Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
TSIB 26-07
This bulletin is to provide instructions for clearing DTC 1067 FMI 7 (Pressure Sensor Not Calibrated) and FMI 11 (Primary and Secondary Circuit Pressure Sensor (PS1/PS2) Plausibility Error - BS Pressure), when required to prevent the loss of Adaptive Cruise Control functionality and the illumination of a warning indicator.
TSIB 26-05

These bulletins have been issued to recommend interim inspection procedures required every 6000 miles on specifically equipped motor coaches due to global parts shortages and the subsequent delay in available parts to conduct the corrective actions associated with NHTSA Recall 21V-748.
TSIB 21-10
This Technical Service Information Bulletin describes interim inspection procedures required every 6000 miles on specific motor coaches due to the global parts shortage and subsequent delay in available parts to conduct the corrective actions associated with NHTSA Recall 21V-748.
