SECURITY LIGHT: 15, DTC: B10D7:51/P1260:00 [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)]

id0902e5356700

DTC	Security light flashing pattern		15	Instrument cluster has detected unprogrammed key ID number.
	M-MDS display	Instrument cluster	B10D7:51
		PCM	P1260:00
POSSIBLE CAUSE				•  No keys have been programmed after replacing instrument cluster. •  Unprogrammed key used •  Attempt made to program a ninth key •  Instrument cluster malfunction

Diagnostic Procedure

Step	Inspection		Action
1	VERIFY NUMBER OF PROGRAMMED KEYS •  Using the M-MDS, perform the PID/data monitor inspection and verify the programmed keys. (See PID/DATA MONITOR INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) ―  NUMKEYS (See PID/DATA MONITOR TABLE [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) •  Are one or more keys programmed?	Yes	Go to the next step.
		No	Go to Step 3.
2	VERIFY NUMBER OF PROGRAMMED KEYS •  Using the M-MDS, perform the PID/data monitor inspection and verify the programmed keys. (See PID/DATA MONITOR INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) ―  NUMKEYS (See PID/DATA MONITOR TABLE [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) •  Are eight keys programmed?	Yes	Erase the key ID number, then go to the next step. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [KEYLESS ENTRY SYSTEM].)
		No	Go to the next step.
3	INSPECT INSTRUMENT CLUSTER •  Program the key ID number. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [KEYLESS ENTRY SYSTEM].) Note •  Two or more keys need to be programmed to start the engine. •  Using the programmed key, turn the ignition switch to the ON position. •  Clear DTCs using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) •  Verify DTCs using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) •  Are DTCs output again? ―  Instrument cluster: B10D7:51 ―  PCM:P1260:00	Yes	•  Replace the instrument cluster and program the immobilizer system-related parts. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.) (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [KEYLESS ENTRY 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 (KEYLESS ENTRY SYSTEM)].) •  Verify DTCs using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) •  Are DTCs output again? ―  Instrument cluster: B10D7:51 ―  PCM:P1260:00	Yes	Inspect DTC P1260:00. (See DTC P1260:00 [ZJ, ZY].)
		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.
