Introduction
During Body Control Module (BCM) related service, the procedures below
are designated to set-up the BCM correctly. Before you start, read these procedures
     carefully and completely.

with the Theft Deterrent Re-learn  procedure.
 
NOTE:
                After the above procedure
    has  been    completed, personalization of the BCM defaults to a default
  setting.    Inform    the customer that the personalization settings must
  be set again.
Theft Deterrent Re-Learn
Perform this procedure under the following conditions:
|     •  | BCM has been replaced in the vehicle and the Setup New BCM procedure
has been successfully completed. | 
 
|     •  | Ignition key cylinder assembly has been replaced. | 
 
There are three ways of performing the Theft Deterrent Re-Learn procedure,
depending on the type of Techline equipment available:
- Techline terminal and a Scan Tool 
(quickest method).
 
- T-50 or T-60.
 
- Re-Learn without a Scan Tool 
or Techline equipment (slowest method).
