TROUBLESHOOTING
2-5-14. Charge warning lamp remains ON
• Check with engine running.
Reference Fig. : 2-5-2
Check point
Check/Cause
Action
1. Harness
• Disconnect connectors between alternator terminal L and
combination meter.
• Measure resistance between terminals and chassis
ground.
• Alternator terminal L and chassis ground
• Charge warning lamp terminal wire No. 28 wire BrR and
chassis ground
Standard resistance : 100k Ω or more
• If resistance is abnormal, harness is faulty.
Repair or replace
harness.
2. Combination Meter
(Charge warning)
• Measure voltage between combination meter charge
warning lamp terminal outlet wire No. 28 wire BrR and
chassis ground.
Standard voltage : 12 V or more
• If voltage is OK, combination meter is faulty.
• If voltage is abnormal, alternator is faulty.
Replace combination
meter or alternator.
2-5-15. Oil pressure warning lamp remains ON
Reference Fig. : 2-5-2
Check point
Check/Cause
Action
1. Harness
Disconnect connectors between oil pressure switch and
combination meter.
• Measure resistance between oil pressure switch terminal
wire YG and chassis ground.
• Combination meter connector terminal wire No.32 wire
YG and chassis ground.
Standard resistance : 100k Ω or more
• If resistance is abnormal, harness is faulty.
Repair or replace
harness.
2. Oil Pressure Switch
• Disconnect oil pressure switch and check continuity
between its terminals.
There is continuity in normal condition.
• If there is no continuity, oil pressure switch is fautly.
Replace oil pressure
switch.
3. Combination Meter
(Oil pressure warning)
(1) When starter switch is ON, measure voltage between
combination meter terminal wires and ground terminal
wire.
• Battery terminal wire No. 57 inlet wire L and ground
terminal wire No.2 wire B.
• Starter switch terminal wire No.37 inlet wire WY and
ground terminal wire No.2 wire B.
Standard voltage : 12 V or more
(2) When starter switch is ON, measure voltage between
combination meter oil pressure warning lamp terminal
wire No.32 outlet wire YG and chassis ground.
Standard voltage : 12 V or more
• If above items (1) and (2) are OK and no abnormality is
found in oil pressure switch but oil pressure warning lamp
remains ON after starting engine, combination meter is
faulty.
Replace combination
meter.
