NHTSA recall 04V283000
Service brakes, air › Supply › Low pressure warning › Switch
Freightliner XC Motorhome Chassis
The defect
Certain motor home chassis fail to conform to the requirements of federal motor vehicle safety standard no. 121, 'air brake systems.' in a situation in which multiple alarms are active, a check engine, stop engine, or similar warning indicator IS given priority over the low air alarm by the instrument system controller software. if the operator does not acknowledge these higher priority alarms, a low air alarm may not be displayed.
The risk
This means that a vehicle could be driven with the air pressure below 60 psi without the low air warning sounding, which could result in a crash.
The remedy
Dealers will re-program the multi-module data controller software. the recall began on july 6, 2004. owners should contact freightliner at 1-800-547-0712.
