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 (ABS HU/CM or 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 error
	M-MDS display	Keyless control module	B10D7:94
		PCM	P1260:00
DETECTION CONDITION				•  Key ID number data cannot be read.
POSSIBLE CAUSE				•  Using the M-MDS, perform specific module configuration, module programming, DTC inspection, or Mazda Vehicle Check-up. •  Transponder malfunction ―  There is no transponder in the key. ―  Key code is not output. •  Coil antenna malfunction •  Keyless control module malfunction •  PCM malfunction •  If any of the following items are touching or near key head, signal communication between key and vehicle is negatively affected, resulting in the engine not starting. ―  Spare keys ―  Keys for other vehicles equipped with immobilizer system ―  Any metallic object ―  Any electronic device, or any credit or other card with magnetic strips am6zzw00001762

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	VERIFY DTCs •  Clear the DTC from the keyless control module using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Verify the immobilizer system DTC using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Is the following DTC present? ―  Keyless control module: B10D7:05 ―  PCM: P1260:00	Yes	Perform the security light: 13, DTC: B10D7:05/P1260:00 inspection. (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.
2	VERIFY WHETHER THERE IS A VALID KEY •  Are there any valid keys which can start the engine other than the cause of the displayed DTC?	Yes	Go to the next step.
		No	Program an additional key referring to the immobilizer system-related parts programming, then go to the next step. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
3	VERIFY COIL ANTENNA MALFUNCTION •  Switch the ignition to ON using the valid key other than the cause of the displayed DTC. •  Clear the DTC from the keyless control module using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Verify the immobilizer system DTC using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Is the following DTC present? ―  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 and program a new key if necessary, then go to Step 6. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) Note •  To start the engine, two or more programmed keys are necessary.
4	VERIFY KEYLESS CONTROL MODULE MALFUNCTION •  Clear the DTC from the keyless control module using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Verify the immobilizer system DTC using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Is the following DTC present? ―  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 6.
5	VERIFY TROUBLESHOOTING COMPLETED •  Clear the DTC from the keyless control module using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Verify the immobilizer system DTC using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) •  Is the following DTC present? ―  Keyless control module: B10D7:94 ―  PCM: P1260:00	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [MZR 1.8, MZR 2.0, MZR 2.5].) (See PCM REMOVAL/INSTALLATION [MZR 2.0 DISI].) (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].)
		No	Go to the next step.
6	VERIFY THAT NO OTHER DTCs ARE PRESENT •  Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].)
		No	DTC troubleshooting completed.
