DTC P2530:00	Ignition switch stuck off
DETECTION CONDITION	• If the IG ON time count of the instrument cluster proceeds 5 s under the following condition: ― Ignition switch signal off
FAIL-SAFE FUNCTION	Not applicable
POSSIBLE CAUSE	• Start stop unit malfunction ― Ignition switch signal output stuck off • Wiring harness malfunction ― Short or open signal in ignition switch ― Ignition switch signal terminal (start stop unit terminal 2S) malfunction • Control valve body malfunction ― Ignition switch signal terminal (start stop unit terminal 2S) pin deformity

Diagnostic procedure

STEP	INSPECTION		ACTION
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture of the PC function. • Record the freeze frame data/snap shot data.	—	Go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY STORED DTC IN START STOP UNIT • Perform the start stop unit DTC inspection using the M-MDS. (See DTC INSPECTION [START STOP UNIT].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [START STOP UNIT].)
3		No	Go to the next step.
4	INSPECT THE IGNITION CIRCUIT FOR OPEN CIRCUIT • Switch the ignition off. • Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) • Disconnect the following connectors. ― IG1 relay ― Start stop unit • Inspect for continuity between the following terminals (wiring harness-side): ― IG1 relay terminal A—Start stop unit terminal 2S • Is there continuity?	Yes	Go to the next step.
4		No	Refer to the wiring diagram and verify whether or not there is a common connector between IG1 relay terminal A and start stop unit terminal 2S. 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 6.
5	VERIFY ENGINE START • Always reconnect all disconnected connectors. • Reconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) • Does the engine start normally?	Yes	Replace the control valve body, then go to the next step. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [FW6A-EL].)
5		No	Replace the start stop unit, then go to the next step. (See START STOP UNIT REMOVAL/INSTALLATION.)
6	VERIFY DTC TROUBLESHOOTING COMPLETED • Clear the DTC using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].) • Perform the following procedure to ensure that the DTC has been resolved: 1. Switch the ignition ON (engine off or on) and wait for 10 s or more. 2. Switch the ignition off. • Perform the DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FW6A-EL].)
6		No	DTC troubleshooting completed.
