Passive Anti-Theft System

INSTRUMENT CLUSTER (IC) DIAGNOSTIC TROUBLE CODE (DTC) LIST

DTC	Description	Action
B1015	CEI Unconfigured	The Instrument Cluster (IC) (Configurable Engine Immobilizer (CEI)) was not locked after being configured for Passive Anti-Theft System (PATS) at the assembly plant or the Cluster Service Center. After the mileage limit was reached, it self-locked. This DTC may not be able to be erased. INSTALL a new IC. REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES . PROGRAM the PATS keys into the new IC. REFER to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT . RESET the parameters in the IC and the PCM. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET . CYCLE the ignition. REPEAT the self-test.
B1213	Anti-Theft Number of Programmed Keys is Below Minimum	If DTCs B1600, B1601, B1602, B1681 or B2103 are present, they must be addressed first. If DTC B1213 is the only DTC present, PROGRAM additional keys. REFER to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
B1342	ECU is Faulted	CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. If DTC B1342 is retrieved again, INSTALL a new IC. REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES . CYCLE the ignition. REPEAT the self-test.
B1600	PATS Ignition Key Transponder Signal is Not Received	GO to PINPOINT TEST B .
B1601	PATS Received Incorrect Key-Code From Ignition Key Transponder	GO to PINPOINT TEST C .
B1602	PATS Received Invalid Format of Key-Code From Ignition Key Transponder	GO to PINPOINT TEST D .
B160A	Configurable Engine Immobilizer (CEI) Setting Mismatch	The IC (CEI) was locked after being configured and does not match the CEI setting (read keys or do not read keys) it was configured for at the assembly plant or the Cluster Service Center. This DTC may not be able to be erased. INSTALL a new IC. REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES . PROGRAM the PATS keys into the new IC if the vehicle is equipped with PATS keys. REFER to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT . RESET the parameters in the IC and the PCM. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET . CYCLE the ignition. REPEAT the self-test.
B1681	PATS Transceiver Module Signal is Not Received	GO to PINPOINT TEST E .
B2103	Antenna Not Connected	GO to PINPOINT TEST A .
B2139	Data Mismatch (Receive Data Does Not Match What Was Expected)	CARRY OUT a parameter reset of the IC and PCM, then CYCLE the ignition and make an attempt to start the vehicle. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET .
B2141	NVM Configuration Failure	There is no PCM ID stored in the IC. CARRY OUT a parameter reset of the IC and PCM, then CYCLE the ignition and make an attempt to start the vehicle. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET .
B2431	Transponder Programming Failed	The ignition key was not programmed. ATTEMPT to program the key. REFER to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
U0100	Lost Communication With ECM /PCM	NOTE: If DTCs U0100 and U2510 are both present, address DTC U2510 first. GO to PINPOINT TEST G .
U2510	CAN - Invalid Data for Vehicle Security	CARRY OUT a parameter reset of the IC and the PCM and CYCLE the ignition 3-5 times, making an attempt to start the vehicle each key cycle. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
U2511	CAN - Data Mis-Match (Receive Data Does Not Match Expected)	NOTE: If DTCs U2510 and U2511 are both present, address DTC U2510 first. GO to PINPOINT TEST G .
All other DTCs	-	REFER to the Diagnostic Trouble Code (DTC) Chart in MULTIFUNCTION ELECTRONIC MODULES .

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 . 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 Wiring Diagrams Information to determine the PCM power and ground circuits.
All other DTCs	-	REFER to the ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) .
