TROUBLESHOOTING
2-4-1. Engine will not start (Starter motor does not run) 3/17
F-R lever must be in “N”.
Parking brake switch must be applied.
Foot brake switch must be ON (Brake pedal is not depressed).
Check whether exact meter multiple display shows any error code.
1) when display shows any error code
Reference Fig.: 2-4-1
Error code Check point Check/Cause Action
E01 or E02 1. Connector Check F-R lever potentiometer 1, 2 connector and
traveling controller connector terminal 8, 9, 47, 48,
working controller (C2) connector terminal 1, 2 for
corrosion, breakage, bending and looseness.
If any abnormality is found, connector is faulty.
•
•
Replace connector
or terminal.
2. Harness Measure resistances between F-R lever potentiometer
and traveling/working controller terminal wires.
F-R lever potentiometer 1 terminal wire R and traveling
controller terminal 8 wire R
F-R lever potentiometer 1 terminal wire W and traveling
controller terminal 47 wire w, working controller (C2)
terminal 1 wire W
F-R lever potentiometer 1 terminal wire B and traveling
controller terminal 9 wire B
F-R lever potentiometer 2 terminal wire R and traveling
controller terminal 8 wire R
F-R lever potentiometer 2 terminal wire WR and
traveling controller terminal 48 wire WR, working
controller (C2) terminal 2 wire wR
F-R lever potentiometer 2 terminal wire B and traveling
controller terminal 9 wire B
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.

harness.
3. F-R Lever
Potentiometer 1
(1) when starter switch is ON, measure voltage between
F-R lever potentiometer 1 terminal inlet wire R and
ground terminal 1 wire B.
Standard voltage : 5
± 0.5
V
(2) when starter switch is ON, measure voltage between
F-R lever potentiometer 1 terminal outlet wire W and
ground terminal 1 wire B.
①
When F-R lever is “N”
Standard voltage : 2.5
± 0.015
V
②
When F-R lever is “F”
Standard voltage : 1.2
± 0.02
V
③
When F-R lever is “R”
Standard voltage : 3.8
± 0.02
V
If above item (1) is OK and any of measurements in item
(2) is NG, F-R lever potentiometer 1 adjustment is faulty.
•
Adjust F-R lever
potentiometer 1 or
replace it even if
measurement is out
of standard after
adjustment.
