• If the headlights and markers lights function correctly, and if there is voltage at the low beam
output pin(s) at the plow light connector(s), then go to the next step.
• If the headlights and marker lights in the headlight assembly do not turn off, and all other
marker lights remain on when the plow switch is turned on, check the installation of the wiring
harnesses and re-check the function.
• If voltage is not present at the low beam output pin(s), verify that the parameters were set correctly, and check the wiring installation, especially the connection at the XMC2, then re-check
the function.
