Diagnostic Procedure

STEP

INSPECTION

ACTION
1
CONFIRM MULTIPLEX COMMUNICATION SYSTEM DTC
•  Clear the DTC from the keyless control module and PCM using the M-MDS.
•  Perform the immobilizer system DTC inspection using the M-MDS.
•  Is the following DTC present?
―  Keyless control module: 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 KEYLESS CONTROL MODULE
•  After replace the keyless control module, 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 keyless control module only, then go to the next step.
(See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START 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 [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
4
VERIFY PCM MALFUNCTION
•  Clear the DTC from the keyless control module and PCM using the M-MDS.
•  Perform the immobilizer system DTC inspection using the M-MDS.
•  Is the following DTC present?
―  Keyless control module: 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 [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 keyless control module and PCM using the M-MDS.
•  Perform the immobilizer system DTC inspection using the M-MDS.
•  Is the following DTC present?
―  Keyless control module: B10DA:51
―  PCM: P1260:00
Yes
Replace the keyless control module, then go to the next step.
(See KEYLESS CONTROL MODULE 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 (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].)
No
DTC troubleshooting completed.
