Reference Fig.: 2-4-1
Check point
Check/Cause
Action
1. Alternator
After starting engine, measure voltage between alternator
te wire R and chassis ground.
Standard voltage : At least intermediate engine speed,
14 V or more
If voltage is lower than standard, alternator is faulty.
If voltage is normal and battery is not charged, battery is
faulty.

•
Replace alternator or
battery.
2-4-4. Grid heater does not work (Engine starting performance is bad in cold weather)
Reference Fig. : 2-4-1
Check point
Check/Cause

1. Grid Heater
when starter switch is ON, measure voltage between grid
heater inlet wire B and chassis ground.
Standard voltage : 12 V or more
If voltage is normal, grid heater is faulty.
•
•
Replace grid heater.
2. Grid Heater Relay
(1) when starter switch is ON, measure voltage between
grid heater relay terminal 1 inlet wire GW and chassis
ground.
Standard voltage : 12 V or more
(2) when starter switch is ON, measure voltage between
grid heater relay terminal 3 inlet wire B and chassis
ground.
Standard voltage : 12 V or more
(3) when starter switch is ON, measure voltage between
grid heater relay terminal 5 outlet wire B and chassis
ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK and item (3) is NG, grid
heater relay is faulty.
•
Replace grid heater
relay.
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.
(NOTICE)
If any abnormality is found in shielded twisted wires,
repair is not approved. Be sure to replace them.
