2		No	Go to the next step.
3	INSPECT KEYLESS RECEIVER POWER SUPPLY CIRCUIT FOR SHORT TO GROUND Keyless receiver and keyless control module connectors are disconnected. Inspect for continuity between the following terminal (wiring harness-side) and body ground: Keyless receiver terminal A 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	INSPECT KEYLESS RECEIVER Reconnect the keyless receiver and the keyless control module connectors. Inspect the keyless receiver. (See KEYLESS RECEIVER INSPECTION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ). Is there any malfunction?	Yes	Replace the keyless receiver, then go to the next step. (See KEYLESS RECEIVER REMOVAL/INSTALLATION ).
4		No	Go to the next step.
5	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] ).
