No. 3 Programming Procedure When Start Stop Unit Is Replaced Or When Start Stop Unit And Pcm Are Replaced Simultaneously

CAUTION:

• The engine cannot be started if any step or procedure is skipped. Perform all procedures in the order of the steps.
• Because it is necessary to program two or more remote transmitters to the immobilizer system-related parts to start the engine, perform the remote transmitter programming after clearing the remote transmitter.

NOTE:

• Before beginning the procedure, verify that the customer has provided all of the remote transmitters for the vehicle.
• The engine cannot be started unless two or more remote transmitters are programmed after the replacement.

Vehicle condition 

• Have two or more remote transmitters to be programmed after the replacement.

DIAGNOSTIC PROCEDURE

Step	Procedure	Action after procedure
1	REPLACE START STOP UNIT AND REPLACE START STOP UNIT/PCM SIMULTANEOUSLY Refer to START STOP UNIT REMOVAL/INSTALLATION to perform start stop unit replacement. (See START STOP UNIT REMOVAL/INSTALLATION .) Refer to PCM REMOVAL/INSTALLATION to perform PCM replacement. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5T] .)	Go to the next step.
2	PERFORM PARAMETER RESET Connect the M-MDS to the DLC-2. (See M-MDS Connecting Procedure.) Remove the remote transmitter from the vehicle (keep them 1 m or more from the vehicle) and switch the ignition ON (engine off) according to the directions on the M-MDS screen. Select the following from the M-MDS initial screen. "Body" "Special Ignition ON" Press the push button start and switch the ignition ON (engine off) according to the instructions on the M-MDS. Select the following from the M-MDS initial screen. "Body" "Security" "PATS Functions" Then, select the following from the screen menu. "Parameter Reset" Input the start stop unit and PCM in code and cancel the security access according to the directions on the M-MDS screen. NOTE: "Security access permitted" is displayed on the M-MDS screen. Perform the operation according to the directions on the M-MDS screen. NOTE: "Parameter reset completed" is displayed on the M-MDS screen. Select "Yes" according to the directions on the M-MDS. CAUTION: Because the procedure will not switch to the procedure for key ID number clearing, if "No" is selected on the M-MDS screen, select "Yes".	Go to the next step.
3	PERFORM KEY ID NUMBER CLEARING Perform the key ID number clearing and switch the ignition off according to the directions on the M-MDS screen.	Go to the next step.
4	PERFORM REMOTE TRANSMITTER 1 PROGRAMMING Switch the ignition ON (engine off). NOTE: Although the security indicator light illuminates for approx. 10 s and then turns off or flashes, continue to perform the procedure as indicated. While the push button start indicator light (green) is flashing, press the top part of the remote transmitter 1 against the center of the push button start. (See PROCEDURE FOR COMMUNICATION BETWEEN COIL ANTENNA AND REMOTE TRANSMITTER .) Verify that remote transmitter 1 programming is completed on the M-MDS screen. NOTE: When the programming is completed, the security indicator light turns off and DTC 21 is displayed after approx. 1 min. If the programming fails, the security indicator light flashes and DTC 13 is displayed after approx. 1 min.	Switch the ignition off, then go to the next step.
5	PERFORM REMOTE TRANSMITTER 2 PROGRAMMING Switch the ignition ON (engine off). While the push button start indicator light (green) is flashing, press the top part of the remote transmitter 2 against the center of the push button start. (See PROCEDURE FOR COMMUNICATION BETWEEN COIL ANTENNA AND REMOTE TRANSMITTER .) Verify that the remote transmitter 2 programming is completed on the M-MDS screen. NOTE: If the programming fails, the security indicator light flashes and DTC 13 is displayed after approx. 1 min. Are there other remote transmitters to be programmed?	Yes	If other remote transmitters are programmed, repeat Step 5.
		No	Go to the next step.
6	M-MDS COMPLETION Wait for 5 s or more after the M-MDS is completed and switch the ignition off	Go to the next step.
7	PERFORM IMMOBILIZER SYSTEM FUNCTION VERIFICATION (REMOTE TRANSMITTER 1) NOTE: Each remote transmitter is brought inside the vehicle one at a time to start the engine. Depress the brake pedal. While the push button start indicator light (green) is flashing, press the top part of the remote transmitter 1 against the center of the push button start. (See PROCEDURE FOR COMMUNICATION BETWEEN COIL ANTENNA AND REMOTE TRANSMITTER .) After the push button start indicator light (green) goes from flashing to illumination, press the push button start to start the engine.	Switch the ignition off, then go to the next step.
8	PERFORM IMMOBILIZER SYSTEM FUNCTION VERIFICATION (REMOTE TRANSMITTER 2) NOTE: Each remote transmitter is brought inside the vehicle one at a time to start the engine. Depress the brake pedal. While the push button start indicator light (green) is flashing, press the top part of the remote transmitter 2 against the center of the push button start. (See PROCEDURE FOR COMMUNICATION BETWEEN COIL ANTENNA AND REMOTE TRANSMITTER .) After the push button start indicator light (green) goes from flashing to illumination, press the push button start to start the engine.	Yes	If there are other remote transmitters to be programmed, repeat Step 7.
		No	Go to the next step.
9	VERIFY THAT REMOTE TRANSMITTER IS PROGRAMMED NOTE: Each remote transmitter is brought inside the vehicle one at a time to start the engine. Place only the programmed remote transmitter on the passenger seat and verify that the engine starts. Does engine start?	Yes	Procedure is completed.
		No	Perform the related DTC inspection to repair the malfunctioning part.
