DRIVE CYCLE GUIDE<\/h1>

Readiness guidance for Chrysler, Dodge, Jeep, and Ram gasoline and diesel vehicles, with monitor-specific and regeneration cautions.<\/p><\/div><\/section>\n

Important:<\/strong> Drive cycles vary by model year, engine, transmission, fuel type, software calibration, and the monitor that is incomplete. Use this as practical guidance\u2014not a substitute for the exact service procedure. Obey traffic laws and never watch a scan tool while driving.<\/div><\/section>\n

START WITH THE INCOMPLETE MONITOR<\/h2>

Chrysler, Dodge, Jeep, and Ram procedures are usually monitor-specific. Stellantis service information uses scan-tool readiness status to identify what has not completed, then lists the operating conditions needed for that monitor.<\/p>

Common gasoline readiness pattern<\/h2>
  1. Begin with a cold engine if the monitor requires a cold soak.<\/li>
  2. Start without unnecessary throttle and allow a short idle.<\/li>
  3. Use gentle acceleration and normal city driving until fully warm.<\/li>
  4. Maintain a steady 40\u201360 mph cruise when safe and legal.<\/li>
  5. Include safe closed-throttle deceleration and normal idle periods.<\/li>
  6. Complete more than one trip if the enabling conditions do not occur together.<\/li><\/ol>

    EVAP, catalyst, and oxygen-sensor monitors<\/h2>

    EVAP may require a mid-range fuel level, acceptable temperature, a long soak, and a key-off leak test. Catalyst and oxygen-sensor monitors generally need full operating temperature, stable fuel control, steady cruise, and deceleration without related faults.<\/p>

    Ram and Jeep diesel readiness<\/h2>

    Diesel vehicles add DPF, NMHC catalyst, SCR\/NOx, exhaust-gas-sensor, boost-pressure, EGR, and fuel-system monitors. Stellantis guidance notes that a vehicle may require extended driving in varied conditions after the PCM is flashed, replaced, or cleared.<\/p>
