SOURCE: My 2001 L200 Saturn has body control module

reprograming is very common, this is done all the time even with newer cars, some times cars new newer or diffrent programing installed in them and dealer is the only one that can do it unless someone has a dealer scan tool.As far as replacing it would depend on the problem and i think the dealer would of told them the computer was bad. hope this helps.

Where is the body control module located on a 1996 Oldsmobile Aurora.


You would need to see if any DTC'S -diagnostic trouble code's are stored in the BCM , That's the first thing that should be done . An a special type scan tool is needed , not a code reader for engine code's. If no code's ,checking power an ground circuits to the BCM need's to be done. Input an output test's have to be done as well . You need wiring diagrams , pin out diagram of BCM connectors . Need to know what all the BCM controls etc... Suggest you watch this videos .

I have a 03 envoy xl and replaced the old body control module with a used on how do I reset it?


It has to be programmed for sure if it can be used at all . Most GM vehicle do not allow used BCM'S . It will lock up with out proper vin number an anti-theft system information installed . Your best bet is call the dealer or an independent mobile technician in you area that does reprogramming . If I may ask what kind of problems were you having that makes you think the BCM needed to be replaced ? Was a Professional type scan tool used to see if the BCM was able to communicate ? Were power an grounds checked ? Fuse's etc... I see it a lot working at the dealer , not just GM vehicles either . Customer changed out module when it didn't need it.
If installing a replacement BCM, program the BCM. Refer to Body Control Module (BCM) Programming/RPO Configuration .
An you need a subscription on GM web site , GM scan tool or a J-2534 Pass-through Device programming tool .
The procedures below are designed to set-up the body control module (BCM) correctly during BCM related service. Before you start, read these procedures carefully and completely.
Important: The following procedures must be followed:
  1. Programming the BCM
  2. Programming Theft Deterrent System Components, if equipped with Passlock System
  3. Relearn Restraints ID
If you don't understand what this guy talks about , you really need to take it to the dealer.

How do I find diagnose issues with the body control module?


Absolutely. The ECM manages the engine and will display engine codes. The BCM is for non engine things. So I would not expect the BCM to display engine codes since they are separate computers.

There is a known problem with bad electrical connections at the plugs. Unplug the battery negative cable first. Then unplug the BCM wires and spray them with contact cleaner such as Deoxit R5. Do not use the type that melts plastic . Reconnect the wires and battery and try it again.

2005 avalanche Fog lights are staying on with


The fog lamps are computer controlled .the body control module (BCM) will energize the fog lamp relay control circuit. The BCM receives the park lamp ON signal from the interior park lamps supply voltage signal circuit.
DTC B2527 Front Fog Lamps Circuit Low
The body control module (BCM) monitors the front fog lamp switch signal circuit in order to determine when the fog lamp relay is to be energized. When the BCM senses that the front fog lamp switch signal circuit is grounded momentarily by pressing the fog lamp switch, the BCM energizes the fog lamp relay by grounding the fog lamp relay control circuit.

Your best bet , take it to the dealer . Could need BCM replaced , would need to do testing using the Tech 2 scan tool . A new BCM has to be programmed .

Body Control Module (BCM) Replacement
If the body control module (BCM) is replaced, the following procedures must be performed in the following order:
BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
Important: This procedure has to be performed only for vehicles equipped with the Passlock™ System.
Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent. A new BCM will learn the Passlock™ information automatically, but the powertrain control module (PCM) must still learn the theft information from the BCM.
