DTC B10E7:16 [Advanced Keyless Entry And Push Button Start System]

DESCRIPTION	Low voltage in IG1 monitor input circuit
DETECTION CONDITION	IG1 monitor voltage is less than 2.5 V for 1 s when the ignition switch is ON.
POSSIBLE CAUSE	Relay block connector or terminals malfunction Keyless control module connector or terminals malfunction Open circuit or short to ground in IG1 monitor input circuit Short to ground in wiring harness between relay block terminal 1B and keyless control module terminal 2A METER 15 A fuse malfunction Open circuit in wiring harness between relay block terminal 1B and keyless control module terminal 2A Relay block malfunction Keyless control module malfunction

DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	VERIFY RELATED STORED DTC Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS. (See DTC INSPECTION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ). Is the DTC B10E7:11 also present?	Yes	Go to the applicable DTC inspection. (See DTC B10E7:11 [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ).
1		No	Go to the next step.
2	INSPECT RELAY BLOCK CONNECTOR AND TERMINALS Switch the ignition to off. Disconnect the negative battery cable. Disconnect the relay block 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 6.
2		No	Go to the next step.
3	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 6.
3		No	Go to the next step.
4	INSPECT IG1 MONITOR INPUT CIRCUIT FOR OPEN CIRCUIT OR SHORT TO GROUND Relay block and keyless control module connectors are disconnected. Reconnect the relay block connector. Reconnect the negative battery cable. Switch the ignition to ON. Measure the voltage at the following terminal (wiring harness-side): Keyless control module terminal 2A Is the voltage B+?	Yes	Go to the next step.
4		No	Inspect the METER 15 A fuse. If the fuse is melt: Repair or replace the wiring harness for a possible short to ground. Replace the fuse. If the fuse is deterioration: Replace the fuse. If the fuse is normal: Repair or replace the wiring harness for a possible open circuit. Go to Step 6.
5	INSPECT RELAY BLOCK Switch the ignition to off. Inspect the relay block. (See RELAY BLOCK INSPECTION [WITH ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ). Is there any malfunction?	Yes	Replace the relay block, then go to the next step. (See RELAY BLOCK REMOVAL/INSTALLATION [WITH ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ).
5		No	Go to the next step.
6	VERIFY TROUBLESHOOTING COMPLETED Make sure to reconnect the disconnected connectors. Reconnect the negative battery cable. Clear the DTC from the keyless control module using the M-MDS. (See CLEARING DTC [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ). Switch the ignition to off, then to ON. Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS. (See DTC INSPECTION [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 ).
6		No	Go to the next step.
7	VERIFY THAT NO OTHER DTCs ARE PRESENT Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ).
7		No	DTC troubleshooting completed.
