PUSH BUTTON START SYSTEM DOES NOT OPERATE [SECURITY AND LOCKS]

id0903k7012600

Description	When the push button start is pressed, the ignition cannot be switched to ACC or ON (engine off).
Possible Causes	•  Fuse malfunction •  Customer mis-operation or misunderstanding •  Open circuit in wiring harness between the following terminals: ―  Start stop unit terminal 1H and push button start terminal C ―  Start stop unit terminal 2J and push button start terminal I ―  Start stop unit terminal 1AF and ground ―  Start stop unit terminal 2B and ground ―  Start stop unit terminal 2A and ground

Diagnostic Procedure

Step	Inspection		Action
1	VERIFY REMOTE TRANSMITTER CONDITION •  Verify that a metal object is not installed to the remote transmitter. •  Is a metal object installed?	Yes	Remove the metal object from the remote transmitter, then go to the next step.
		No	Go to the next step.
2	VERIFY MALFUNCTION CAUSE •  Ask the customer malfunction condition. •  Did the customer operate the push button start with all the push button start system operation conditions met?	Yes	Go to the next step.
		No	System is normal. (Explain the customer operation condition.)
3	VERIFY ROOM 25 A FUSE AND INTERIOR 15 FUSE CONDITIONS •  Visually inspect the ROOM 25 A fuse and INTERIOR 15 A fuse for disconnection. •  Is there any fuse disconnection?	Yes	Install the ROOM 25 A fuse and INTERIOR 15 A fuse, then go to Step 7.
		No	Go to the next step.
4	VERIFY STEERING LOCK CONDITION •  Verify that the steering lock operates normally. •  Does the steering lock operate normally?	Yes	Go to the next step.
		No	Refer to "steering lock function does not operate" malfunction diagnosis and perform the inspection. (See STEERING LOCK FUNCTION DOES NOT OPERATE [SECURITY AND LOCKS].)
5	INSPECT IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN START STOP UNIT AND PUSH BUTTON START •  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.) •  Disconnect the Start stop unit and push button start connector. •  Inspect for continuity between the following terminals (vehicle wiring harness). ―  Start stop unit terminal 1H and push button start terminal C ―  Start stop unit terminal 2J and push button start terminal I •  Is there continuity?	Yes	Go to the next step.
		No	•  Repair or replace the wiring harness for an open circuit. •  After repair procedure, go to Step 7.
6	INSPECT IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN START STOP UNIT AND GROUND •  Verify that the start stop unit connector is disconnected. •  Inspect for continuity between the following terminals (vehicle wiring harness). ―  Start stop unit terminal 1AF and ground ―  Start stop unit terminal 2B and ground ―  Start stop unit terminal 2A and ground •  Is there continuity?	Yes	Go to the next step.
		No	•  Repair or replace the wiring harness for an open circuit. •  After repair, go to the next step.
7	VERIFY IF MALFUNCTION CAUSE WAS CORRECTED •  Does the push button start button operate correctly?	Yes	Troubleshooting completed. (Explain the contents of the servicing to the customer.)
		No	If the malfunction has not been resolved, repeat the inspection from Step 1.
