connector terminal 5, 12 for corrosion, breakage, bending
and looseness.
If any abnormality is found, connector is faulty.
•
•
Replace connector
or terminal.
2. Harness
Measure resistances between speed sensor and
traveling/working controller terminal wires.
Speed sensor terminal 2 wire YW and traveling
controller terminal 26 wire G, working controller (C1)
terminal 5 wire G
Speed sensor terminal 3 wire W and traveling controller
terminal 46 wire w, working controller (C1) terminal 12
wire W
Speed sensor terminal 4 wire R and traveling controller
terminal 8 wire R
Speed sensor terminal 5 wire B and traveling controller
terminal 9 wire B
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.

Repair or replace
harness.
3. Speed Sensor (1) when starter switch is ON, measure voltage between
speed sensor terminal 4 inlet wire R and ground
terminal 5 outlet wire B.
Standard voltage : 5
± 0.25
V
(2) Start engine and rotate vibratory drum. Measure pulse
between speed sensor terminal 3 outlet wire W and
terminal 5 outlet wire B with a pulse meter.
Standard pulse : 21 pulses/rotation
If above item (1) is OK and item (2) is NG, speed sensor
is faulty.
•
Replace speed
sensor.
4. Traveling/
Working
Controller
If error code E11 is displayed and no abnormality is

When repair is complete, start engine.
②
Exact meter will display E11.
③
Move F-R lever “F” or “R” and run machine.
