Body Control Module: Procedures
Body Control Module (BCM) Programming/RPO Configuration
1. The body control module (BCM) must be programmed with the proper RPO configurations. The BCM stores the information regarding the vehicle
options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of the features properly. Ensure that
the following conditions exist in order to prepare for BCM programming:
-
The battery is fully charged.
-
The ignition switch is in the ON position.
-
The data link connector (DLC) is accessible.
-
All disconnected modules and devices are reconnected before programming.
2. To setup a new BCM, use the Tech 2 in conjunction with the Saturn Service Stall System.
3. If the BCM fails to accept the program, perform the following steps:
-
Inspect all BCM connections.
-
Verify that the scan tool has the latest software version.
Passlock Learn Procedures
Important: If any module or device listed is replaced programming of the module must be done prior to performing the Passlock Learn procedure.
Perform the Learn Procedure if any of the following components have been replaced:
^
The body control module (BCM)
^
The ignition switch
^
The engine control module (BCM) (L81)
^
The powertrain control module (PCM) (L6I)
Important: After programming, perform the following to avoid future misdiagnosis:
1. Turn the ignition OFF for 10 seconds.
2. Connect the scan tool to the data link connector.
3. Turn the ignition ON with tbe engine OFF.
4. Use the scan tool in order to retrieve history DTCs from all modules.
5. Clear all history DTCs.
