Verification Drive Cycle

NOTE: 8 hour cold soak time may be shortened by 3 hours depending on conditions. If soak period is shortened, PCM may detect a malfunction even after repairs. This may happen under warm or hot conditions.

Cold soak vehicle for 8 hours before performing EVAP test. Connect scan tool. Turn all accessories off. Start engine. Accelerate to 40 MPH within 20 seconds. Drive vehicle at 35-45 MPH for 5.5 minutes. Accelerate to 50-60 MPH within 10 seconds and remain at that speed for at least 2 minutes. Stop vehicle and allow to idle for 20 seconds. Using scan tool, check drive mode completion status. If test is not complete, repeat test from engine start. If test is complete, check test results. If results are okay, ensure no DTCs are present. If results are not okay, repairs are not complete.

To bypass 8 hour soak time, cool fuel tank as much as possible. Connect scan tool. Access CLEAR DIAGNOSTIC CODES. Press TRIGGER to reset timer. Leave ignition on. Perform drive mode test.
