178(b) Inspect the combination meter assembly speed input signal
1Inspect voltage
yHold the front wheels up
yPush the shift lever to NEUTRAL
yTurn the ignition switch to ON
ySlowly turn the front wheel, measure the voltage between terminal A9 and A11
Standard voltage is as follows:
Voltage changes alternately
Result and solution:
Normal Replace the combination meter assembly
If abnormal, inspect the speed sensor
2Inspect the speed sensor
y Inspect continuity
Inspect continuity between terminals

1813. TACHOMETER MALFUNCTION
CIRCUIT DIAGRAM
Inspection procedure
(a) Inspect the combination meter assembly revolution input signal
1Remove the combination meter assembly and retain the connection of connectors.
2Connect the oscilloscope to the terminal B11 and
ground.
3Start the engine
4Inspect the signal wave form
Standard:
Show the correct wave form
Result and solution:
NormalInspect and replace the combination
meter assembly
AbnormalInspect the engine ECU revolution out-
put signalEngine ECUCombined Meter Assembly
Engine Revolution Signal

182(b) Inspect the engine ECU revolution output signal
1Remove the engine ECU and retain the connection of connectors.
2Connect the oscilloscope to the terminal 54 and ground.
3Start the engine
4Inspect the signal wave form
Standard:
Show the correct wave form
Result and solution:
NormalRepair or replace the harness or
connector
AbnormalInspect the engine control system

1834. WATER TEMPERATURE GAUGE MALFUNCTION
CIRCUIT DIAGRAM
(a) Get the value of water temperature with the diagnosis tester
1Connect the diagnosis tester to the diagnosis interface
2Turn the ignition switch to ON
3Read the value of engine water temperature displayed on the diagnosis tester
Standard: The same with the actual engine coolant temperature.
Result and solution:
If it is normal, the water temperature gauge has no malfunction
If abnormal, Inspect the combination meter assembly
(b) Inspect the combination meter assembly
1Inspect resistance
yRemove the combination meter assembly and disconnect connectors
yInspect continuity between terminalsWater Temperature SensorCombined Meter Assembly
