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
(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
