    DESCRIPTION

    Some vehicles may exhibit a Malfunction Indicator Lamp (MIL) illumination, with DTC P0507 stored in memory. This condition may be caused by improper idle speed control logic within Powertrain Control Module (PCM).

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

    REPAIR PROCEDURE

    1. Verify customer concern.

    2. Adjust base idle speed according to Workshop Manual (section 01-10B ENGINE TUNE-UP [FS]).

    3. Using WDS B27.4 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 WDS PTU first, then install the needed calibration file that WDS shows during PCM reprogramming. Go to "WDS Calibration" on ESI and download the "update" file. If the PTU is not updated to the latest WDS calibration level, the calibration file will not install into the PTU.

    ^ It is not necessary to remove any fuses or relays during PCM reprogramming when the WDS 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 WDS reprogramming procedure.

    ^ WDS 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 WDS software, and additional revisions made to those calibrations for service related concerns.

    ^ When reprogramming a PCM, WDS 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, if the WDS PTU is not docked and connected to 115V-120V, 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, it will damage the WDS PTU.


    4. Place an "Authorized Modification" label (P/N 9999-95-AMDC-97) with the new calibration information near the Emission Control Information Label located on the hood or in the engine compartment.

    5. Verify repair.

    NOTE :After reprogramming a PCM, it is necessary to road test the vehicle to relearn KAM (Keep Alive Memory) strategy and verify no MIL illumination or DTC's are present.
