2000 LeSabre BCM Suspect
The first thing the dealer would do is diagnostic's . Would not guess and just replace the BCM . Hooking up the factory Tech 2 scan tool an checking for DTC'S - diagnostic trouble codes , input data to the BCM etc.
(I have reason to believe the BCM in my 2000 LeSabre is bad ???? )you have no clue ! The BCM has nothing to do with gauges , insturment cluster ! Beside's you still would need to take it to the dealer because it would need to be programmed .
Leave this to a qualified repair shop . Plus the dash doesn't need to be taken apart to replace the BCM . Your vehicle actually has three modules for the body control system .
The body control system consists of 3 modules:
• The dash integration module (DIM)
• The instrument panel module (IPM)
• The rear integration module (RIM)
You have no idea what your messing with . Your best bet ,take it to a qualified repair shop ,and that doesn't always mean you need to take it to the dealer .
Each of the 3 body control modules integrate a number of functional systems under the control of a single module. Each of the modules is connected to the Class 2 serial data line. Many control signals are implemented by Class 2 messages.
Important: The air bag indicator light may remain ON after the DIM module is replaced, and during the programming procedure for the DIM, until after the procedure is completed and the ignition key is cycled OFF and ON .
• Before replacement, record the personalization settings to transfer to the new module (if they are available).
• After replacement of the DIM, perform the following procedure.
• In order to reprogram the DIM, perform the following procedure.
Using a scan tool, preform the New VIN Procedure.
Perform the Setup SDM Serial Number in DIM Procedure.
Using the scan tool, set the Point of Sale in the DIM module to the correct country.
Using the scan tool, configure the RPO option configuration.
Perform the vehicle personalization in order to reset the owner's desired personalization settings. Refer to Instrument Cluster, Gauges and Console.
Plus power door locks and windows are controlled by door module system , not body control system .The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door. The driver door module (DDM) is the master control for the door lock system but the rear integration module (RIM) contains the program that determines when the lock functions are permitted.
Mess with the wrong stuff an you will render your vehicle useless
cost to much to fix.
