REPROGRAMMING OF BATTERY CONTROL MODULE (BCM)

SERVICE INFORMATION

As of STAR Diagnosis (DAS) version 02/05, the BCM can be reprogrammed via the vehicle diagnostic socket X11/4. This document describes specific requirements for reprogramming depending on which version of STAR Diagnosis you are using.

NOTE: Prior to reprogramming, ensure sufficient vehicle voltage supply (>12.5 V) using battery charger. Do not attach the negative terminal of the battery charger to the vehicle battery, but rather to a vehicle ground point as per WIS document AR54.10-P-1130T.

STAR DIAGNOSIS VERSION 02/05

When working with DAS version 02/05, selecting the battery control module with the part numbers listed below, automatically elicits a prompt to reprogram the unit to part number A211 540 69 45 with a software release of 18/03. The affected part numbers are:

A211 540 13 45
A211 540 27 45
A211 540 42 45

STAR DIAGNOSIS VERSION 03/05

Starting with DAS version 03/05, a selection window will appear where you can choose whether to reprogram the BCM immediately or at later time.

To reprogram, navigate to the following STAR Diagnosis menu: Control Units -> Body -> BCM- Battery Control Module

NOTE: Following this selection, DAS performs a background query for the control unit part number and displays a prompt for reprogramming if the part number matches the previously three listed numbers. To perform the reprogramming, carefully follow the steps described in DAS.

CAUTION: Aborting the reprogramming procedure will make the BCM inoperable and require that the BCM be replaced.

NOTE: If mandatory used part return is in effect (test/remaining market), a notice stating "BCM defective due to flash abort" must be cited on the warranty return delivery document.

NOTE: Following reprogramming, the new part number A211 540 69 45 with software release 18/03 is permanently entered into the BCM. During all subsequent work with DAS, the new part number will be shown, although a BCM with a preceding part number on the printed label may be installed.

NOTE: The following allowable labor operations should be used when submitting a warranty claim for this repair.

IN CASE OF WARRANTY
