Blue Bird Field Service started fielding reports of this failure in September of 2022. PHRED 562 was opened October 28, 2022 to track and 8D the problem. Replacing clusters with applicable service parts did not resolve the problem, however, installing Part Number 10068500 (nonvideo) would allow the system to work properly. All external influences of cluster internal were eliminated. Internal audit of cluster software/hardware found the copy of the ignition signal that the co-processor (only used with 7 gauge clusters) reads to start running was being loaded down by an internal pulldown in the co-processor (Magna-V) itself. It is loaded to a level that is marginal to be read as a valid high when cold. If the co-processor does not see ignition, it will not run and the air gauges + low air warnings will not be active.

FMVSS 1 : 121 – Air brake systems FMVSS 2 : NR Description of the Safety Risk : In the absence of functioning air gauges and visual/audible warning, a driver would not have warning if brake air pressure was lost. Causing brake air pressure loss would result in non functioning brakes, therefore, increasing the chance of a crash. Description of the Cause : Some T3 and CVEV units equipped with pneumatic brakes have been found to inconsistently not have functioning air pressure gauges, and visual/audible low air warnings on startup in ambient <=50°F (10°C) temps. Software glitch / bug Identification of Any Warning that can Occur : A driver would be able to visually identify non functioning air gauges which is a pre-trip check requirement on air brake equipped buses.
