Vehicle Preparation For OBD-II Or Monitor Repair Verification Drive Cycle
NOTE:
Vehicles equipped with Power Take Off (PTO) must have this system disengaged before proceeding. Verify by viewing the PTO PID for OFF status.
- Attach a scan tool and access the ECT, FLI, IAT PIDs:
- Verify the IAT PID is between 50-100° F (10-38°C).
- Verify the FLI PID is between 15% and 85% (only available on EVAP running loss systems).
- Warm the vehicle until the ECT PID reaches a minimum of 130°F (54° C).
- Clear all DTC's with the scan tool by pressing clear with the key on engine off. P1000 will remain. Leave the key in the ON position (do not move ignition switch to OFF position), and start the vehicle.
- Access the ON-BOARD SYSTEM READINESS menu on the scan tool to view the status of the OBD-II monitors.
- Proceed with the OBD-II drive cycle or selected monitor repair verification drive cycle. Once started, the engine must not be turned off.
