Diagnostic Procedure

Step	Inspection		Action
1	INSPECT STARTER INTERLOCK SWITCH CONNECTOR AND TERMINALS • Switch the ignition to off. • Disconnect the negative battery cable. • Disconnect the starter interlock switch connector. • Inspect the connector and terminals (corrosion, damage, pin disconnection). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 12.
1		No	Go to the next step.
2	INSPECT STARTER INTERLOCK SWITCH • Inspect the starter interlock switch. (See STARTER INTERLOCK SWITCH INSPECTION [LF, L5].) (See STARTER INTERLOCK SWITCH INSPECTION [ZY, Z6].) (See STARTER INTERLOCK SWITCH INSPECTION [MZ-CD 1.6 (Y6)].) (See STARTER INTERLOCK SWITCH INSPECTION [MZR-CD 2.2].) (See STARTER INTERLOCK SWITCH INSPECTION [MZR 2.0 DISI i-stop].) • Is there any malfunction?	Yes	Replace the starter interlock switch, then go to Step 12.
2		No	Go to the next step.
3	INSPECT KEYLESS CONTROL MODULE CONNECTOR AND TERMINALS • Disconnect the keyless control module connector. • Inspect the connector and terminals (corrosion, damage, pin disconnection). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 12.
3		No	Go to the next step.
4	INSPECT STARTER INTERLOCK SWITCH CIRCUIT FOR SHORT TO GROUND • Starter interlock switch and keyless control module connectors are disconnected. • Inspect for continuity between the following terminal (wiring harness-side) and body ground: ― Starter interlock switch terminal A • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, then go to Step 12.
4		No	Go to the next step.
5	INSPECT CPP SWITCH CONNECTOR AND TERMINALS • Disconnect the CPP switch connector. • Inspect the connector and terminals (corrosion, damage, pin disconnection). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 12.
5		No	Go to the next step.
6	INSPECT CPP SWITCH • Inspect the CPP switch. (See CLUTCH PEDAL POSITION (CPP) SWITCH INSPECTION [LF, L5].) (See CLUTCH PEDAL POSITION (CPP) SWITCH INSPECTION [ZY, Z6].) (See CLUTCH PEDAL POSITION (CPP) SWITCH INSPECTION [MZ-CD 1.6 (Y6) (EURO4 emission level)].) (See CLUTCH PEDAL POSITION (CPP) SWITCH INSPECTION [MZ-CD 1.6 (Y6) (EURO5 emission level)].) (See CLUTCH PEDAL POSITION (CPP) SWITCH INSPECTION [MZR-CD 2.2].) (See CLUTCH PEDAL POSITION (CPP) SWITCH INSPECTION [MZR 2.0 DISI i-stop].) • Is there any malfunction?	Yes	Replace the CPP switch, then go to Step 12. (See CLUTCH PEDAL REMOVAL/INSTALLATION.)
6		No	Go to the next step.
7	INSPECT CPP SWITCH CIRCUIT FOR OPEN CIRCUIT • Starter interlock switch, CPP switch and keyless control module connectors are disconnected. • Inspect for continuity between the following terminals (wiring harness-side): ― CPP switch terminal A—Keyless control module terminal 4V ― CPP switch terminal B—Body ground • Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 12.
8	INSPECT STARTER CUT RELAY CONNECTOR AND TERMINALS • Disconnect the starter cut relay connector. • Inspect the connector and terminals (corrosion, damage, pin disconnection). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 12.
8		No	Go to the next step.
9	INSPECT STARTER CUT RELAY • Inspect the starter cut relay. (See STARTER CUT RELAY INSPECTION [MTX].) • Is there any malfunction?	Yes	Replace the starter cut relay, then go to Step 12. (See STARTER CUT RELAY REMOVAL/INSTALLATION [MTX].)
9		No	Go to the next step.
10	INSPECT STARTER CUT RELAY CIRCUIT FOR SHORT TO GROUND OR OPEN CIRCUIT • Starter interlock switch, CPP switch, starter cut relay and keyless control module connectors are disconnected. • Switch the ignition to ON. • Measure the voltage at the following terminal (wiring harness-side): ― Starter cut relay terminal A • Is there any voltage?	Yes	Go to the next step.
10		No	Repair or replace the wiring harness for a possible short to ground or open circuit, then go to Step 12.
11	INSPECT STARTER CUT RELAY CIRCUIT FOR SHORT TO POWER SUPPLY • Starter interlock switch, CPP switch, starter cut relay and keyless control module connectors are disconnected. • Measure the voltage at the following terminal (wiring harness-side): ― Starter cut relay terminal D • Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to the next step.
11		No	Go to the next step.
12	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].) • Switch the ignition to off using the advanced key. • Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS. (See DTC INSPECTION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) • Is the same DTC present?	Yes	Replace the keyless control module, then go to the next step. (See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION.)
12		No	Go to the next step.
13	VERIFY THAT NO OTHER DTCs ARE PRESENT • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
13		No	DTC troubleshooting completed.
