SECURITY LIGHT: 13, DTC: B10D7:94/P1260:00 [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)]

id09021d356000

Note

•  If the BCM configuration and DTC inspection for the following modules are performed, the keyless control module will be temporarily unable to read the key code due to the signal from the M-MDS. As a result, DTC B10D7:94 is stored in the keyless control module.

―  KOEO/KOER self test (PCM)

―  ABS (DSC HU/CM)

―  BCM

―  EPS (EPS control module)

―  RCM (SAS control module)

―  RKE (keyless control module)

―  FFH (water heater unit)

DTC	Security light flashing pattern		13	Key ID number data cannot be read
	M-MDS display	Keyless control module	B10D7:94
		PCM	P1260:00
POSSIBLE CAUSE				•  There is no transponder in the key •  Transponder malfunction (key code is not output) •  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 immobilizer system ―  Any metallic object ―  Any electronic device, or any credit or other card with magnetic strips •  Coil antenna malfunction •  Keyless control module malfunction •  Using the M-MDS, perform specific module configuration, module programming, DTC inspection, or Mazda Vehicle Check-up.

Diagnostic Procedure

Step	Inspection		Action
1	VERIFY DTCs •  Clear DTCs using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Insert a programmed ignition key into the key slot. •  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: B10D7:94 ―  PCM:P1260:00	Yes	Go to Step 3.
		No	Go to the next step.
2	VERIFY DTCs •  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)].) •  Is the DTC displayed again? ―  Keyless control module: B10D7:05 ―  PCM:P1260:00	Yes	Security light: 13, M-MDS: Inspect B10D7:05/P1260:00. (See SECURITY LIGHT: 13, DTC: B10D7:05/P1260:00 [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].)
		No	Go to the next step.
3	VERIFY WHETHER KEY IS VALID OR NOT •  Are there any keys with which the engine can be started, other than the key that is a cause of the displayed DTC?	Yes	Go to Step 5.
		No	Go to the next step.
4	VERIFY WHETHER MALFUNCTION IS IN KEY OR COIL ANTENNA •  Program an additional key. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) •  Insert a programmed ignition key into the key slot and switch the ignition to 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: B10D7:94 ―  PCM:P1260:00	Yes	Replace the coil antenna, then go to Step 6. (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 COIL ANTENNA REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) Go to Step 8.
5	VERIFY WHETHER MALFUNCTION IS IN KEY OR COIL ANTENNA •  Switch the ignition to off. •  Using another valid 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: B10D7:94 ―  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 COIL ANTENNA REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) Go to Step 8.
6	INSPECT KEYLESS CONTROL MODULE •  Switch the ignition to off. •  Using the 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: B10D7:94 ―  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 8.
7	VERIFY AFTER REPAIR •  Clear DTCs using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Insert a programmed ignition key into the key slot and switch the ignition to ON. •  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: B10D7:94 ―  PCM:P1260:00	Yes	Inspect DTC P1260:00. (See DTC P1260:00 [L8, LF, L5].)
		No	Go to the next step.
8	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.
