Steps 2 through 5 are needed only if the vehicle does
not support PLC.
2. Using a diagnostic tool, look for an active Trailer ABS
Warning Lamp Open (Dash Mounted) Diagnostic Trouble
Code (DTC). The DTC will be found as an active DTC,
however, the ABS indicator lamp will not be illuminated.
See Figure 2 for typical ACom
™

®
ACom
™
Diagnostics (version 5.9
or higher) is required. The technician will need to open the
confi guration screen and see if the current confi guration
shows PLC being used. In addition, verify that the in-cab
trailer lamp (located under "Antilock" in the confi guration
window) is confi gured for PLC.
4. To change the setting, select the "Modify" button on the
right side of the confi guration screen to open the "Change
Confi guration" window. See Figure 4.
Click inside the box to remove the check mark, disabling
the In-Cab Trailer Lamp.
