Anti-Theft - Without Intelligent Access (IA)

INSTRUMENT PANEL CLUSTER (IPC) DIAGNOSTIC TROUBLE CODE (DTC) LIST

DTC	Description	Action
B109E:42	Remote Keyless Entry: General Memory Failure	The Smart Junction Box (SJB) has 4 Integrated Keyhead Transmitters (IKTs) stored in memory and cannot program any more IKTs into the SJB memory. REFER to PRINCIPLES OF OPERATION to determine this is normal operation for this system.
B10D5:13	PATS Antenna: Circuit Open	There has been a Passive Anti-Theft System (PATS) transceiver antenna failure. GO to PINPOINT TEST A .
B10D7:05	PATS Key: System Programming Failures	There was a failure in key programming and the key was not programmed. ATTEMPT to program the key. REFER to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT - WITHOUT INTELLIGENT ACCESS (IA) . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. If the concern is still present, GO to PINPOINT TEST I .
B10D7:51	PATS Key: Not Programmed	There is an unprogrammed PATS key. GO to PINPOINT TEST C .
B10D7:87	PATS Key: Missing Message	No PATS key has been read by the IPC. GO to PINPOINT TEST B .
B10D7:8F	PATS Key: Erratic	Only a partial PATS key was read. GO to PINPOINT TEST D .
B10D8:00	PATS Key Less Than Minimum Programmed: No Sub Type Information	If DTCs B10D7:87, B10D7:51, B10D7:8F, B10D9:87 and B10D5:13 are present, they must be addressed first. If DTC B10D8:00 is the only DTC present, PROGRAM additional keys. REFER to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT - WITHOUT INTELLIGENT ACCESS (IA) . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
B10D9:87	PATS Transponder: Missing Message	The Instrument Panel Cluster (IPC) did not receive the PATS transceiver signal. GO to PINPOINT TEST E .
B10DA:51	PATS PCM Identifier: Not Programmed	There is no PCM ID stored in the IPC. CARRY OUT a parameter reset of the IPC and the PCM, then CYCLE the ignition and make an attempt to start the vehicle. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET - WITHOUT INTELLIGENT ACCESS (IA) . CLEAR the DTCs. REPEAT the self-test.
B10DA:61	PATS PCM Identifier: Signal Calculation Failure	CARRY OUT a parameter reset of the IPC 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 - WITHOUT INTELLIGENT ACCESS (IA) . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
B10DA:86	PATS PCM Identifier: Signal Invalid	NOTE: If DTCs B10DA:61 and B10DA:86 are both present, address DTC B10DA:61 first. GO to PINPOINT TEST G .
U0100:00	Lost Communication With ECM/PCM "A": No Sub Type Information	NOTE: If DTCs U0100:00 and B10DA:61 are both present, address DTC B10DA:61 first. GO to PINPOINT TEST G .
All other DTCs	-	REFER to the Diagnostic Trouble Code (DTC) Chart in MULTIFUNCTION ELECTRONIC MODULE Article.

PCM DIAGNOSTIC TROUBLE CODE (DTC) LIST

DTC	Description	Action
P1260	Theft Detected, Vehicle Immobilized	If there are any Passive Anti-Theft System (PATS) DTCs present in the Instrument Panel Cluster (IPC), ADDRESS them first. This DTC may also indicate a Controller Area Network (CAN) or parameter reset issue. Make sure to verify if there are any communication issues/DTCs with any modules. REFER to MODULE COMMUNICATIONS NETWORK Article. If DTC P1260 is the only DTC present, there may be a parameter reset, power or ground concern with the PCM. For the parameter reset issue, REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET - WITHOUT INTELLIGENT ACCESS (IA) . For the PCM power and grounds issue, 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.
P1602	Immobilizer/ECM Communication Error	NOTE: If IPC DTC B10DA:61 is also present, address IPC DTC B10DA:61 first. GO to PINPOINT TEST G .
P1622	Immobilizer ID Does Not Match	CARRY OUT a parameter reset of the IPC 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 - WITHOUT INTELLIGENT ACCESS (IA) . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
