TSB16-0098

SOME 2011-2016 F-SUPER DUTY VEHICLES EQUIPPED WITH A 6.7L DIESEL ENGINE THAT ARE PRIMARILY IN A STATIONARY OR OFF-HIGHWAY LOW SPEED USE MAY EXHIBIT FREQUENT EXHAUST REGENERATION ATTEMPTS, DRIVE TO CLEAN MAINTENANCE MESSAGES, THE WRENCH LIGHT ON AND/OR DIAGNOSTIC TROUBLE CODE (DTC) P2459 FOR FREQUENT REGENERATION. IF REGENERATION ATTEMPTS ARE UNSUCCESSFUL, DTC P2463 MAY SET AS A RESULT OF SOOT ACCUMULATION IN THE DIESEL PARTICULATE FILTER (DPF). VEHICLES OPERATED IN THIS MANNER MAY NOT EASILY ALLOW FOR NORMAL EXHAUST REGENERATION AND MAY BENEFIT FROM OCR CAPABILITY SO THE UNIT CAN PERFORM COMPLETE REGENERATION CYCLES IN A STATIONARY SETTING. FOLLOW THE SERVICE PROCEDURE STEPS TO CORRECT THE CONDITION.
