16-70 ELECTRICAL SYSTEM
Meter, Gauge, Indicator Unit
Fuel Level Gauge Inspection:
•
Connect t he 12 V battery and terminals i n the same man-
ner as specified in the “Liquid Crystal Display (LCD) Seg-
ments Check”.
•
Connect a variable rheostat [A] to terminal [4] and [9] as
shown.
•
Check that the number of segment [B] matches the r esis-
tance value of the variable rheostat.
Resistance (Ω) Number of Segments
0 ∼ 16.5 F6
11.5 ∼ 34.5 5
26.5 ∼ 52.5 4
41.5 ∼ 70.5 3
56.5 ∼ 88.5 2
71.5 ∼ above E1
If this display function does not work, replace t he meter
assembly.
•
Connect an other variable rheostat [C] to terminal [2] and
[9] as shown.
•
Set the hand tester [D] to the DC 10 V range and connect
it to terminals of the variable rheostat as shown.
•
When the 1 segment [E] appears, adjust the variable
rheostat [C] so that the terminal voltage is less than 5.7 V.
○
Then the 1 and FUEL segments should flush.
If this display function does not flush, replace the meter
assembly.
Tachometer Check:
•
Connect t he 12 V battery and terminals i n the same man-
ner as specified in the "Liquid Crystal Display (LCD) Seg-
ments Check".
•
The revolutions per minute (rpm) equivalent to the input
frequency is indicated in the oscillator [A] i f the square
wave (illustrated as shown) would be input into the termi-
nal [7].
○
Indicates approximately 6000 rpm i n case the input fre-
quency would be approximately 200 Hz.
