Diagnostic Procedure

STEP

INSPECTION

ACTION

1

VERIFY DTCs

•  Clear the DTC from the instrument cluster using the M-MDS.
(See CLEARING DTC [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)

•  Verify the immobilizer system DTC using the M-MDS.
(See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)

•  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 COIL ANTENNA MALFUNCTION

•  Switch the ignition to ON using the valid key other than the cause of the displayed DTC.

•  Clear the DTC from the instrument cluster using the M-MDS.
(See CLEARING DTC [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)

•  Verify the immobilizer system DTC using the M-MDS.
(See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)

•  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 [KEYLESS ENTRY SYSTEM].)

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 INSTRUMENT CLUSTER MALFUNCTION

•  Clear the DTC from the instrument cluster using the M-MDS.
(See CLEARING DTC [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)

•  Verify the immobilizer system DTC using the M-MDS.
(See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)

•  Is the following DTC present?

―  Instrument cluster: B10D7:94

―  PCM: P1260:00

Yes

Replace the instrument cluster and program the immobilizer system-related parts.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

(See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [KEYLESS ENTRY SYSTEM].)

Go to the next step.

No

Go to Step 6.

5

VERIFY TROUBLESHOOTING COMPLETED

•  Clear the DTC from the instrument cluster using the M-MDS.
(See CLEARING DTC [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)

•  Verify the immobilizer system DTC using the M-MDS.
(See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)

•  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 1.8, MZR 2.0, MZR 2.5].)

(See PCM REMOVAL/INSTALLATION [MZR 2.0 DISI].)

(See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].)

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.
