Pinpoint Test QC: DTC P1000: On-Board Diagnostic (OBD) Systems Readiness Test Not Complete: Introduction
NOTE:
Diagnostic trouble code (DTC) P1000 indicates that all of the OBD monitors have not yet been successfully tested. In some areas, this DTC must be cleared to pass an inspection/maintenance (I/M) test. The customer should be informed that the law specifies additional city and highway driving must be done to complete the check of the OBD system. This additional driving must occur before the vehicle is tested at the I/M station. The amount of driving required varies with individual driving patterns. To complete this requirement in the shortest amount of time, refer to
ON BOARD DIAGNOSTIC (OBD) DRIVE CYCLE
.
It is not necessary to clear DTC P1000 from the powertrain control module (PCM) by driving the vehicle, unless requested by the customer, to pass an I/M test.
The only way DTC P1000 can be removed from memory is when all the OBD monitors are successfully completed.
DTC P1000 is set by the PCM under any of the following conditions.
- The vehicle is new from the factory and has not yet completed an OBD drive cycle.
- The battery or PCM is disconnected.
- An OBD monitor concern occurred before completion of an OBD drive cycle.
- The PCM DTCs have been cleared with a scan tool as part of a repair process.
- The PCM has been flashed and the vehicle has not yet completed an OBD drive cycle.
- DTC P1000 may not clear if the vehicle is equipped with a power take off (PTO) and the PTO is engaged or damaged.
