3719F REPAIR PROCEDURE

REPAIR PROCEDURE:  PCM REPROGRAMMING by MMDS (IDS)

 

NOTE:

  • Follow the below “Service Caution for reprogramming”.

 

  1. Reprogram the PCM with the Mazda Modular Diagnostic System (M-MDS) using IDS 113.06 software. At this time, please do not use any later version of the software.

 

NOTE:

  • Verify the current PCM file name in the vehicle by log view screen. If it is the same as that in the below chart or later one, you do not need to reprogram it.
  • Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for PCM reprogramming.
  • Follow the attached “Service Caution for reprogramming”.

 

  1. Verify the repair by starting the engine and making sure there is no MIL illumination or abnormal warning lights present.

NOTE:

  • If any DTCs should remain after performing DTC erase, diagnose the DTCs according to the appropriate Troubleshooting section of the Workshop Manual.

 

  1. After the reprogramming, verify the calibration file name with the chart below at Log Viewer screen of the (PCM) FILENAME.

 

Calibration files information  

NOTE:

  • If the calibration file is with the suffix in the table or later, the TCM already has the modified calibration.
  • Older file name column shows the first four letters of the older file name only if some of the older file names are different from the new file name.

WARRANTY INFORMATION
Recall Campaign 3719F

 

CONDITION OF CONCERN

On certain subject vehicles, the powertrain control module (PCM) software controlling the hydraulic valve clearance adjuster may operate improperly. This occurs when transitioning from cylinder deactivation to full cylinder activation modes, due to inappropriate control logic of the PCM.   As a result, an intake valve rocker arm may come out of position and make contact with internal engine parts, which may cause an engine misfire, and/or Malfunction Indicator Light (MIL) illumination.  Loss of engine power or engine stall without ability to be restarted can occur while driving, which may increase the risk of a crash.

 

OUTLINE OF REPAIR

Reprogram the PCM with improved software, using M-MDS. The repair must be performed on all subject vehicles. Please refer to the Repair Procedure document on MGSS for further details.

Response regarding question in Recall Acknowledgement Letter:

 

<< Regarding the added request >>

Please confirm that there could not be a situation where the incorrect software results in minimal engine damage from rocker arm contact, yet the damage may not be evident until sometime later.

 

(Answer)

There is no situation where the failure could go undetected and cause damage sometime after the recall remedy is completed.

The rocker arm comes out of position only when a switch between cylinder deactivation/activation occurs, and the software program to increase oil pressure to hydraulic valve adjusters is incorrect. If the rocker arm starts to come out of position during this switch, there is a threshold for full separation and partial separation.

  • In partial separation condition, the rocker arm maintains close alignment to intended operating position, and will return to normal position quickly with no effect on engine performance.
  • In full separation condition, the rocker arm alignment passes the partial separation threshold and will move fully out of position, causing damage to the engine.

Since the remedy software corrects the oil pressure control program of the hydraulic valve clearance adjuster, if a customer did not already experience engine damage or engine failure due to the defect, they will not have related issues after they have the remedy completed.
