01-005/05 2003 & 2003.5 MAZDASPEED PROTEGE - HESITATION AND/OR INTERMITTENT STUMBLE UNDER ACCELERATION
Note: This bulletin supersedes the following TSB(s): 01-022/03. Please update your records accordingly.
BULLETIN NOTE This bulletin supersedes the previous bulletin 01-022/03, issued on 10/06/03. The REPAIR PROCEDURE, CALIBRATION and WARRANTY INFORMATION have been revised.
APPLICABLE MODEL(S)/VINS
2003 and 2003.5 MAZDASPEED Protege
DESCRIPTION
A new calibration has been introduced to correct hesitation and/or intermittent stumble under acceleration. To correct this concern, reprogram the PCM of all MAZDASPEED Proteges using the following repair procedure.
NOTE: It is also recommended that the PCM reprogramming procedure be performed on all dealer stock of 2003 and 2003.5 MAZDASPEED Proteges prior to sale.
REPAIR PROCEDURE
1. Reboot the WDS PTU to clear memory before reprogramming.
2. Using WDS B27.4 or later software, reprogram the PCM to the latest calibration (refer to "Calibration Information" table) by following the "Module Reprogramming" procedure.
NOTE: ^ Always update the WDS PTU first, then install the needed calibration file that WDS shows during PCM reprogramming. Go to "WDS Calibration" on ESI and download the "update" file. If the PTU is not updated to the latest WDS calibration level, the calibration file will not install into the PTU.
^ It is not necessary to remove any fuses or relays during PCM reprogramming when the WDS screen prompts you to do so. You may accidentally stop power to one of the PCM terminals and cause the PCM to be blanked, or you may receive error messages during the WDS reprogramming procedure.
^ WDS shows the calibration part numbers after programming the PCM.
^ Please be aware that PCM calibration part numbers and file names listed in any Service Bulletin may change due to future releases of WDS software, and additional revisions made to those calibrations for service related concerns.
^ When reprogramming a PCM, WDS 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, if the WDS PTU is not docked and connected to 115V - 120V, 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 will damage the WDS PTU.
3. After performing the PCM 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 afier performing DTC erase, diagnose the DTCs according to the appropriate Troubleshooting section of the Workshop Manual.
^ After PCM reprogramming, it is no longer necessary to road test the vehicle to "relearn" KAM (Keep Alive Memory).
4. Place an "Authorized Modification" label (P/N 9999-95-AMDC-97) with the new calibration information near the Emission Control Information Label located on the hood or in the engine compartment.
CALIBRATION INFORMATION
NOTE: The PCM Calibration Part Numbers listed above are provided for PCM reprogramming purposes only. These are not necessarily the same Mazda part numbers used to order an actual PCM through the Mazda Parts System. It is not necessary to order a PCM as part of this repair procedure.
WARRANTY INFORMATION
NOTE: ^ This warranty information applies only to verified customer complaints on vehicles eligible for warranty repair. Refer to the SRT microfiche for warranty term information.
^ Additional diagnostic time cannot be claimed for this repair.
