	M-MDS display	Keyless control module	B10D7:81
		PCM	P1260:00
POSSIBLE CAUSE				•  Transponder (key) malfunction •  If any of the following items are touching or near key head, signal communication between key and vehicle is negatively affected, resulting in engine not starting ―  Spare keys am6zzw00001762 ―  Keys for other vehicles equipped with an immobilizer system ―  Any metallic object ―  Any electronic device, or any credit or other card with magnetic strips •  Coil antenna installation malfunction •  Coil antenna malfunction •  Keyless control module malfunction

Diagnostic Procedure

Step	Inspection		Action
1	VERIFY COIL ANTENNA CORRECTLY INSTALLED •  Verify the installation condition of the coil antenna. •  Is the coil antenna correctly installed? (Is it not completely installed?)	Yes	Go to the next step.
		No	Install the coil antenna correctly, then go to the next step. (See COIL ANTENNA REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
2	VERIFY WHETHER KEY IS VALID OR NOT •  Using another programmed key, ignition is switched to the ON. •  If there is not another programmed key, program an additional key and ignition is switched to the ON using the programmed key. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) •  Clear DTCs using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Verify DTCs using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Are DTCs output again? ―  Keyless control module: B10D7:81 ―  PCM:P1260:00	Yes	Replace the coil antenna, then go to the next step. (See COIL ANTENNA REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
		No	Dispose of the malfunctioning key. Program a new key if necessary. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) Go to Step 4.
3	INSPECT KEYLESS CONTROL MODULE •  Using another programmed key, ignition is switched to the ON. •  Clear DTCs using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Verify DTCs using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Are DTCs output again? ―  Keyless control module: B10D7:81 ―  PCM:P1260:00	Yes	Replace the keyless control module and program the immobilizer system-related parts. (See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) Go to the next step.
		No	Go to Step 5.
4	VERIFY AFTER REPAIR •  Clear DTCs using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Verify DTCs using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Are DTCs output again? ―  Keyless control module: B10D7:81 ―  PCM:P1260:00	Yes	Inspect DTC P1260:00. (See DTC P1260:00 [L8, LF, L5].)
		No	Go to the next step.
5	VERIFY THAT NO OTHER DTCs ARE PRESENT •  Verify if other DTCs are displayed. •  Are any other DTCs output?	Yes	Perform the corresponding DTC inspection.
		No	DTC troubleshooting completed.
