2-6-2. Amplitude does not change (Remains either low or high) 3/3
Vibration mode change switch must be “CONT” (continuous mode).
Vibration select switch must not be “ ”.

Check point Check/Cause Action
6. ECO controller (1) when starter switch is ON, measure voltage between
ECO controller terminal C1-P2 inlet wire YB and chassis
ground.
Standard voltage : 24 V
(2) when starter switch is ON and vibration select switch
is “ ” or “
”, measure voltage between
ECO
controller terminal wires and chassis ground.
“ ” : ECO controller terminal C1-P9 inlet wire YR
and chassis ground.
“ ”
: ECO controller terminal C1-P10 inlet wire YB
and chassis ground.
Standard voltage : 24 V
(3) Check ECO controller terminal C1-P1 wire B is
grounded.
(4) when starter switch is ON and throttle switch is
“MID”, voltage between ECO controller terminal C1-P8
inlet wire G and chassis ground.
Standard voltage : 24 V
(5) After starting engine and vibration select switch is
“ ” or “
”, measure current between
ECO
controller terminal wires and chassis ground.
“ ” : ECO controller terminal C1-P11 outlet wire RL
and chassis ground.
Standard current : 450 mA (at throttle switch is “MID”)
: 340 mA (at throttle switch is “FULL”)
“ ”
: ECO controller terminal C1-P12 outlet wire
RY and chassis ground.
Standard current : 450 mA (at throttle switch is “MID”)
: 330 mA (at throttle switch is “FULL”)
If above items (1), (2), (3) and (4) are OK and item (5) is
NG, ECO controller is faulty.
(NOTICE)
Since current value is output in PWM, standard value
shown above represent a maximum instaneous value.
•
•
Replace ECO controller.
7. 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.
