The defect
CERTAIN TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS." THE TRAILER LIGHT LINE MAY HAVE BEEN ROUTED USING TOO TIGHT OF A BEND RADIUS. THIS ROUTING METHOD COULD CAUSE THE WIRES WITHIN THE HARNESS PLUG TO BE PULLED AWAY FROM THE CHASSIS PLUG RESULTING IN AN INTERMITTENT OR COMPLETE ELECTRICAL POWER LOSS TO THE TRAILER.
The risk
SHOULD POWER BE LOST, THE ELECTRICAL CIRCUITS WOULD NOT PROVIDE POWER TO THE ANTILOCK SYSTEM ON THE TOWED VEHICLE INCREASING THE RISK OF A CRASH.
The remedy
DEALERS WILL REROUTE THE LIGHT LINE TO ELIMINATE THE EXCESSIVE BEND RADIUS AND REPLACE ANY PLUG OR HARNESS THAT HAS BEEN DAMAGED FREE OF CHARGE. THE RECALL BEGAN ON APRIL 16, 2007. OWNER MAY CONTACT KENWORTH AT 425-828-5440.
