The hazard
On certain vehicles, the trailer ABS malfunction warning telltale indicator mounted on the dash does not comply with the requirements of CMVSS 121. The fluorescent light in the sleeper, when on, interferes with proper operation of the Power Line Carrier (PLC) trailer ABS signal, preventing the telltale from functioning. This ABS malfunction warning lamp is redundant to the existing trailer ABS malfunction indicator lamp located on the exterior of the trailer and visible from the driver side mirror. The indicator on the exterior of the trailer is not affected by this defect and will continue to warn the driver in the event of a trailer ABS malfunction. Correction: Since this does not pose any safety risk, no corrective action is required.
