c. Type 3. The loader arms and bucket operation stops. This occurs when the loader arm potentiometer or the bucket
potentiometer indicates one of the following conditions:
Part is defective.
Cables become grounded.
Cables are connected to supply voltage.
System is not calibrated.
This type of failure is also caused by a speed value which is outside the limits or by a wrong internal reference voltage
which deactivates loader detector measurement but leaves the electronic control box in an operative condition.
Switching to BACKHOE can interrupt error codes, but error flags are not erased. To move, the loader must be turned
off, then restarted in C130 LIMP mode.
d. Type 4. The electronic control box is inactive. It only shows this error code. This happens when one of the following
occurs:
An internal failure is detected.
A supply output terminal is overloaded.
A control valve output is grounded.
A control valve output is connected to the supply voltage, which deactivates either the electronic
control box or the control valve control circuits.
