VEHICLE SPEED CONTROL

Defect

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.

Safety Risk

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.
