Diagnostic Procedure

SECURITY INDICATOR LIGHT: 13, DTC: B13D3:94/P1260:00 [START STOP UNIT] DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY DTCs WITH REMOTE TRANSMITTER IN DIFFERENT LOCATIONS Perform the following procedure 3 times with the remote transmitter inside the cabin with certainty. Switch the ignition off. Switch the ignition ON (engine off or on). Retrieve the immobilizer system DTCs using the M-MDS. (See DTC INSPECTION [START STOP UNIT] .) Move the remote transmitter to a different location. Is the security indicator light: 13, the same Pending DTC present?	Yes	Go to the next step.
1		No	Go to Step 10.
2	PERFORM DTC INSPECTION AND VERIFY KEYLESS RECEIVER MALFUNCTION Clear the DTC for the start stop unit using the M-MDS. (See CLEARING DTC [START STOP UNIT] .) Retrieve the start stop unit DTCs using the M-MDS. (See DTC INSPECTION [START STOP UNIT] .) Is DTC U201F:11/U201F:12 displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [START STOP UNIT] .)
2		No	Go to the next step.
3	INSPECT PUSH BUTTON START CONNECTOR Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Disconnect the push button start connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
3		No	Repair or replace the connector, then go to Step 9.
4	INSPECT KEYLESS RECEIVER CONNECTOR CONDITION Disconnect the keyless receiver connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
4		No	Repair or replace the connector, then go to Step 9.
5	INSPECT START STOP UNIT CONNECTOR Disconnect the start stop unit connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
5		No	Repair or replace the connector, then go to Step 9.
6	INSPECT KEYLESS RECEIVER CIRCUIT FOR OPEN CIRCUIT Verify that the start stop unit and keyless receiver connectors are disconnected. Inspect for continuity between the following terminals (wiring harness-side): Start stop unit terminal 2Q-Keyless receiver terminal A Start stop unit terminal 2R-Keyless receiver terminal B Is there continuity?	Yes	Go to the next step.
6		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: Start stop unit terminal 2Q-Keyless receiver terminal A Start stop unit terminal 2R-Keyless receiver terminal B If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 9.
7	INSPECT REMOTE TRANSMITTER BATTERY POWER Always reconnect all disconnected connectors. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Inspect the battery power of the remote transmitter. (See REMOTE TRANSMITTER BATTERY VOLTAGE INSPECTION .) Is the warning indication displayed on the multi-information display? (with multi-information display) Does the KEY indicator light (green) flash? (without multi-information display)	Yes	NOTE: If a warning display is indicated in the multi-information display, the battery power of the remote transmitter is low. Replace the remote transmitter battery and go to Step 9. (See REMOTE TRANSMITTER DISASSEMBLY/ASSEMBLY .)
7		No	Go to the next step.
8	VERIFY IF MALFUNCTION CAUSE IS REMOTE TRANSMITTER Always reconnect all disconnected connectors. Reconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Clear the DTC for the immobilizer system using the M-MDS. (See CLEARING DTC [START STOP UNIT] .) Re-program key ID number of the remote transmitter. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING .) Retrieve the immobilizer system DTCs using the M-MDS. (See DTC INSPECTION [START STOP UNIT] .) Is the security indicator light: 13, the same Pending DTC present?	Yes	Replace the remote transmitter, then go to the next step. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING .)
8		No	Go to Step 10.
9	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Always reconnect all disconnected connectors. Reconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Clear the DTC for the immobilizer system using the M-MDS. (See CLEARING DTC [START STOP UNIT] .) Retrieve the immobilizer system DTCs using the M-MDS. (See DTC INSPECTION [START STOP UNIT] .) Is the security indicator light: 13, the same Pending DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the start stop unit. (See START STOP UNIT REMOVAL/INSTALLATION .) Go to the next step.
9		No	Go to the next step.
10	VERIFY IF OTHER DTCs DISPLAYED Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [START STOP UNIT] .)
10		No	DTC troubleshooting completed.
