POSSIBLE FAULT/ERROR
ACTION/CHECK
•
One or more of the sensor eyes are
not
connected to the ECU or sensor eye.
•
One or more of the sensor leads are shorting to
ground.
•
One or more of the sensor leads are split or
open circuit.
Ensure the sensor terminal connectors are firmly
located in position to both the ECU & sensor eyes.
Using a multi-meter, ensure none of the sensor
leads are shorting to ground.
Examine each lead for lacerations, if no open
circuits are found, remove the first sensor eye and
loosely run a new sensor lead to the ECU port 1,
ENSURE THE EYE IS REPLACED prior to
testing,
repeat for each sensor eye.
Replace the sensor eye & carry out the set-up procedure
on Pg 5.
•
One of the sensor eyes are inoperative.
Examine each lead for lacerations, if no open circuits are
found, remove the first sensor eye and loosely run a new
sensor lead to the ECU port 1,
ENSURE THE EYE IS
REPLACED prior to testing,
repeat for each sensor
eye.
•
One or more of the sensor leads are split or
open circuit.
Check each sensor lead connection and ensure the
sensor terminal connectors are firmly re-located in
position to both the ECU & sensor eyes.
•
One of the sensor leads has become dislodged
from the back of the sensor eye or ECU
POSSIBLE FAULT/ERROR
•
One of the sensor eyes may be too tight or
pressing against an object to its rear.
ACTION/CHECK
•
The sensor eyes may be dirty or have ice on
the surface.
•
The small spot on the front of each sensor eye
may not be at the top.
Ensure at least 23mm depth to accommodate the sensor
eye.
•
The sensor eyes may be dirty or have ice on
the surface.
•
The sensor eyes may be pointing down and
picking up undulations in the ground.
Ensure the sensor eyes are clean.
The system may be suffering from “Ground Effect” refer
to diagram 8.
Ensure the sensor eyes are clean.
POSSIBLE FAULT/ERROR
ACTION/CHECK
•
The small spot on the front of each sensor eye
may not be at the top.
