Defect: CERTAIN TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS."

Consequence: 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.
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.
