SUBJECT
General Module Replacement

MODEL
E38 (7 Series), E39 (5 Series)

SITUATION

In order to determine the reason for failures and to correct these failures, all General Modules returned to the WPRC are tested by the supplier. On a large proportion of General Modules, no fault can be found.

-- Modules were replaced on vehicles which fall within the range of Service Action # 248 (SIB 61 15 98 - Service Action to Recode General Module) and which have a customer complaint of "dead battery". Examination of the modules shows that they have not been recoded.

-- Modules were also replaced on vehicles manufactured prior to the above Service Action for a customer complaint of "dead battery" although the General Modules on these vehicles are not affected by the fault pattern described in the Service Action.

-- Many modules that were returned, had no customer complaint, and the "Diagnostic Report/Test Code", which is an important source of information, is not provided.

To improve the information provided for failure analysis, and reduce the number of unnecessary General Module replacements, the procedure described below must be followed.

PROCEDURE

On vehicles that are affected by the Service Action # 248 (vehicles produced 8/98 to 11/98), the General Module must be recoded if the customer complaint is for "dead battery".

Before replacing a General Module, diagnosis must be carried out using either DIS, or MODiC. For a customer complaint of "dead battery", refer to SIB 61 08 00

(Closed Circuit Current Measurement).

Before replacing the General Module, the Test Code must be stored and the Diagnostic Report printed out as follows:

1. Using DIS, or MoDiC, select "Diagnosis"

2. Select any ZKE subsystem (for example, "Locking and Security Functions"/"Central Locking-system (ZKE)")

3. Select "Test schedule"

4. Select "Service Functions" / "1 Test code"

5. Store the Test Code by pressing the "R Store test code" button.

6. After completing the diagnosis, print out the "Diagnosis Report". The stored Test Code will be printed out on the "Diagnosis Report".

WARRANTY INFORMATION

Copies of the "Diagnosis Report" must be attached to the part removed, and to the Repair Order.

The "Diagnosis Report" must then accompany the General Module when it is sent to the WPRC.

The Repair Order must always record the following relating to any General Module replacement:

-- The Customer Complaint

-- The Cause

-- The Correction

Parts replaced where no defect is found or where the applicable "Diagnostic Report" is not provided with the part are subject to debit.
