1996-03 7.3L Diesel: Description

Primary function of drive cycle procedure is to clear DTC P1000 and to satisfy specifications for SAE J1979. Each OBD-II monitor must run during drive cycle.

If drive cycle has been completed and DTC P1000 is not cleared, repeat entire drive cycle. If a particular step is interrupted, repeat drive mode. If drive cycle is interrupted with a key-off, only drive modes that were incomplete must be run.

CAUTION: Strict observance of posted speed limits and attention to driving conditions are mandatory when proceeding through the drive cycle.

Rough road conditions may prevent certain steady state conditions and steady accelerations from validating the transmission- and load-related monitors.

Vehicles equipped with Power Take-Off (PTO) must have that system disengaged before the OBD II drive cycle is initiated.
