DESCRIPTION
Some vehicles may experience surging/body vibration during light acceleration or while cruising in 4th, 5th, or 6th gear lock-up. Torque fluctuation
generated by the engine may be transmitted to the drivetrain, then amplified to the body. The Transmission Control Module (TCM) calibration has been
modified to improve driving feel.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1.
Reboot the PDS/IDS to clear memory before reprogramming.
2.
Using PDS/IDS B45.9 or later software, reprogram the TCM to the latest calibration (refer to "Calibration Information" table) by following the
"Module Reprogramming" procedure.
NOTE:
^
Always update the PDS/IDS tool first, then follow on-screen instructions to download the needed calibration file for TCM reprogramming.
^
It is not necessary to remove any fuses or relays during TCM reprogramming when the PDS/IDS screen prompts you to do so. You may
accidentally stop power to one of the TCM terminals and cause the TCM to be blanked, or you may receive error messages during the
PDS/IDS reprogramming procedure.
^
PDS/IDS shows the calibration part numbers after programming the TCM.
^
Please be aware that TCM calibration part numbers and file names listed in any Service Bulletin may change due to future releases of
PDS/IDS software, and additional revisions made to those calibrations for service related concerns.
^
When reprogramming a TCM, PDS/IDS will always display the "latest" calibration P/N available for that vehicle. If any calibration has
been revised/updated to contain new information for a new service concern/issue, it will also contain all previously released calibrations.
^
When performing this procedure, we recommend that a battery charger be installed on the vehicle battery and turned ON to a maximum
charge of no more than 20 AMPS to keep the vehicle battery up to capacity. If you exceed 20 AMPS, it could damage the VCM.
3.
After performing the TCM reprogramming procedure, verify the repair by starting the engine and making sure there are 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.
CALIBRATION INFORMATION
NOTE:
The TCM Calibration Part Numbers listed above are provided for TCM reprogramming purposes only. These are not necessarily the same Mazda
part numbers used to order an actual TCM through the Mazda Parts System. It is not necessary to order a TCM as part of this repair procedure.
