DTC P0560:16 [Advanced Keyless Entry And Push Button Start System]

DESCRIPTION	Low voltage in power supply circuit (+B3)
DETECTION CONDITION	Keyless control module power supply circuit (+B3) voltage is less than 8.5 V for 5 s.
POSSIBLE CAUSE	Charging system malfunction PCM DTC is stored Battery malfunction Generator malfunction Keyless control module connector or terminals malfunction Open circuit or short to ground in keyless control module power supply circuit Short to ground in wiring harness between battery positive terminal and keyless control module terminal 1A ESCL 15 A fuse malfunction Open circuit in wiring harness between battery positive terminal and keyless control module terminal 1A Keyless control module malfunction

DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	CONFIRM PCM DTC Perform the PCM DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [LF, L5] ). (See ON-BOARD DIAGNOSTIC TEST [L3 WITH TC] ). Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [LF, L5] ). (See DTC TABLE [L3 WITH TC] ).
1		No	Go to the next step.
2	INSPECT BATTERY Inspect the battery. (See BATTERY INSPECTION [LF, L5] ). (See BATTERY INSPECTION [L3 WITH TC] ). Is there any malfunction?	Yes	Recharge or replace the battery, then go to Step 6. (See BATTERY RECHARGING [LF, L5] ). (See BATTERY RECHARGING [L3 WITH TC] ). (See BATTERY REMOVAL/INSTALLATION [LF, L5] ). (See BATTERY REMOVAL/INSTALLATION [L3 WITH TC] ).
2		No	Go to the next step.
3	INSPECT GENERATOR Inspect the generator. (See GENERATOR INSPECTION [LF, L5] ). (See GENERATOR INSPECTION [L3 WITH TC] ). Is there any malfunction?	Yes	Replace the generator, then go to Step 6. (See GENERATOR REMOVAL/INSTALLATION [LF, L5] ). (See GENERATOR REMOVAL/INSTALLATION [L3 WITH TC] ).
3		No	Go to the next step.
4	INSPECT KEYLESS CONTROL MODULE CONNECTOR AND TERMINALS Switch the ignition to off. Disconnect the negative battery cable. 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.
4		No	Go to the next step.
5	INSPECT POWER SUPPLY CIRCUIT (+B3) FOR OPEN CIRCUIT OR SHORT TO GROUND Keyless control module connector is disconnected. Reconnect the negative battery cable. Measure the voltage at the following terminal (wiring harness-side): Keyless control module terminal 1A Is the voltage B+?	Yes	Go to the next step.
5		No	Inspect the ESCL 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 the next step.
6	VERIFY TROUBLESHOOTING COMPLETED Make sure to reconnect the disconnected connectors. Reconnect the negative battery cable. Operate the advanced key to activate the keyless control module. Clear the DTC from the keyless control module using the M-MDS. (See CLEARING DTC [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ). Operate the advanced key to activate the keyless control module. 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.
