Front Radar, Failure

VN
SP 366-003, Front Radar, Failure

(March 2016)

Certain VOLVO VN trucks built between 11/11/2013 and 01/14/2015, equipped with front

radar may experience loss of front object detection or erratic operation of cruise control

functions. The terminal seals of the harness is allowing moisture and corrosion to build up in

the front radar harness. To ensure proper operation of the front radar, the harness is

inspected for the proper seal and/or corrosion. If the harness or seal fail inspection,

replacement of the harness is required. Follow the inspection and repair procedures outlined

in this document.

If the truck is eligible for this repair, call 1-877-986-5862 and provide the following information:

17 digit Vehicle Identification Number (VIN), Product Improvement Number (SP366-003),

Dealer Code, and the Purchase Order (PO) Information.
