Motor Coach Industries primary air line was incorrectly hooked to the secondary air pressure gauge and the secondary air line was hooked to the primary air pressure gauge.
The short version
Motor Coach Industries reported a problem with the supply hoses, lines/piping, and fittings. Here is what owners need to know.
The primary air line was incorrectly hooked to the secondary air pressure gauge and the secondary air line was hooked to the primary air pressure gauge. As such, these buses fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
The incorrect air pressure readings may increase the risk of a crash by delaying the driver's reaction to addressing the low air condition.
MCI will notify owners, and dealers will inspect the air lines for proper connection, repairing them as necessary, free of charge.
