Subject:
MIL ILLUMINATION WITH DTC P0101:00
APPLICABLE MODEL(S)/VINS
2011-2012 CX-7 2.3L (Turbo)
DESCRIPTION
Some vehicles may exhibit a MIL illumination with DTC P0101:00 stored in memory.
^ DTC P0101:00 - MAF sensor circuit range/performance problem
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify the customer complaint of a MIL illumination with DTC P0101:00 stored in memory.
2. Perform a Warranty Vehicle Inquiry using the eMDCS system:
- If the eMDCS Warranty Vehicle inquiry shows campaign MSP36 as "Open", reprogram the PCM according to this service bulletin and submit the claim using MSP36 Open from the Warranty Information. If the eMDCS Warranty Vehicle inquiry shows campaign MSP36 as "Closed", reprogram the PCM according to this service bulletin and submit the claim using MSP36 Closed from the Warranty Information.
3. Reboot the IDS to clear memory before reprogramming.
4. Using IDS 82.05 or 83.02 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 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 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.
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).
^ Retain a copy of the "Log Viewer" screen on IDS along with the repair order and warranty application sheet. Check the File Name after reprogramming PCM.
