Error Code P1000
Low Issue
DTC Code P1000 indicates that the On-Board Diagnostic (OBD) System Readiness Test is not complete. This code is stored when any OBD monitors fail to perform their full diagnostic check during the OBD Drive Cycle.
What symptoms indicate Error Code P1000?
- Engine Light ON: The engine light or service engine soon warning light illuminates on the dashboard. This indicates that the On Board Diagnostic (OBD) system has not completed its readiness tests. This can occur after the battery has been disconnected or the diagnostic trouble codes have been cleared.
What causes OBD code Error Code P1000?
- The vehicle is new from the factory, and the OBD system has not yet completed its initial drive cycle.
- The battery or Powertrain Control Module (PCM) was recently disconnected, interrupting the OBD system's readiness tests.
- An OBD monitor failure occurred before the completion of an OBD drive cycle, preventing the readiness tests from finalizing.
- PCM Diagnostic Trouble Codes (DTC) were recently cleared with a scan tool, resetting the OBD system and requiring a new drive cycle to complete readiness tests.
How to fix OBD code Error Code P1000?
- Verify Battery Connection: Ensure the battery is properly connected and has not been recently disconnected. A recent disconnection can trigger the P1000 code.
- Check for Cleared Codes: Determine if any diagnostic trouble codes have been recently cleared. Clearing codes can interrupt the diagnostic cycle, leading to a P1000 code.
- Inspect for Recent Towing: Confirm if the vehicle has been towed recently. Towing can prevent the completion of the diagnostic cycle, resulting in a P1000 code.
- Drive Cycle Completion: Drive the vehicle under various conditions to allow the PCM to complete its diagnostic cycle. This typically involves a combination of city and highway driving.
- Monitor Readiness Status: Use an OBD-II scanner to monitor the readiness status of the vehicle. Ensure all monitors are set to 'Ready' to confirm the completion of the diagnostic cycle.
