Service bulletin CALFTL54-007

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Customer Advisory Letter for Cab-to-Chassis Redundant Ground Strap Installation - FTL Service Bulletin 54-318. Our records indicate that you are the owner of certain vehicles, and DTNA has decided to share the following documentation with you. On New Cascadia vehicles Penske/Black Horse units built prior to May 23, 2019, cab wiring can be damaged with an incorrect ground location or loose ground connections. This can result in inoperable LIN bus-related steering wheel switches, cruise control dropout, poor AM/FM radio reception, and an inoperable steering wheel clockspring. Installing a redundant ground strap from the main ground junction block (MGJB) to the frame will protect the vehicle from unexpected loss of cab grounding, and restore proper operation of the steering wheel switches, the radio, and the steering wheel clockspring.
