Drive Cycle Procedure: 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 is completed and 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. A scan tool can be used to observe a monitor system status, Parameter Identification (PID) values and DTC output.

NOTE: Rough road conditions may prevent certain steady state conditions and steady accelerations from validating the transmission and load related monitors. On models with Power Take-Off (PTO), disengaged PTO system before performing drive cycle.
