PINPOINT TEST QC: On Board Diagnostic (OBD) Systems Readiness: Introduction
NOTE:
The vehicle may not have completed an OBD drive cycle. This will be indicated by the Inspection Maintenance (I/M) Readiness status not complete. In some areas, the OBD drive cycle must be completed to pass an I/M test. Refer to
ON BOARD DIAGNOSTIC (OBD) DRIVE CYCLE
.
On some vehicles, DTC P1000 may set. 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.
On vehicles that support DTC P1000, the DTC may set 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.
