ON CERTAIN HEAVY DUTY TRUCKS EQUIPPED WITH CUMMINS ELECTRONIC CONTROL MODULES ON THE L10G ENGINES, THE ECM DOES NOT HAVE THE ABILITY TO DETECT A THROTTLE FAIL-SAFE ENGINE SHUTDOWN COMMAND. THIS COULD RESULT IN AN UNANTICIPATED, UNCOMMANDED OPEN THROTTLE CONDITION WITHOUT WARNING.
Consequence & remedy
Consequence: IF THIS EVENT OCCURS, THE VEHICLE OPERATOR WILL NOT HAVE CONTROL OF THE ENGINE SPEED, POSSIBLY RESULTING IN A VEHICLE CRASH.
Remedy: CUMMINS WILL NOTIFY THE CUSTOMERS AND REPLACE THE ECM. OWNERS SHOULD CONTACT CUMMINS AT 1-800-343-7357 OR VOLVO TRUCKS AT 1-800-528-6586.
VEHICLE DESCRIPTION: DUAL STEER CLASS 8 HEAVY DUTY TRUCKS. THE FRONT STEER AXLE BRAKES DO NOT COMPLY WITH THE REQUIREMENTS OF FMVSS NO. 121, "AIR BRAKE SYSTEMS."
Consequence & remedy
Consequence: A SLOW BRAKE RELEASE TIME CAN CAUSE PREMATURE BRAKE WEAR WHICH IF LEFT UNCHECKED COULD LEAD TO BRAKE FAILURE AND VEHICLE CRASH.
Remedy: DEALERS WILL INSTALL A RELAY VALVE IN THE FRONT STEERING AXLE BRAKE SYSTEM.
VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. THE AIR SUSPENSION CONTROL VALVE SUPPLY LINE WAS NOT PLUMBED THROUGH AN AIR PRESSURE PROTECTION VALVE. IN THE EVENT OF A FAILURE, THERE WOULD BE LOSS OF AIR PRESSURE IN THE 'B' SYSTEM AIR RESERVOIR THAT SUPPLIES AIR PRESSURE FOR THE FRONT STEER AXLE BRAKES.
Consequence & remedy
Consequence: THIS CONDITION WOULD RESULT IN INCREASED STOPPING DISTANCES.
Remedy: DEALERS WILL INSTALL THE NECESSARY AIR PRESSURE PROTECTION VALVE.
THE TRACTION SOLENOID EXHAUST CAN BE OBSTRUCTED DUE TO INADEQUATE DRAINAGE AND A BUILD-UP OF ROAD CONTAMINATION BETWEEN THE MOUNTING BRACKET AND THE SOLENOID HOUSING. THE OBSTRUCTED EXHAUST PREVENTS THE RELAY VALVE CONTROL AIR PRESSURE FROM VENTING AFTER A DIFFERENTIAL BRAKING TRACTION EVENT.
Consequence & remedy
Consequence: THIS CONDITION WOULD KEEP THE REAR AXLE SERVICE BRAKES APPLIED WITHOUT ANY BRAKE PEDAL MOVEMENT BY THE DRIVER INCREASING THE RISK OF A VEHICLE ACCIDENT.
Remedy: DEALERS WILL REMOVE THE SUSPECT VALVE AND INSTALL A NEW VALVE THAT HAS A MODIFIED SOLENOID HOUSING WHICH WILL ALLOW FOR SUFFICIENT DRAINAGE AND A NEW VALVE MOUNTING BRACKET WITH INCREASED HEIGHT TO REDUCE ENTRY OF CONTAMINATION.
