| P1000 | Test MB , Step 1) |
NOTE:
After each service or repair procedure has been completed, reconnect all components. Clear DTCs and repeat QUICK TEST procedures to ensure all electronic engine control systems are working properly and DTCs are no longer present.
- 1) Continuous Memory DTC P1000: Repeat Self-Test
DTC P1000 indicates operating conditions have not been satisfied for all OBD-II monitors to be run. Possible causes are:- Drive Conditions Not Satisfied
- Keep Alive Memory (KAM) Cleared
- Faulty PCM
Perform all SELF-TESTS and check for DTCs. If any DTCs other than P1000 are present, perform appropriate system test and repair as necessary. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If DTC P1000 is only DTC present, go to next step.
- 2) Perform Drive Cycle
Perform drive cycle. See DRIVE CYCLES . If DTC P1000 is now cleared, no concern is indicated at this time. If DTC P1000 is still present, go to next step. - 3) Verify Certain Operating Conditions Have Been Satisfied
Ensure the following conditions are met:- Using scan tool, access EOT, IVPWR and GPC PIDs from PID/DATA MONITOR & RECORD menu. If engine is started and EOT PID value is less than 86°F (30°C) on Econoline or less than 131°F (55°C) on Excursion and F250-750, IVPWR value must be 11.5-14.0 volts until GPC PID value is zero percent.
- Using scan tool, monitor MFDES PID reading with engine speed (RPM) under full load. MFDES PID reading must be more than 37 milligrams/stroke for 12 seconds or more with engine speed at more than 2300 RPM.
- Using scan tool, monitor MFDES PID reading with engine at normal operating temperature and at idle. MFDES PID value must be less than 12 milligrams/stroke for 12 seconds or more.
With all conditions met in this step, if DTC P1000 is cleared, no concern is indicated at this time. If DTC P1000 is still present, determine DTC clearing fault. Perform all engine performance diagnostic procedures. See ENGINE PERFORMANCE DIAGNOSTIC PROCEDURES in SYSTEM & COMPONENT TESTING - 7.3L DIESEL article.
NOTE:
If power to PCM is disconnected, DTC P1000 will be set until OBD-II monitors have been run completely. For additional information on OBD-II monitors, see DRIVE CYCLES .
