OPERATIONAL ADJUSTMENTS
VEHICLE LIGHTING CHECK
1. Verify the operation of all vehicle front lighting
prior to connecting the snowplow harness.
2. Check the operation of the snowplow lights
with snowplow mounted to vehicle and all
harnesses connected.
Turn signals and parking lamps
Parking lamps ON:
• Both vehicle and snowplow parking lamps
should be ON at the same time.
Driver-side turn signal ON:
• Both vehicle and snowplow driver-side turn
signal lamps should flash at the same time.
Passenger-side turn signal ON:
• Both vehicle and snowplow passenger-side
turn signal lamps should flash at the same
time.
Headlamps
Move the vehicle headlamp switch to the "ON"
position. Connecting and disconnecting the
snowplow lighting harness plug should switch
the lights between vehicle and snowplow as
follows:
Snowplow lighting harness DISCONNECTED:
• Vehicle headlamps should be ON.
• Snowplow headlamps should be OFF.
Snowplow lighting harness CONNECTED:
• Snowplow headlamps should be ON.
• Vehicle headlamps should be OFF.
The dimmer switch should toggle the
headlamps between high and low beam. The
high beam indicator on the dash should light
when headlamps are placed in high beam.
Daytime Running Lamps (DRLs)
An operational check of the vehicle and
snowplow DRLs will depend on the vehicle
model, vehicle DRL system and type of
Isolation Module installed. Due to the
variations in the OEM DRL systems and the
different Isolation Module options available,
checking the functionality of the snowplow
DRLs will depend on the type of module
installed on the vehicle.
With the headlamp switch OFF, activate the
vehicle DRLs.
Snowplow lighting harness DISCONNECTED:
• Vehicle DRLs should be ON.
• Snowplow headlamps should be OFF.
Snowplow lighting harness CONNECTED and
vehicle in DRL mode:
• Check snowplow DRL function per the
type of Isolation Module installed.
Joystick Control or CabCommand Control
The snowplow plugs do need to be connected
to the vehicle harness connectors. The control
power indicator light should light whenever the
control ON/OFF switch and the ignition (key)
switch are both in the "ON" position.
3. Connect all snowplow and vehicle harnesses.
Raise the snowplow and aim the snowplow
headlamps according to the Snowplow
Headlamp Beam Aiming Instructions included
with the headlamps, and any state or local
regulations.
4. Check the aim of the vehicle headlamps with
the snowplow removed.
5. When the snowplow is removed from the
vehicle, install plug covers on the vehicle
battery cable and lighting harness. Insert the
snowplow battery cable and lighting harness
into the cable boot on the snowplow.
CAUTION
On 2-plug electrical systems, plug covers
shall be used whenever snowplow is
disconnected. Vehicle Battery Cable is
12-volt unfused source.
