NOTE:
Diagnostic Trouble Code (DTC) P1000 indicates that all the OBD monitors have not yet been successfully tested. In some areas, this DTC must be cleared to pass an inspection/maintenance 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 inspection/maintenance station. The amount of driving required varies with individual driving patterns. To complete this requirement in the shortest amount of time, refer to DRIVE CYCLES
.
It is not necessary to clear DTC P1000 from the PCM by driving the vehicle unless it is requested by the customer to pass an inspection/maintenance test .
The only way a DTC P1000 can be removed from memory is when all the OBD monitors are successfully completed .

- An OBD monitor failure had 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 cannot be cleared from the PCM when:
- The vehicle has a Power Take OFF (PTO) and the circuit is shorted to VPWR or B+ or the PTO is on during the testing.
