TROUBLESHOOTING
2-5-1. Machine and engine suddenly stops 9/11
Starter motor runs for only 2 seconds when starter switch is turned to START.
Check whether exact meter multiple display shows any error code.
1) when display shows any error code
Reference Fig.: 2-5-1
Error code Check point Check/Cause Action
E44, E45 1. Connector Check exact meter connector terminal 1, 2, 7 and working
controller (C1) connector terminal 3, 4, working controller
(C2) connector terminal 9 for corrosion, breakage,
bending and looseness.
If any abnormality is found, connector is faulty.
•
•
Replace connector
or terminal.
2. Harness Measure resistances between exact meter and working
controller terminal wires.
Exact meter terminal 1 wire GW and working controller
(C1) terminal 3 wire Gw
Exact meter terminal 2 wire B and working controller
(C1) terminal 4 wire B
Exact meter terminal 7 wire LgB and working controller
(C2) terminal 9 wire LgB
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.

•
Replace harness.
3. Working
Controller
(1) when starter switch is ON, measure voltage between
working controller (C1) power supply terminal 2 inlet
wire WB and ground terminal 1 outlet wire B.
Standard voltage : 12 V or more
If above item (1) is OK and (2) is NG, working controller
(C1) is faulty.
(2) when starter switch is ON, measure voltage between
working controller (C2) power supply terminal 11,
12 inlet wire WB and working controller (C1) ground
terminal 1 outlet wire B.
Standard voltage : 12 V or more
(3) when starter switch is ON, measure voltage between
working controller (C2) terminal 9 inlet wire LgB and
working controller (C1) ground terminal 1 outlet wire B.
Standard voltage : 12 V or more
If above items (1), (2) are OK and (3) is NG, working
controller (C1) is faulty.
•
•
Replace working
controller.
4. CAN
Communication
(E44 only)
A normally operating working controller sends connection
verification signals to exact meter every 0.1 second. Exact
meter cannot receive connection verification signals that
are regularly sent from working controller for 1 continuous
second while operating.
Working controller is faulty.
•
•
Replace working
controller.
5. Clearing
Error Code
and Judging
OK/NG after
Repair
①
when repair is complete, set starter switch to ON.
②
Place F-R lever “N”.
Exact meter will display vehicle speed. Machine is in
normal state.
If display does not change to vehicle speed, check
above items again.
