Official summary
Customer Advisory Letter for New Cascadia ABS Warning Light Illumination work instructions. Due to the enhanced vigilance of the New Cascadia ABS controller, some fault codes and indicator lights do not necessarily require immediate maintenance attention. DTNA and WABCO are currently jointly working on a long-term corrective plan for the condition.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
