LACK OF POWER DURING HARD ACCELERATION IN COLD WEATHER
|Bulletin No: 01-011/15|
|Last Issued: 06/17/2015|
- This bulletin supersedes the previous bulletin 01-011/15, issued on 06/02/15. The APPLICABLE MODEL(S)/ VINS, REPAIR PROCEDURE and CALIBRATION INFORMATION has been revised.
- Changes are noted below in Red beside the change bar.
2014-2015 Mazda3 2.0L with VINs lower than JM1BM******267077 (produced before March 30, 2015 – Japan built)
2014-2015 Mazda3 2.0L with VINs lower than 3MZBM****** 207478 (produced before April 1, 2015 – Mexico built)
2013-2016 CX-5 2.0L with VINs lower than JM3KE****** 656820 (produced before April 8, 2015)
Some vehicles may experience a lack of power during hard acceleration (approx. 6,000 rpm) in cold weather conditions below 32 °F (0 °C). DTCs P0300:00, P0301:00 and/or P0302:00 are stored in memory.
- P0300:00: Random misfire detected
- P0301:00: Cylinder No. 1 misfire detected
- P0302:00: Cylinder No. 2 misfire detected
This is caused by improper control logic of the PCM. The PCM may detect a false misfire under the subject conditions and may fall into fail safe mode. To eliminate this concern, the PCM control logic has been changed.
Customers having this concern should have their vehicle repaired using the following repair procedure.
- Verify customer concern.
- Reboot the IDS to clear memory before reprogramming.
- Using IDS 95.05 or later software, reprogram the PCM to the latest calibration (refer to “Calibration Information” table) by following the “Module Reprogramming” procedure.
- Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for PCM reprogramming.
- It is not necessary to remove any fuses or relays during PCM reprogramming when the IDS 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 IDS reprogramming procedure.
- IDS 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 IDS software, and additional revisions made to those calibrations for service related concerns.
- When reprogramming a PCM, 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.
- Start/Stop button vehicles only: DO NOT press the start/stop button during the reprogramming process.
- When performing this procedure, we recommend using the “Power Supply” mode in the Battery Management System to keep the vehicle battery up to capacity. If a different charger is used, make sure it does not exceed 20 AMPS. If it exceeds 20 AMPS, it could damage the PCM.
- After performing the PCM reprogramming procedure, clear DTCs.
- After clearing DTCs, start the engine and confirm that no warning lights stay on.
- If any DTCs should remain after performing DTC erase, diagnose the DTCs using MS3 online instructions or Workshop Manual section 01-02.
- After PCM reprogramming, it is no longer necessary to road test the vehicle to “relearn” KAM (Keep Alive Memory).

Important Information: Mazda makes no representations about the performance of third-party passthru devices. This pass-thru device list is provided voluntarily and as a courtesy. While our software meets SAE J2534, the pass-thru device manufacturer is responsible for making sure their pass-thru device operates properly on each Mazda vehicle and with Mazda software. We have listed the devices below because their manufacturers have attested that the tools have been validated to work. From time to time, we may test these devices. If we determine they do not operate properly or are obsolete, we may remove them from the list, without notice. Additionally, pass-thru devices listed here have been listed for their use with Mazda North American products only. While they may work with some European and other vehicles, they may not meet the requirements for those regions or operate properly.

**Many J2534 manufacturers sell and market similar J2534 devices with like names. Please exercise caution when using the list above for purposes of understanding devices Mazda has validated for use. J2534 Pass-thru Device Suppliers: Mazda has validated the J2534 devices listed on this page. Mazda does not plan to validate additional J2534 devices at this time.
PCM Reprogramming Process Overview
- Purchase a subscription to PCM Reprogramming on this website.
- Download the application and install it on your PC.
- Connect the J2534 pass-thru device to the PC and the vehicle, and power it up.
- Run the application installed on your PC.
- The application will determine whether or not a new calibration file is available.
- If you choose to use the new file, the module will be reprogrammed.
- If PATS functionality is required, it can be chosen from the toolbox.
