EVAP Monitor Repair Verification Drive Cycle

NOTE: 8 hour 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.

Ensure vehicle inlet air temperature (IAT) PID is 14-102°F (-10-38°C) and fuel level (FLI) PID is 15-85 percent. monitor period will be during 4-10 minutes after engine is started. System test takes at least 30 seconds during this time. If time exceeds 10 minutes, turn ignition off and restart test. Cold soak vehicle for 8 hours. Connect scan tool. Turn all accessories off. Start engine. Accelerate to 35-65 MPH within 4 minutes. Drive vehicle at 35-65 MPH 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.
