To Safely Handle the Printed
Circuit Board
Before disassembling the control and touching the
PC board, be sure to remove any static charge
from yourself. Static charge can build up as a
technician works on the control.
Best practice is for the technician to work at
a properly grounded work station and wear a
grounded wrist strap. In place of a proper work
station, the technician should work in an oil- and
solvent-free area and touch a good ground each
time before touching the PC board while servicing
the unit.
Handle the PC board by the edges only.
Do not touch the carbon (black) areas of the
keypad. Skin oils will deteriorate the contact area.
TROUBLESHOOTING
CAUTION
Circuit board may be damaged by static
electricity. Always touch ground before
handling the PC board.
CONTROL/CABLE/PLOW MODULE TEST
CONDITION
POSSIBLE CAUSE
CORRECTIVE ACTION
Control
power light
is not ON.
Snowplow is not connected.
Make sure that the grille plug between snowplow and vehicle is
properly connected.
Incomplete harness
connection(s) or damaged
harness(es).
With the vehicle switched accessory ON, test the 4-pin connector
inside the cab. If pin 1 does not have 12V and/or if pin 4 does not
have ground, use the electrical schematic in this guide to trace
the wires from the connector back to their source. Complete any
incomplete connections and repair or replace any damaged wires
and harnesses.
Harness is connected
incorrectly.
Using the electrical schematic in this guide, verify that harnesses
are properly connected.
Poor connection, damaged
control, or damaged plow
module.
If the problem is not corrected with a properly working control,
replace the plow module.
Plow harness fuse is blown.
Replace blown fuse in plow harness.
Control
power light
is blinking.
Poor connection, damaged
control, or damaged plow
module.
Make sure that all plugs (control, between the snowplow and
vehicle, on the snowplow, etc.) are properly connected.
If all plugs are properly connected, install a properly working
control. If the problem is corrected, replace the PC board and/or
coiled cord in the damaged control.
If the problem is not corrected with a properly working control,
replace the plow module.
Control
power light
is ON but
snowplow
does not
respond.
Harness is connected to
module incorrectly.
Using the electrical schematic in this guide, verify that harnesses
are properly connected.
Blown fuse or damaged
plow module.
Replace all blown fuses on vehicle and snowplow.
If fuses are all intact, check for 12V at all coils and primary terminal
of motor relay. If 12V is missing from any coil or relay, replace the
plow module. If 12V is present, go to next possible cause (below).
Damaged harness(es) or
cable(s).
Perform a Solenoid Coil Activation Test (SCAT) according to the
instructions in this guide. Replace/repair any damaged harnesses
and cables.
Damaged control or
plow module.
Install a properly working control. If the problem is corrected,
replace the PC board and/or coiled cord in the damaged control.
If the problem is not corrected with a properly working control,
replace the plow module.
