# 2007 CX-7 - MIL ILLUMINATION WITH DTC P0012 / VVT RETARDED 

# BULLETIN NOTE This bulletin supersedes the previous bulletin issued on 11/01/06. The APPLICABLE MODEL(S)/VINS and DESCRIPTION have been revised. 

# APPLICABLE MODEL(S)/VINS 2007 CX-7 vehicles with VINs lower than JM3ER****70130639 (prod uced before Aug. 8, 2006) 

# DESCRIPTION A MIL illumination with DTC P0012 / VVT Retarded is stored in PCM memory. Customers having this concern shou ld have their vehicle repaired using the fo llowing repair procedure. 

# REPAIR PROCEDURE 1. Reboot the PDS/IDS to clear memory beforereprogramming. 2. Using PDS/IDS B45 or later software, repro gram the PCM to the la test calibration (refer to“Calibration Information” table) by follo wing the “Module Reprogramming” procedure. NOTE: • Always update the PDS/IDS tool first, then follow on -screen instructions to downlo ad the needed calibration file for PCM reprogramming. • It is not necessary to remove any fuses or relays during PCM reprogramming whe n the PDS/ IDS screen prompts you to do so. You ma y accidentally stop power to one of the PCM terminals and cause the PCM 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 PCM. • Please be aware that PCM calib ration part numbers and file na mes listed in an y Service Bulletin may change due to future rele ases of PDS/IDS software, and additio nal revisions made to those calibrations for serv ice related concerns. • When reprogramming a PCM, 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 batt ery 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.

Fill out an “Authorized Modifications” label (P/N 9999-95-AMDC-97) with the new PCM calibration information, your dealer code , and today’s date.
