37Service Manual – SC6000 04 - Control System
Code Description Comments
1-103 H2 Short The controller has detected a short at the optional backup alarm (located
above the squeegee).
• The most likely cause is a damaged coil with an internal short.
• Check the coil resistance of the horn. If it is signicantly below the normal
coil resistance of 5.8 Ω, then replace the horn.
1-104 LP1,2 Short The controller has detected a short at the optional headlights (LP1 or LP2).
• The most likely cause is a short in the wires leading to the headlight due
to chafng or melting.
• Disconnect both headlights. If the condition clears, at least one of the
headlights is faulty.
1-105 H1 Short The controller has detected a short at the horn.
• The most likely cause is a damaged coil with an internal short.
• Check the coil resistance of the horn. If it is signicantly below the normal
coil resistance of 5.8 Ω, then replace the horn.
1-106 M8 Short The controller has detected a short at one of the optional detergent pumps
under the operator’s seat.
• The most likely cause is a loose wire at the pump touching the other
terminal.
• Swap the pump wires (pump 1 for 2) according to the color codes below.
− If the controller thinks the same pump is faulty, then you know the short
is in the wires.
− If the controller thinks the other pump is faulty, then you know that one
of them is faulty. (disconnect each one to nd out which one is faulty).
Positive Negative
Pump 1 Green/Red Orange/Gray
Pump 2 Blue/Yellow Red/White
1-107 M9 Short
1-201 Level Sensor The controller has detected an abnormal condition from the 4 level sensors
in the solution tank, such as a middle sensor indicating differently than
adjacent sensors.
