B10DA:62

PCM

P1260:00

DETECTION CONDITION

• Communication error between keyless control module and PCM (data mis-match).

POSSIBLE CAUSE

• Immobilizer system-related parts have not been programmed after replacing the PCM.

• PCM malfunction

• Keyless control module malfunction

STEP	INSPECTION	ACTION
1	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].)
2	VERIFY PCM MALFUNCTION • Clear the DTC from the keyless control module and PCM using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) (See AFTER REPAIR PROCEDURE [LF, L5].) (See AFTER REPAIR PROCEDURE [ZY, Z6].) (See AFTER REPAIR PROCEDURE [MZ-CD 1.6 (Y6) (EURO4 emission level)].) (See AFTER REPAIR PROCEDURE [MZ-CD 1.6 (Y6) (EURO5 emission level)].) (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) (See AFTER REPAIR PROCEDURE [MZR 2.0 DISI i-stop].) • Perform the immobilizer system DTC inspection using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [LF, L5].) (See PCM REMOVAL/INSTALLATION [ZY, Z6].) (See PCM REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6) (EURO4 emission level)].) (See PCM REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6) (EURO5 emission level)].) (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].) (See PCM REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)
No	Go to Step 4.
3	VERIFY TROUBLESHOOTING COMPLETED • Clear the DTC from the keyless control module and PCM using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) (See AFTER REPAIR PROCEDURE [LF, L5].) (See AFTER REPAIR PROCEDURE [ZY, Z6].) (See AFTER REPAIR PROCEDURE [MZ-CD 1.6 (Y6) (EURO4 emission level)].) (See AFTER REPAIR PROCEDURE [MZ-CD 1.6 (Y6) (EURO5 emission level)].) (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) (See AFTER REPAIR PROCEDURE [MZR 2.0 DISI i-stop].) • Perform the immobilizer system DTC inspection using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)].) • Is the same DTC present?	Yes	Replace the keyless control module, then go to the next step. (See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION.)
No	Go to the next step.
4	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.

STEP

INSPECTION

ACTION

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.

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].)

VERIFY PCM MALFUNCTION

• Clear the DTC from the keyless control module and PCM using the M-MDS.
