1998 VOLVO WG recalls

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.

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.

DEALERS WILL REPLACE THE ABS ECU.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH HALDEX MANIFOLD DASH VALVES (MDV) USED IN TRACTOR AND TRAILER PARKING BRAKES. THESE VALVES DO NOT MEET THE REQUIREMENTS OF FMVSS NO. 121, "AIR BRAKE SYSTEMS." A LOSS OF THE ISOLATION OF THE TWO BRAKE SYSTEM CIRCUITS CAN RESULT IN THE LOSS OF SERVICE BRAKES WHEN THERE IS ANOTHER FAILURE OF ONE OF THE TWO BRAKE CIRCUITS.

THE LOSS OF SERVICE BRAKES CAN OCCUR, INCREASING THE RISK OF A CRASH.

DEALERS WILL REPLACE THE SUSPECT VALVES.

CERTAIN HEAVY DUTY CLASS 8 TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108, "LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT." THE TWO TAIL LAMPS, BACK-UP LAMP,AND LICENSE TAG LAMP WERE MOUNTED ON INSUFFICIENTLY RIGID MOUNTS.

IT MAY NOT ALLOW THE DRIVER OF A REARWARD APPROACHING VEHICLE TO HAVE FULL VIEW OF THE LAMPS.

DEALERS WILL ATTACH THE TWO TAIL LAMPS, BACK-UP LAMP, AND THE LICENSE TAP LAMP ON STIFFER BRACKETS. OWNER NOTIFICATION BEGAN OCTOBER 31, 2002.

THIS CONDITION WOULD RESULT IN INCREASED STOPPING DISTANCES.

DEALERS WILL INSTALL THE NECESSARY AIR PRESSURE PROTECTION VALVE.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH A FAL 8.0 FRONT STEER AXLE. THE UPPER STEERING ARM CAN FAIL WITHOUT WARNING.
