Procedure

Table 2

IMPORTANT: When the campaign has been completed, locate the base completion label in the appropriate
location on the vehicle, and attach the gray completion sticker provided in the field service kit (Form WAR261). If
the vehicle does not have a base completion label, clean a spot on the appropriate location of the vehicle and first
attach the base completion label (Form WAR259). If a field service kit is not required or there is no completion
sticker in the kit, write the campaign number on a blank sticker and attach it to the base completion label.

Work Instructions
Subject: Qualcomm TrailerTRACS Wiring
Models Affected: Specific Freightliner Cascadia vehicles manufactured January 1, 2010, through January 14, 2013.

Work Instructions
1. Check the base label (Form WAR259) for a completion sticker (Form WAR261) for campaign SF480A indicating
this work has been done. The base label is usually located on the passenger-side door about 12 inches (30
cm) below the door latch. If a completion sticker is present, no work is needed. If a completion sticker is not
present, proceed with the next step.
2. Shut down the engine and apply the parking brakes. Chock the tires.
3. Access the driver-side wiring harness.
NOTE: There are three possible configurations.
• On vehicles equiped with a driver-side luggage compartment, the wiring harness cover is located on the
inside front edge of the compartment. See Fig. 1.Open the compartment and remove all the stored items.
Remove the fasteners from the harness cover, then remove the cover.
• On vehicles without a driver-side luggage compartment, the harness is under the side panel located beneath
the lower bunk. Raise the bunk and remove the support panel. Remove the bolt that secures the side panel
to the cab floor, then remove the side panel. See Fig. 2.
• On daycabs, the harness is located behind the back wall upholstery panel. Remove this panel.

4. Inspect circuit 45 to make sure that the wiring modification was not completed prior to this campaign. If the
procedure was already performed, circuit 45 will be spliced with an 18-gauge wire and routed as shown in
Fig. 5. If the procedure has already been done, clean a spot on the base label (Form WAR259). Attach a
completion sticker (Form WAR261) for campaign SF480 to the base label. Otherwise, proceed with the next
step.
5. Remove the tread plate, kick panel, and lower dash panel from the passenger side of the vehicle. See Fig. 3.

passenger-side wall, and under the passenger-side kick panel to the Qualcomm ECU connector under
the dash.

6.2

Feed the wire through the fuse holder. Strip the wire, then crimp on the fuse holder terminal end.

6.3

Cut a 4 to 6 inch (10 to 15 cm) strand of wire.

6.4

Feed the short strand of wire through the fuse holder. Strip the wire on both ends, then crimp on the
fuse holder terminal end.

7. Inside the cab, cut and strip the circuit 45 blue wire.
8. Splice the new wire into circuit 45. See Fig. 5.
8.1

Slide a butt connector onto the the end of circuit 45 that leads to the SAM Chassis.

8.2

Slide the new wire and the other end of circuit 45 into the opposite end of the butt connector.

8.3

Crimp each end of the butt using a crimp tool to secure the wires. See Fig. 6.

8.4

Pull test the wires by hand to ensure the crimp is mechanically solid.

8.5

Heat the splice using a heat gun rated at 1,000 F (538 C) until the sleeve has completely shrunk against
the wire and the solder inside the butt connector flows.
