STEP	INSPECTION	ACTION
1	CONFIRM MULTIPLEX COMMUNICATION SYSTEM DTC • Clear the DTC from the instrument cluster and PCM using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR 1.5, MZR 1.6].) (See AFTER REPAIR PROCEDURE [MZR 2.0, MZR 2.5].) (See AFTER REPAIR PROCEDURE [MZR 2.0 DISI i-stop].) (See AFTER REPAIR PROCEDURE [MZR 2.3 DISI Turbo].) (See AFTER REPAIR PROCEDURE [MZ-CD 1.6].) (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.0].) (See CLEARING DTC [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) • Perform the immobilizer system DTC inspection using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) • Is the following DTC present? ― Instrument cluster: U0001:88 ― PCM: U0073:00	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 (L.H.D. (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. (MZR-CD 2.2, MZR 2.0 DISI i-stop))].) (See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (R.H.D. (EXCEPT MZR-CD 2.2, MZR 2.0 DISI i-stop, MZR 1.5))].)
No	Go to the next step.
2	VERIFY WHETHER PROGRAMMING OF IMMOBILIZER SYSTEM-RELATED PARTS HAS BEEN PERFORMED AFTER REPLACE INSTRUMENT CLUSTER • After replace the instrument cluster, has the programming of immobilizer system-related parts been performed?	Yes	Go to the next step.
No	Perform the programming of immobilizer system-related parts after replace the instrument cluster only, then go to the next step. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [KEYLESS ENTRY SYSTEM].)
3	VERIFY WHETHER PROGRAMMING OF IMMOBILIZER SYSTEM-RELATED PARTS HAS BEEN PERFORMED AFTER REPLACE PCM • After replace the PCM, has the programming of immobilizer system-related parts been performed?	Yes	Go to the next step.
No	Perform the programming of immobilizer system-related parts after replace the PCM only, then go to the next step. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [KEYLESS ENTRY SYSTEM].)
4	VERIFY PCM MALFUNCTION • Clear the DTC from the instrument cluster and PCM using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR 1.5, MZR 1.6].) (See AFTER REPAIR PROCEDURE [MZR 2.0, MZR 2.5].) (See AFTER REPAIR PROCEDURE [MZR 2.0 DISI i-stop].) (See AFTER REPAIR PROCEDURE [MZR 2.3 DISI Turbo].) (See AFTER REPAIR PROCEDURE [MZ-CD 1.6].) (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.0].) (See CLEARING DTC [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) • Perform the immobilizer system DTC inspection using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) • Is the following DTC present? ― Instrument cluster: B10DA:51 ― PCM: P1260:00	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [MZR 1.5, MZR 1.6].) (See PCM REMOVAL/INSTALLATION [MZR 2.0, MZR 2.5].) (See PCM REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].) (See PCM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].) (See PCM REMOVAL/INSTALLATION [MZ-CD 1.6].) (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
No	Go to Step 6.
5	VERIFY TROUBLESHOOTING COMPLETED • Clear the DTC from the instrument cluster and PCM using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR 1.5, MZR 1.6].) (See AFTER REPAIR PROCEDURE [MZR 2.0, MZR 2.5].) (See AFTER REPAIR PROCEDURE [MZR 2.0 DISI i-stop].) (See AFTER REPAIR PROCEDURE [MZR 2.3 DISI Turbo].) (See AFTER REPAIR PROCEDURE [MZ-CD 1.6].) (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.0].) (See CLEARING DTC [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) • Perform the immobilizer system DTC inspection using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) • Is the following DTC present? ― Instrument cluster: B10DA:51 ― PCM: P1260:00	Yes	Replace the instrument cluster, then go to the next step. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
No	Go to the next step.
6	VERIFY THAT NO OTHER DTCs ARE PRESENT • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)
No	DTC troubleshooting completed.
