The problem
VEHICLE DESCRIPTION: FIRE TRUCKS EQUIPPED WITH OSHKOSH ALL-STEER ALL-WHEEL STEERING SYSTEM. THE REAR WHEELS OF A FIRE ENGINE CAN TURN UNINTENTIONALLY IF THE ALL-WHEEL STEERING SYSTEM KEY IS ON AND MOISTURE PENETRATES TO THE WIRE THAT CONNECTS THE STEERING SENSOR TO THE ELECTRONIC CONTROL UNIT (ECU). IT WAS DISCOVERED THAT THE INSULATION COVERING THE WIRES BETWEEN THE SENSOR AND THE ECU HAD BEEN NICKED DURING TIME OF ASSEMBLY. OVER TIME, THE NICK IN THE INSULATION ALLOWED MOISTURE TO PENETRATE TO THE ACTUAL WIRE.
Risk
UNDER THESE CONDITIONS, THE DRIVER CAN EXPERIENCE UNINTENDED TURNING OF A SINGLE OR A TANDUM REAR AXLE, POSSIBLY LEADING TO A VEHICLE CRASH OR INJURY OR DEATH TO A PEDESTRIAN OR FIRE FIGHTER.
What owners should do
DEALERS WILL INSPECT FOR NICKED WIRES AND REPLACE THE WIRE HARNESS. THIS RECALL CAMPAIGN IS 100% COMPLETE.
