1997 VOLVO VOLVO TRUCK recalls

CERTAIN HEAVY DUTY CLASS 8 VEHICLES FAIL TO COMPLY WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS", S5.1.6.3, "ANTILOCK POWER FOR TOWED VEHICLES." ELECTRICAL POWER FOR THE TRAILER ANTI-LOCK BRAKING SYSTEM (ABS) CAN BE DISRUPTED WHEN A SWITCH LOCATED ON THE VEHICLE INSTRUMENT PANEL IS ACTIVATED TO CONTROL LIGHTING WITHIN THE TRAILER.

IF THIS CONDITION OCCURS, THE DRIVER CAN LOSE OF THE TOWED VEHICLE, POSSIBLY RESULTING IN A VEHICLE CRASH.

DEALERS WILL INSTALL A WIRING HARNESS WHICH WILL PROVIDE CONTINUOUS ELECTRICAL POWER TO THE TRAILER ABS WHENEVER THE IGNITION SWITCH IS IN THE ON OR RUN POSITION.

OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT VOLVO TRUCKS AT 1-800-528-6586.
