2.2 Generic OBD-II Drive Cycle

For each monitoring strategy, the OBD-II drive cycle to be used is stated. The purpose of the drive cycle is to run the onboard diagnostics monitoring strategy under consideration. The number of drive cycles that must be completed in order to illuminate the MIL is given in the Monitoring Operation table for each monitoring strategy. The drive cycle should be performed after any Diagnostic Trouble Codes (DTCs) have been erased from the ECM's memory, or after the battery has been disconnected.
