STEP 6. Check the wiring harness between
combination meter connector C-04 (terminal 9)
and ignition switch (IG1).
NOTE: Prior to the wiring harness inspection, check
Junction block connectors C-210 and C-212, joint
connector C-03 , and repair if
necessary.
Q: Are the wiring harness between combination meter
connector C-04 (terminal 42) and ignition switch
(IG1) in good condition?
YES :
There is no action to be taken.
NO : Repair or replace the wiring harness. Check
to see that all meters operate.

STEP 7. Resistance measurement at combination
meter connector C-04 to check the earth circuit
to the combination meter.
(1) Disconnect the combination meter connector
C-04 and measure the resistance at combination
meter connector C-04.
(2) Measure the resistance between terminal 1 and
earth.
OK: 2 ohms or less
(3) Measure the resistance between terminal 2 and
earth.
OK: 2 ohms or lessQ: Is the check result normal?
YES :
Repair or replace the connector.
NO : Go to Step 8.
STEP 8. Connector check: Combination meter
connector C-04.
Q: Is combination meter connector C-04 in good
condition?
YES :
Go to Step 9.
NO : Repair or replace the wiring harness. Check
to see that all meters operate.

STEP 9. Check the wiring harness between
combination meter connector C-04 (terminal 1
and 2) and earth.
Q: Are the wiring harness between combination meter
connector C-04 (terminal 1 and 2) and earth in
good condition?
YES :
This procedure is complete.
NO : Repair or replace the wiring harness. Check
to see that all meters operate.
ON-VEHICLE SERVICE
SPEEDOMETER CHECKM1543000900423
Adjust the pressure of tyres to the specified level.
(Refer to GROUP 31, On-vehicle Service P.31-7.)
CAUTION
Do not operate the clutch suddenly. Do not
increase/decrease speed rapidly while testing.
1. Set the vehicle onto a speedometer tester and
use wheel chocks to hold the rear wheels.2. To prevent the front wheel from moving from side
to side, attach tension bars to the tie-down hook,
and secure both ends to anchor plates.
3. To prevent the vehicle from moving, attach a chain
or wire to the rear retraction hook, and make sure
the end of the chain or wire is secured.
4. Check if the speedometer indicator range is within
the standard values.
Standard value:
5. If not to the standard value, inspect for proper tyre
size. If not correct, replace the tyres with original
size tyres and retest. If correct, replace the
speedometer. If still not to standard value, replace
the vehicle speed sensor.
TACHOMETER CHECKM1543001000434
1. Attach an external high quality tachometer to the
engine speed detection connector on the harness
side (such as with a paper clip).

NOTE: For tachometer check, use an external
high quality inductive tachometer.
2. Compare the readings of the vehicle tachometer
and the external tachometer at every engine
speed, and check if the variations are within the
standard values.
Standard values:
FUEL TANK GAUGE UNIT CHECKM1543001200461
Remove the fuel tank gauge unit. (Refer to GROUP
13C, Fuel Tank P.13C-4.)
FUEL TANK GAUGE UNIT RESISTANCE
1. Check that resistance value between the fuel
gauge terminal and earth terminal is at the
standard value when the fuel tank gauge unit float
is between position "F" (highest) and position "E"
(lowest).
Standard values:
2. Check that resistance value changes smoothly
when the float moves slowly between position "F"
(highest) and position "E" (lowest).
3. If all checks are correct, go to fuel tank gauge unit
float height check. If any check is not correct,
replace the fuel tank gauge unit.
FUEL TANK GAUGE UNIT FLOAT HEIGHT
1. Move the float and measure height A at position
"F" (highest) and B at position "E" (lowest) with
the float arm touching stopper.
Standard values:
2. If all checks are correct, go to fuel tank gauge unit
float height check. If any check is not correct,
replace the fuel tank gauge unit.

VEHICLE SPEED SENSOR CHECK
1. Remove the vehicle speed sensor and connect a
3 − 10 kiloohms resistor as shown in the
illustration.
2. Turn the shaft of the vehicle speed sensor and
check that there is voltage between terminals 2 −

3. If within the standard value, the vehicle speed
sensor is OK.
If not within the standard value, replace the
vehicle speed sensor.
