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 (produced before Aug. 8, 2006)

DESCRIPTION

A MIL illumination with DTC P0012 / VVT Retarded is stored in PCM memory.

Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE

1. Reboot the PDS/IDS to clear memory before reprogramming.

2. Using PDS/IDS B45 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 PDS/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 PDS/

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 PDS/IDS 

reprogramming procedure.

• PDS/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 PDS/IDS software, and additional revisions made to those 

calibrations for service 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 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.

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 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).

4. 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. 

5. Place the “Authorized Modifications” label on the “A” pillar below the tear tag in the driver door jamb. The 

“Authorized Modification” label will inform technicians of the PCM calibration change if future repairs are 

necessary.
