Drive Cycles: Overview
NOTE:
Strict observance of posted speed limits and attention to driving conditions are mandatory when proceeding through the drive cycle.
NOTE:
Vehicles equipped with power take off (PTO) or auxiliary idle control must have that system disengaged before the drive cycle is initiated.
The Drive Cycle Procedure is carried out to satisfy the specifications for the Society of Automotive Engineers (SAE) specification J1979. Each on board diagnostic (OBD) monitor must run during the drive cycle.
