Security Light: Not Illuminated, DTC B10E6:11/-[Immobilizer System (Advanced Keyless Entry And Push Button Start System)]

DTC	Security light flashing pattern		-	Short to ground in coil antenna power supply circuit
	M-MDS display	Keyless control module	B10E6:11
	M-MDS display	PCM	-
DETECTION CONDITION				Coil antenna power supply circuit voltage is lower than the specification when the circuit is active.
POSSIBLE CAUSE				Coil antenna connector or terminals malfunction Keyless control module connector or terminals malfunction Short to ground in wiring harness between the following terminals: Coil antenna terminal D-Keyless control module terminal 3M Coil antenna malfunction Keyless control module malfunction

DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	INSPECT COIL ANTENNA CONNECTOR AND TERMINALS Switch the ignition to off. Disconnect the negative battery cable. Disconnect the coil antenna connector. Inspect the connector and terminals (corrosion, damage, pin disconnection). Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 5.
1		No	Go to the next step.
2	INSPECT KEYLESS CONTROL MODULE CONNECTOR AND TERMINALS Disconnect the keyless control module connector. Inspect the connector and terminals (corrosion, damage, pin disconnection). Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 5.
2		No	Go to the next step.
3	INSPECT COIL ANTENNA POWER SUPPLY CIRCUIT FOR SHORT TO GROUND Coil antenna and keyless control module connectors are disconnected. Inspect for continuity between the following terminal (wiring harness-side) and body ground: Coil antenna terminal D Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, then go to Step 5.
3		No	Go to the next step.
4	VERIFY COIL ANTENNA MALFUNCTION Make sure to reconnect the disconnected connectors. Reconnect the negative battery cable. Clear the DTC from the keyless control module and PCM using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)] ). (See AFTER REPAIR PROCEDURE [LF, L5] ). (See AFTER REPAIR PROCEDURE [L3 WITH TC] ). Perform the immobilizer system DTC inspection using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)] ). Is the same DTC present?	Yes	Replace the coil antenna, then go to the next step. (See COIL ANTENNA REMOVAL/INSTALLATION ).
4		No	Go to Step 6.
5	VERIFY TROUBLESHOOTING COMPLETED Make sure to reconnect the disconnected connectors. Reconnect the negative battery cable. Clear the DTC from the keyless control module and PCM using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)] ). (See AFTER REPAIR PROCEDURE [LF, L5] ). (See AFTER REPAIR PROCEDURE [L3 WITH TC] ). Perform the immobilizer system DTC inspection using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)] ). Is the same DTC present?	Yes	Replace the keyless control module, then go to the next step. (See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION ).
5		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)] ).
6		No	DTC troubleshooting completed.
