Attachment III - Technical Information

OVERVIEW

As part of a class action settlement, technicians are to use the IDS to inspect the PCM part number and recalibrate the PCM if required.

INSPECTION

To identify the PCM part number, perform the follow steps:

1. Verify that the IDS is updated to software release B40.2 or later.

2. Connect the IDS to the vehicle and start a session.

A. Place the key to the ON position.

B. Select Start New Session.

C. From Start New Session, select All Other.

D. Follow the screen prompts.

E. The IDS will establish communication with the vehicle and select the correct vehicle.

F. Confirm the vehicle.

3. On the lower LH portion of the IDS screen, select the Log Viewer tab and touch the tick.





4. Locate the PCM part number, record the number on the repair order and compare to the chart.

5. If the PCM part number is listed on the PCM Part Number chart, proceed to the Service Procedure. If the PCM part number is not listed on the PCM Part Number chart, no further action is required.

SERVICE PROCEDURE

NOTE:
Loss of or inadequate battery voltage during the recalibration process will cause a recalibration failure and require the PCM to be restored using an IDS and repeating this procedure.

1. Make sure that the batteries are fully charged (at least 12 volts) and all accessories (radio, interior fan, headlights, etc.) are switched off. It is strongly recommended that the vehicle be connected to a battery charger during the recalibration process to avoid potential low-voltage issues.

2. With the IDS still connected, return to the main menu by selecting the vehicle identification tab at the lower left of the screen.

3. Select the Tool Box tab.

4. Select Module Programming and touch the tick.

5. Select Module Programming again and then select PCM. Touch the tick.

6. A screen will appear stating a later PCM calibration is available. Follow the on-screen instructions to install the latest PCM calibration.
