Anti-Theft - With Intelligent Access (IA)

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 Remote Function Actuator (RFA) module, ADDRESS them first. This DTC may also indicate a Controller Area Network (CAN) or parameter reset issue or a PCM power or ground issue. Make sure to verify if there are any communication issues/DTCs with any modules. For the CAN issue, REFER to MODULE COMMUNICATIONS NETWORK Article. If DTC P1260 is the only DTC present, there may be a parameter reset issue, power or ground issue with the PCM. For the parameter reset issue, REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET - WITH INTELLIGENT ACCESS (IA) . For the PCM power or ground 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 RFA module DTC B10DA:61 is also present, address RFA module DTC B10DA:61 first. GO to PINPOINT TEST O .
P1622	Immobilizer ID Does Not Match	CARRY OUT a parameter reset of the RFA module 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 - WITH INTELLIGENT ACCESS (IA) . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
All other DTCs	-	REFER to the INTRODUCTION - GASOLINE MODELS Article.

B10C9:01	Interior Front Antenna: General Electrical Failure	GO to PINPOINT TEST J .
B10C9:13	Interior Front Antenna: Circuit Open	GO to PINPOINT TEST J .
B10D7:05	PATS Key: System Programming Failure	GO to PINPOINT TEST K .
B10D7:31	PATS Key: No Signal	This DTC sets during an Remote Function Actuator (RFA) module self-test if 2 programmed Intelligent Access (IA) keys are not detected inside the vehicle. Check each IA key individually to see if it operates the vehicle. If an IA key does not operate the vehicle, program that key. Refer to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT - WITH INTELLIGENT ACCESS (IA) . If 2 programmed IA keys are not present inside the vehicle, disregard this DTC.
B10D8:51	Passive Anti-Theft System (PATS) Key Less Than Minimum Programmed: Not Programmed	If other PATS DTCs are present, address them first. If DTC B10D8:51 is the only DTC present, PROGRAM additional keys (minimum of 2 keys must be programmed). REFER to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT - WITH INTELLIGENT ACCESS (IA) . CLEAR the DTCs. REPEAT the self-test.
B10D9:11	PATS Transponder: Circuit Short To Ground	GO to PINPOINT TEST M .
B10D9:12	PATS Transponder: Circuit Short To Battery	GO to PINPOINT TEST M .
B10D9:31	PATS Transponder: No Signal	GO to PINPOINT TEST M .
B10D9:87	PATS Transponder: Missing Message	GO to PINPOINT TEST M .
B10DA:51	PATS PCM Identifier: Not Programmed	There is no PCM ID stored in the RFA module. CARRY OUT a parameter reset of the RFA module and the PCM, then CYCLE the ignition and make an attempt to start the vehicle. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET - WITH INTELLIGENT ACCESS (IA) . CLEAR the DTCs. REPEAT the self-test.
B10DA:61	PATS PCM Identifier: Signal Calculation Failure	There is an incorrect PCM ID stored in the RFA module. CARRY OUT a parameter reset of the RFA module and the PCM, then CYCLE the ignition and make an attempt to start the vehicle. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET - WITH INTELLIGENT ACCESS (IA) . CLEAR the DTCs. REPEAT the self-test.
B10DA:86	PATS PCM Identifier: Signal Invalid	There is an issue with the PCM ID stored in the RFA module. CARRY OUT a parameter reset of the RFA module and the PCM, then CYCLE the ignition and make an attempt to start the vehicle. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET - WITH INTELLIGENT ACCESS (IA) . CLEAR the DTCs. REPEAT the self-test.
B125D:11	Ignition Run LED: Circuit Short To Ground	GO to PINPOINT TEST P .
B125D:15	Ignition Run LED: Circuit Short To Battery or Open	GO to PINPOINT TEST P .
U0100:87	Lost Communication With ECM/PCM "A": Missing Message	NOTE: If DTC B10DA:51, B10DA:61 or B10DA:86 is present, address DTC B10DA:51, B10DA:61 or B10DA:86 first. GO to PINPOINT TEST Q .
U201F:31	External Receiver: No Signal	GO to PINPOINT TEST N .
