TROUBLESHOOTING
2-6-12. Temperature meter is abnormal
Reference Fig.: 2-6-2
Check point Check/Cause Action
1. Thermo Unit Disconnect harness and measure resistance of thermo
unit.
Standard resistance :
164.6 Ω (at unit temperature of 50°C)
26.44 Ω (at unit temperature of 103°C)
If resistance is abnormal, thermo unit is faulty.
•
•
Replace thermo unit.
2. Combination Meter
(Temperature meter)
when starter switch is ON, measure voltage between
combination meter terminal wires and ground terminal
wire.
Battery (12 V) terminal wire No.73 inlet wire L and
ground terminal wire No.2 wire B
Starter switch (ACC) terminal wire No.65 inlet wire Y
and ground terminal wire No.2 wire B
Standard voltage : 12 V or more
If no abnormality is found, combination meter is faulty.
•
•
•
•
Replace combination
meter.
3. Harness Connecting
Between Terminals
Measure resistance of harness connecting between
terminals.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
