applied
Reference Fig.: 2-4-1
Check point
Check/Cause
Action
1. F-R Lever Switch
when starter switch is OFF and F-R lever is “F” or “R”,
check continuity between F-R lever switch terminal COM
and terminal NC.
There is no continuity in normal condition.
If there is continuity, F-R lever switch is faulty.
•
•
Replace F-R lever
switch.
2. Parking Brake Switch
when starter switch is OFF and parking brake switch is

•
•
Replace parking brake
switch.
2-4-6. Engine speed cannot be switched
Reference Fig. : 2-4-1
Check point
Check/Cause
Action
1. Throttle Switch
(1) when throttle switch is “IDLE”, check continuity between
throttle switch terminals 1 and 2, 4 and 6.
There is continuity in normal condition.
(2) when throttle switch is “MID”, check continuity between
throttle switch terminals 1 and 3, 4 and 6.
There is continuity in normal condition.
(3) when throttle switch is “FULL”, check continuity
between throttle switch terminals 1 and 3, 4 and 5.
There is continuity in normal condition.
If above item (1), (2) or (3) is NG,
throttle switch is faulty.
•
Replace throttle switch.
2. Throttle Relay (B-1)
(1) when starter switch is ON and throttle switch is “FULL”,
measure voltage between throttle relay (B-1) terminal 1
inlet wire LB and chassis ground.
Standard voltage : 24 V or more
(2) when starter switch is ON and throttle switch is “FULL”,
measure voltage between throttle relay (B-1) terminal 5
outlet wire LW and chassis ground.
There is electricity in normal condition.
(3) when starter switch is ON and throttle switch is “MID”,
measure voltage between throttle relay (B-1) terminal 4
outlet wire WL and chassis ground.
There is electricity in normal condition.
If above item (1) is OK and item (2) or (3) is NG, throttle
relay
(B-1)
is faulty.
•
Replace throttle relay
(B-1).
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.
