input frequency is indicated in
the oscillator [A], if the square wave is input into terminal
[10].
○Indicates approximately 60 km/h if the input frequency is
approximately 365 Hz.
○Indicates approximately 60 mph if the input frequency is
approximately 585 Hz.
If the meter function does not work, replace the meter
assembly.
NOTE
○The input frequency of the oscillator adds the integrated
value of the odometer.
○The integrated value of the odometer cannot be reset.
Check 3-13: Odometer Check
•Check the odometer with the speedometer check in the
same way.
If value indicated in the odometer is not added, replace
the meter unit.
NOTE
○The data is maintained even if the battery is discon-
nected.
○When the figures come to 999999, they are stopped and
locked.
○The integrated value of the odometer cannot be reset.
