OBD-II Drive Mode Description
OBD-II drive mode is a pattern of driving in which the Powertrain Control Module (PCM) will execute the following OBD-II diagnostic monitors:
- EGR system.
- Oxygen sensor and oxygen sensor heater.
- Catalytic converter.
- Fuel, misfire and evaporative emission control system.
DO NOT disconnect battery during and after drive mode. Disconnecting battery will reset memory. Drive mode can be used to cause a DTC to set if a fault is present or to verify that a DTC will not return after a repair has been completed.
