TROUBLESHOOTING
2-6-4. Vibrator force is low in ECO mode
Vibration mode change switch must be “CONT” (continuous mode).
Vibration select switch must not be “ ”.
Throttle switch must be “MID”.
ECO lamp is ON.
Reference Fig. : 2-6-1
Check point Check/Cause Action
1. Connector Check MID speed control relay (B-2) (terminal 5)
connector and ECO controller (terminal C1-P8) for
corrosion, breakage, bending and looseness.
If any abnormality is found, connector is faulty.
•
•
Replace connector or
terminal.
2. Harness Measure resistances between MID speed control relay
(B-2) terminal 5 wire G and ECO controller terminal C1-P8
wire G.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
3. 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 : 24V
(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.
