Diagnostic Procedure

Step	Inspection		Action
1	VERIFY RELATED STORED DTC • 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 DTC U0001:88 or U0101:00 also present?	Yes	Go to the applicable DTC inspection. (See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (L.H.D. (EXCEPT MZR-CD 2.2, MZR 2.0 DISI i-stop))].) (See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (R.H.D. (MZR 1.5))].) (See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (R.H.D. (EXCEPT MZR-CD 2.2, MZR 2.0 DISI i-stop, MZR 1.5))].)
1		No	Go to the next step.
2	INSPECT SELECTOR LEVER COMPONENT CONNECTOR • Switch the ignition to off. • Disconnect the negative battery cable. • Disconnect the selector lever component 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 8.
2		No	Go to the next step.
3	INSPECT KEYLESS CONTROL MODULE CONNECTOR • 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 8.
3		No	Go to the next step.
4	INSPECT SELECTOR LEVER COMPONENT CIRCUIT FOR SHORT TO GROUND • Selector lever component and keyless control module connectors are disconnected. • Inspect for continuity between the following terminal (wiring harness-side) and body ground: ― Selector lever component terminal G • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, then go to Step 8.
4		No	Go to the next step.
5	INSPECT SELECTOR LEVER COMPONENT CIRCUIT FOR SHORT TO POWER SUPPLY • Selector lever component and keyless control module connectors are disconnected. • Reconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZR 1.5, MZR 1.6].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.0, MZR 2.5].) (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.0].) • Switch the ignition to ON. • Measure the voltage at the following terminal (wiring harness-side): ― Selector lever component terminal G • Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 8.
5		No	Go to the next step.
6	INSPECT SELECTOR LEVER COMPONENT • Inspect the selector lever component. (See SELECTOR LEVER INSPECTION.) • Is there any malfunction?	Yes	Replace the selector lever component, then go to Step 8. (See AUTOMATIC TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION.)
6		No	Go to the next step.
7	INSPECT SELECTOR LEVER COMPONENT CIRCUIT FOR OPEN CIRCUIT • Selector lever component and keyless control module connectors are disconnected. • Switch the ignition to off. • Disconnect the negative battery cable. • Inspect for continuity between the following terminals (wiring harness-side): ― Selector lever component terminal G—Keyless control module terminal 3S • 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 the next step.
8	VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect the disconnected connectors. • Reconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZR 1.5, MZR 1.6].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.0, MZR 2.5].) (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.0].) • 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, then to ON. • 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 DTC P081C:62 present?	Yes	Replace the keyless control module, then go to the next step. (See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION.)
8		No	Go to the next step.
9	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].)
9		No	DTC troubleshooting completed.
