Component: SERVICE BRAKES, AIR:ANTILOCK

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.

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

Remedy: 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. OWNER NOTIFICATION BEGAN APRIL 29, 2002. 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.

Component: SERVICE BRAKES, AIR:ANTILOCK

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS BUILT WITH BENDIX AIR ABS WITH AN EC-17 1030R ELECTRONIC CONTROL UNIT (ECU), THERE HAVE BEEN REPORTS OF UNWANTED ABS ACTIVATION AT LOW SPEEDS CAUSED BY 1) CHAFED ABS WHEEL SPEED SENSOR WIRES ON ROTATING PARTS OR 2) A DAMAGED COMPONENT AT THE WHEEL END THAT GENERATES A CERTAIN TYPE OF ERRATIC SENSOR SIGNAL.

Consequence: THIS CONDITION COULD CAUSE THE ABS ECU TO EXHAUST THE AIR AT THE AIR BRAKE MODULATORS FOR ONE OR MORE OF THE WHEELS. THIS COULD RESULT IN EXTENDED BRAKING DISTANCES AND A POSSIBLE CRASH.

Remedy: DEALERS WILL REPLACE THE ABS ECU.

Component: WHEELS:RIM

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH AFTERMARKET ALUMINUM DUAL WHEELS, 22.5X8.25, ONE-PIECE, TUBELESS, SUPPLIED BY ACCURIDE/AKW. CERTAIN DESIGN REVISIONS COMBINED WITH PROCESS CONDITIONS CAUSED FATIGUE CRACKS IN THESE WHEELS.

Consequence: THIS CONDITION CAN CAUSE FAILURE OF THESE WHEELS.

Remedy: ACCURIDE/AKW WILL REPLACE THESE WHEELS.

Component: SUSPENSION:FRONT:WHEEL BEARING

VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. THE STEER AXLE WHEEL BEARING JAM NUT LOCK WASHER MAY NOT HAVE BEEN BENT OVER THE JAM NUT AFTER THE WHEEL BEARINGS WERE ADJUSTED.

Consequence: IF THIS CONDITION EXISTS, THE JAM NUT AND WHEEL BEARING ADJUSTING NUT CAN BACK OFF THE SPINDLE ALLOWING THE WHEEL AND THE BRAKE DRUM ASSEMBLY TO SEPARATE FROM THE VEHICLE INCREASING THE RISK OF A VEHICLE CRASH.

Remedy: DEALERS WILL INSPECT THE STEERING AXLE WHEEL BEARING JAM NUT LOCK WASHER TO DETERMINE IF IT IS BENT OVER THE JAM NUT, AND IF NOT, REPAIR AS REQUIRED.
