175II. DETAILED SOLUTION PROCEDURE1. THE WHOLE COMBINATION METER
DOSE NOT OPERATE.
(a) Inspect fuse
1Check fuse CLUSTER (10A) in the main fuse
box for continuity.
2Check fuse AM (30A) in the main fuse box
for continuity.
3Check fuse MAIN (80A) in the fuse box for
continuity.
Result and solution: If a certain fuse is burnt, replace a fuse
with the same capacity.Ignition SwitchMain Fuse BoxCombined Meter AssemblyBatteryFuse Box

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

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
