DTC P0615:12 [Advanced Keyless Entry And Push Button Start System]: MTX

DESCRIPTION	Short to power supply in starter relay circuit
DETECTION CONDITION	Starter relay input voltage is above the specification for 0.075 s when the ignition switch is off.
POSSIBLE CAUSE	Starter relay malfunction Starter cut relay connector or terminals malfunction Starter cut relay malfunction PCM connector or terminals malfunction Keyless control module connector or terminals malfunction Short to power supply in wiring harness between the following terminals: Starter relay terminal E-Keyless control module terminal 3B Starter relay terminal A-Keyless control module terminal 2F Starter relay terminal A-Starter cut relay terminal A Starter cut relay terminal D-PCM terminal 1BB (LF, L5) Starter cut relay terminal D-PCM terminal 1B (L3 WITH TC) Starter cut relay terminal D-Keyless control module terminal 3T PCM malfunction Keyless control module malfunction

DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	INSPECT RELAY Switch the ignition to off. Disconnect the negative battery cable. Remove the starter relay. Inspect the starter relay. (See RELAY INSPECTION ). Is there any malfunction?	Yes	Replace the relay, then go to Step 8.
1		No	Go to the next step.
2	INSPECT STARTER CUT RELAY CONNECTOR AND TERMINALS Disconnect the starter cut relay 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 8.
2		No	Go to the next step.
3	INSPECT STARTER CUT RELAY Inspect the starter cut relay. (See STARTER CUT RELAY INSPECTION [MTX] ). Is there any malfunction?	Yes	Replace the starter cut relay, then go to Step 8. (See STARTER CUT RELAY REMOVAL/INSTALLATION [MTX] ).
3		No	Go to the next step.
4	INSPECT PCM CONNECTOR AND TERMINALS Disconnect the PCM 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 8.
4		No	Go to the next step.
5	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 8.
5		No	Go to the next step.
6	INSPECT STARTER RELAY CIRCUIT FOR SHORT TO POWER SUPPLY Starter relay is removed. Starter cut relay, PCM and keyless control module connectors are disconnected. Inspect the wiring harness between the following terminate (wiring harness-side) for short to power supply: Starter relay terminal E-Keyless control module terminal 3B Starter relay terminal A-Keyless control module terminal 2F Starter relay terminal A-Starter cut relay terminal A Starter cut relay terminal D-PCM terminal 1BB (LF, L5) Starter cut relay terminal D-PCM terminal 1B (L3 WITH TC) Starter cut relay terminal D-Keyless control module terminal 3T Is there any malfunction?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 8.
6		No	Go to the next step.
7	INSPECT PCM Install the starter relay. Reconnect all disconnected connectors. Reconnect the negative battery cable. Measure the voltage at the following terminal (wiring harness-side): PCM terminal 1BB (LF, L5) PCM terminal 1B (L3 WITH TC) Is the voltage normal? (See PCM INSPECTION [LF, L5] ). (See PCM INSPECTION [L3 WITH TC] ).	Yes	Go to the next step.
7		No	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [LF, L5] ). (See PCM REMOVAL/INSTALLATION [L3 WITH TC] ).
8	VERIFY TROUBLESHOOTING COMPLETED Make sure to reconnect the disconnected connectors. Reconnect the negative battery cable. Switch the ignition to off using the advanced key. 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 using the advanced key. 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 ).
8		No	Go to the next step.
9	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] ).
9		No	DTC troubleshooting completed.
