JAGUAR FAULT Code p1000

OBD SYSTEM READINESS – ENGINE MANAGEMENT

Jaguar P1000 Fault code

P1000 is a very common Diagnostic Test Code (DTC) and can be indicated after maintenance has been carried out. This is not necesarily an indication of a problem, The service engineer may have cleared fault codes, after repair or rectification of a problem. If they have, code P1000 will be present, it can not be cleared by normal means, the ECU will clear the code when all engine test cycles have been completed.

  Jaguar Fault code P1000 will NOT illuminate the Jaguar Check Engine
  Light (MIL light), however it will be indicated on a DTC Reader.

If your MIL light   comes back on again after having a fault repaired it is a very good indication that the original fault remains or that a new fault has shown up. Read the DTC fault code to determine the cause of the new fault.

If the Diagnosis test Code P1000 remains flagged on the DTC Reader, after DTCs have been cleared, but the MIL indicator is not indicating a problem it is likely that engine management OBD diagnostic monitor drive cycles HAVE NOT BEEN COMPLETED.

Jaguar P1111 Fault code

If DTC P1111 is flagged after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles HAVE BEEN COMPLETED.

Every time you start the car and go through a complete drive cycle (10,000 revolutions of the motor and the motor up to temp), it is logged. after 5 complete drive cycles, the next starting of the engine, the check engine light will go out. If a further problem is sensed by the computer, the process will repeat.

OBD DIAGNOSTIC MONITORS

The Engine Management and Transmission Control systems are continuously checked during vehicle operation by the Engine Control Module (ECM) and Transmission Control Module (TCM) on-board diagnostic (OBD) facilities.

Powertrain OBD incorporates six diagnostic monitors. Each monitor has an associated group of DTCs. The diagnostic monitors will complete the diagnostic test(s) if a specified service “drive cycle” is carried out.

DIAGNOSTIC MONITORS DRIVE CYCLES

To ensure that an OBD Monitor drive cycle is completed (P1000 indication) and that all or specific components have been checked by completing a specified drive cycle. Click on the OBD area above for details, of the specified "drive cycle".
