Body and Accessories).

Some technicians may experience an unsuccessful body control module (BCM) reprogramming event, when choosing the Reprogram ECU

selection on the Service Programming System (SPS).

The technician may also notice that when attempting to reprogram the BCM again after this incident has occurred, the BCM may not complete the

programming event.

This condition may be caused by the following:

- A reprogramming event that was interrupted due to a lack of communication between the vehicle and the TIS2WEB terminal.

- The vehicle experienced low system voltage during the reprogramming event.

Important

Do not replace the BCM for this condition.

SPS Programming Process Selection

Perform this procedure first.

1. If reprogramming has failed during the initial reprogramming event, back out of the SPS application completely.

2. Re-select SPS from the TIS2WEB terminal application.

3. When selecting the Programming Process , choose Replace and Program ECU , even though a new BCM is NOT being installed.

4. Reprogram the BCM using the Service Programming System (SPS) with the latest calibration available on TIS2WEB. Refer to the SPS

procedures in SI.

When using a multiple diagnostic interface (MDI) for reprogramming, ensure that it is updated with the latest software version.

When using a Tech 2(R) for reprogramming, ensure that it is updated with the latest software version.

During programming, the battery voltage must be maintained within the proper range of 12-15 volts. Only use the approved Midtronics(R) PSC 550

Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.

BCM Still Fails to Reprogram

If the BCM still fails to reprogram perform this procedure:

1. Turn OFF the ignition, and remove the key.

2. Remove the fuses that power up the following modules/components for a minimum of 2 minutes:

- BCM

- EBCM

- ECM

- IS LPS (located in the left IP fusebox)

- TCM

3. Open and close the driver door. Allow enough time for the retained accessory power (RAP) to turn OFF.

4. Reinstall the fuses.

5. When selecting the Programming Process , choose Replace and Program ECU , even though a new BCM is NOT being installed.

6. Reprogram the BCM using the Service Programming System (SPS) with the latest calibration available on TIS2WEB. Refer to the SPS

procedures in SI.

When using a multiple diagnostic interface (MDI) for reprogramming, ensure that it is updated with the latest software version.

When using a Tech 2(R) for reprogramming, ensure that it is updated with the latest software version.

During programming, the battery voltage must be maintained within the proper range of 12-15 Volts. Only use the approved Midtronics(R) PSC

550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.
