PCM DIAGNOSTIC TROUBLE CODE (DTC) LIST

DTC	Description	Action
P1260	Theft Detected, Vehicle Immobilized	NOTE: This DTC usually accompanies Passive Anti-Theft System (PATS) DTCs in the Instrument Cluster (IC). If the vehicle is not equipped with PATS , this PCM DTC can indicate the parameters in the IC and the PCM need to be reset or a power or ground issue with the PCM. This PCM DTC can set in vehicles with or without PATS . CLEAR the DTCs. REPEAT the self-test. If there are any PATS DTCs present in the IC , ADDRESS them first. This DTC may also indicate a Controller Area Network (CAN) concern or a parameter reset concern. MAKE SURE to verify if there are any communication concerns/DTCs with any modules. REFER to MODULE COMMUNICATIONS NETWORK article. If DTC P1260 is the only DTC present, there may be a parameter reset concern or a power or ground concern with the PCM. Even if the vehicle does not have PATS , it still has parameters that may need to be reset. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET to reset the parameters. If necessary, CHECK the powers and grounds to the PCM. REFER to the SYSTEM WIRING DIAGRAMS article to determine the PCM power and ground circuits.
