DTC P0615:11 (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM) DIAGNOSTIC PROCEDURE - MTX

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 GROUND Starter relay is removed. Starter cut relay, PCM and keyless control module connectors are disconnected. Inspect for continuity between the following terminals (wiring harness-side) and body ground: Keyless control module terminal 3B Keyless control module terminal 2F Starter cut relay terminal A PCM terminal 1BB (LF, L5) PCM terminal 1B (L3 WITH TC) Keyless control module terminal 3T Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground. Inspect the ST SIG 10 A fuse. Replace the fuse, if necessary. Go to Step 8.
6		No	Go to the next step.
7	INSPECT PCM Install the starter relay. Reconnect the starter cut relay, PCM, and keyless control module 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. 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] .) Crank the engine. 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.
