2010 Mazda 3 L4-2.5LFACTORY OEM SERVICE PROCEDURE
Engine Controls - MIL ON/DTC P0507 Set
Bulletin No: 01-042/10
Last Issued: 07/27/2010
Subject:
MIL ON WITH DTC P0507
APPLICABLE MODEL(S)/VINS
2010 Mazda3 vehicles (with M/T) with VINS lower than JM1BL******354797 (produced before July 1, 2010)
DESCRIPTION
Some vehicles may experience the MIL ON with DTC P0507 when half-clutch engagement is kept for more than a minute. This long half-clutch engagement may lead to a false detection of idle condition by the PCM. To correct the problem, the control logic of PCM will be changed.
P0507: Idle air control system RPM higher than expected
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Perform troubleshooting for DTC P0507 without replacing the PCM.
^ If the problem is corrected, go to step 6.
^ If still unable to correct the problem go to to step 3.
3. Reboot the IDS to clear memory before reprogramming.
4. Using IDS 66.13A 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 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.
^ 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.
5. 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. Also be sure to keep the copy of Log Viewer" screen on M-MDS along with a repair order and warranty application sheet, until the vehicle's warranty period expires.
NOTE:
^ If any DTCs should remain after 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).
6. Verify repair.
