Readiness Drive Cycle Procedure

-- CONNECT: Scan Tool.

Step Procedure Result / Action to Take
1 Activate Monitors:
  • START: Engine and idle for 2 - 3 min.
  • Monitoring Active.
  • Executes Misfire Monitoring.
2 O2 Sensor Monitoring:
  • DRIVE: Vehicle at 45 - 55 mph for a continuous 7 minute period. Avoid stopping.
  • Executes O2 Sensor Monitoring.
  • Executes Fuel Trim Monitoring.
  • Executes EVAP Monitoring.
3 Fuel Cut-Off Monitoring:
  • ACCELERATE: Vehicle to an engine speed of 5, 000 RPM; lift off the throttle until the engine speed is around 1, 200 RPM.
  • Fuel Cut-Off Monitoring Ready.
4 Catalyst Monitoring:
  • ACCELERATE: Vehicle smoothly to 60 - 65 mph, cruise at a constant speed for 5 min.
  • Executes Catalyst Monitoring.
  • Executes O2 Sensor Monitoring.
  • Executes Fuel Trim Monitoring.
  • Executes Misfire Monitoring.
  • Executes EVAP Monitoring.
5 Secondary Air Injection, EVAP Monitoring:
  • DRIVE: Vehicle for 30 - 40 min. at a constant speed of 50 - 70 mph in high gear for 2 min with no coasting.
  • Executes Secondary Air Injection Monitoring.
  • Executes EVAP Monitoring.
  • Check the status of the readiness code.

-- If any engine monitor fails the drive cycle test. Repeat the drive cycle test until all engine monitors have successfully run through and passed.

NOTE:

When repeating the drive cycle operation for a failed evaporative or thermostat monitor, allow the engine to cool until the coolant temperature and the ambient air temperature are between 10° C and 35° C with a difference between them no greater than 4° C and then repeat the drive cycle operation.

Depending on the scan tool used, the readiness code status may be displayed as complete, passed or OK. At an ambient air temperature < 7° C, the setting of the readiness for the NOx catalytic converter test is delayed. Here the vehicle must be driven considerably longer.
