Diagnostic Procedure

STEP

INSPECTION

ACTION
1
CONFIRM IMMOBILIZER SYSTEM DTC
•  Clear the DTC from the instrument cluster and PCM using the M-MDS.
•  Perform the immobilizer system DTC inspection using the M-MDS.
•  Is the following DTC present?
―  Instrument cluster: B10D7:05
―  PCM: P1260:00
Yes
Perform the security light: 13, DTC: B10D7:05/P1260:00 inspection.
(See SECURITY LIGHT: 13, DTC: B10D7:05/P1260:00 [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)
No
Go to the next step.
2
VERIFY WHETHER THERE IS A VALID KEY
•  Are there any valid keys which can start the engine other than the cause of the displayed DTC?
Yes
Go to the next step.
No
Program an additional key referring to the immobilizer system-related parts programming, then go to the next step.
(See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [KEYLESS ENTRY SYSTEM].)
3
VERIFY WHETHER MALFUNCTION IS CAUSED BY KEY OR COIL ANTENNA
•  Switch the ignition to ON using the valid key other than the cause of the displayed DTC (engine off).
•  Clear the DTC from the instrument cluster and PCM using the M-MDS.
•  Perform the immobilizer system DTC inspection using the M-MDS.
•  Is the following DTC present?
―  Instrument cluster: B10D7:94
―  PCM: P1260:00
Yes
Replace the coil antenna, then go to the next step.
(See COIL ANTENNA REMOVAL/INSTALLATION.)
No
Dispose of the malfunctioning key and program a new key if necessary, then go to Step 6.
(See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [KEYLESS ENTRY SYSTEM].)
Note
•  To start the engine, two or more programmed keys are necessary.
4
VERIFY PCM MALFUNCTION
•  Clear the DTC from the instrument cluster and PCM using the M-MDS.
•  Perform the immobilizer system DTC inspection using the M-MDS.
•  Is the following DTC present?
―  Instrument cluster: B10D7:94
―  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.
•  Perform the immobilizer system DTC inspection using the M-MDS.
•  Is the following DTC present?
―  Instrument cluster: B10D7:94
―  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.
