OBD-II Drive Cycle Procedures

  1. HEGO Monitor Procedure

    To activate HEGO monitor, drive vehicle at 40 MPH for at least 60 seconds.

  2. EVAP Monitor Procedure

    To activate EVAP monitor when IAT PID is within 40-100°F (4-38°C), drive vehicle at 45-65 MPH for 10 minutes. Avoid sharp turns and hills. TP MODE PID should not exceed Part Throttle (PT), EVAPDC PID must be more than 75 percent, and FLI PID must be 15-85 percent.

  3. SEC AIR/Comprehensive Component Monitor Engine Procedure

    To activate ISC portion of Comprehensive Component Monitor (CCM), bring vehicle to a stop. Allow engine to idle with transmission in Drive (A/T) or Neutral (M/T) for 2 minutes.

  4. Pending Code Check & EVAP Monitor "Bypass" Check

    This procedure is used to determine if a pending code is preventing DTC P1000 from being cleared. Using scan tool, check for pending codes. If DTCs are present, perform normal repair procedures for any pending code concern. If no DTCs are present, repeat any incomplete monitor procedure. If EVAP monitor is not complete and IAT is not within 40-100°F (4-38°C), or altitude is greater than 8000 feet, perform  EVAP Monitor "Bypass" Procedure.

  5. EVAP Monitor "Bypass" Procedure

    Leave scan tool connected and allow vehicle to sit overnight. Vehicle must be parked for more than 8 hours. Perform step  4 under OBD-II DRIVE CYCLE PREPARATION and  PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK. DO NOT repeat step 1)  under OBD-II DRIVE CYCLE PREPARATION.
