DTC P1260: - Theft Detected, Vehicle Immobilized

DTC P1260: - THEFT DETECTED, VEHICLE IMMOBILIZED

Description:  This DTC can be set if the passive anti-theft system (PATS) has determined a theft condition existed and the engine is disabled or an engine start was attempted using a non-PATS key. This DTC is a good indicator to check the PATS for DTCs.
This DTC can also be set when a new instrument cluster (IC) or powertrain control module (PCM) is installed without correctly programming either module even if the vehicle is not equipped with PATS.
Possible Causes: 
  • Incorrectly programmed PCM
  • Incorrectly programmed IC
  • Previous theft condition
  • Anti-theft system concern
Diagnostic Aids:  Theft indicator flashing rapidly or on solid when the ignition is in the ON position. Check the anti-theft system for DTCs. Refer to the ANTI-THEFT - PERIMETER , Diagnostic Trouble Code (DTC) Charts to continue diagnosis.
If a new IC or PCM is installed without correctly programming either module, the parameters must be reset in both modules. Refer to the ANTI-THEFT - PERIMETER , Passive Anti-Theft System (PATS) Parameter Reset, to continue diagnosis.
