Attachment II - Procedure





A. VEHICLE INSPECTION PROCEDURE

1. Verify that the vehicle is within the following ranges:

^ VIN Range:

1YVFP**C*45N40299 - 45N47633

1YVHP**C*45N36373 - 45N47490

- If the vehicle is within either of the above ranges, proceed to step 2.

- If the vehicle is not within either of the above ranges, return the vehicle to the customer or inventory.

2. Perform a Warranty Vehicle Inquiry using your eMDCS System and inspect vehicle for a Campaign Label RECALL 3105G attached to the vehicle's bulkhead. Refer to eMDCS System - Warranty Vehicle Inquiry Results table below.

NOTE:
Verify Recall number as the vehicle may have multiple recalls.

B. REPAIR PROCEDURE

PCM / TCM CALIBRATION LEVEL INSPECTION PROCEDURE

Using WDS version B39.3 or later software, proceed to "Module Reprogramming" and check the PCM and TCM calibration levels.

^ If WDS indicates the PCM and TCM are already at the latest calibration level (refer to "Calibration Information" table), proceed to Step 5 under "PCM/TCM PROGRAMMING" and complete an "Authorized Modifications" label. This label will inform technicians of the PCM/TCM calibration change if future repairs are necessary.

^ If WDS indicates that a later calibration is available in either PCM or TCM, proceed to "PCM/TCM PROGRAMMING" below.

PCM / TCM REPROGRAMMING

1. Reboot the WDS PTU to clear memory before reprogramming.

2. Using WDS B39.3 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 PIN 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 to keep the vehicle battery up to capacity. If you exceed 20 AMPS, it will damage the WDS PTU. Also the external battery power supply cable should be connected to the vehicle battery and the PTU.

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. Perform the TCM reprogramming procedure and reprogram the TCM to the latest available calibration (refer to the "Calibration Information" table). Verify the repair by starting the engine and making sure there are no MIL illumination or abnormal warning lights present.





5. Fill out an "Authorized Modifications" label (P/N 9999-95-AMDC-97) with the new PCM/TCM calibration information, your dealer code, and today's date (example below).





6. Place the "Authorized Modifications" label on the "A" pillar below the tear tag in the driver door jamb.

C. CAMPAIGN LABEL INSTALLATION





1. Fill out a blue "Campaign Label" (9999-95-065A-05) with Campaign No: "3105G", your dealer code, today's date (example below), and affix it to the vehicle's bulkhead as shown in "A. VEHICLE INSPECTION PROCEDURE".

2. Return vehicle to customer.
