| SB54-331 | 2020-09-16. Service bulletin. Updated Freightliner Service Bulletin for Updated ULB Control Unit for LED Headlamps. This bulletin replaces the version dated July 30, 2020. Information about a reman part has been added. New Cascadia vehicles with light emitting diode (LED) headlamps built from January 1, 2017 through February 17, 2020 may experience intermittent disabled headlamps due to an issue with the universal light ballast (ULB). The LED headlamps can turn off if the supply voltage drops below approximately 9V. This low voltage commonly and momentarily occurs when cranking the engine on a vehicle with batteries that are not fully charged. The momentary low voltage may cause the electronic ULB control unit to malfunction. The ULB may not resume normal function until the power supply to the headlamp is disconnected. |

| SB54-333 | 2020-07-30. Service bulletin. Service Bulletin for Installing a Fog Lamp Backshell. The connector that attaches to the fog lamp is exposed to water spray from the front tires. Even though the connector is sealed, water spray, in addition to wiring that may be pulled sideways, can cause water intrusion into the connector. A backshell can be added to the connector to provide shielding from direct water spray. It also provides strain relief for the wires entering the connector. |
