Have a request from someone who knows the procedure for reprogramming a BCM on a C6.

I swapped in a replacement BCM I got from an online recycling place and went to the dealer to get it reprogrammed. I'm still having my airbag light on and will have to go back as my tuner used their Tech2 and it's throwing a B1001 DTC. So I'll go get this fixed.

However, in my reading of the tech manual, it states the procedure, in simple terms, of how the BCM is programmed. In one section it mentions plugging in the RPO codes for that car and finally the VIN.

My request is: Can/Will someone list to me step by step how this is done from start to finish and which RPO codes are available for entry? In other words, what are all the options available for programming into the BCM? I am also working on a project that involves the factory Nav and the class2 data bus. I think my project worked on my car (did not have nav as an RPO) because the replacement BCM WAS programmed with the Nav option even though I never had the factory Nav in the car.

I was pretty sure the scan tool has all the information in it for programming the BCM. This is what eSi had to say...

Body Control Module (BCM) Programming/RPO Configuration
Introduction

A new 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. The Tech 2 software will automatically prompt you with the RPOs available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
•
The battery is fully charged.


•
The ignition mode switch is in the ON position.


•
All disconnected modules and devices are reconnected before programming.



Important: The following procedures must be performed in the order listed:

1. BCM Setup
2. BPP Sensor Calibration

BCM Setup

Important:
•
After the procedure is completed, the personalization settings of the BCM are set to a default setting. Inform the customer that the personalization must be set again.


•
Always perform this procedure after BCM or SDM replacement.


•
A new BCM may set DTC B1001 00 before performing this procedure. This is a normal condition and DTCs will clear after the procedure is performed.

During this procedure, besides RPO configuration, the BCM relearns the restraints ID.
BPP Sensor Calibration

Important:
•
Always perform this procedure after the BCM was reprogrammed or after the brake pedal position sensor was replaced.


•
Do not press the brake pedal during the programming procedure.


•
A current DTC C0278 set by BCM before performing this procedure is a normal condition. The DTC will clear after the procedure is performed.

I was curious to know which RPO codes it promts for. I'm sure the BCM doesn't care which wheels you have (chrome or painted) but it might care if you have nav or Onstar. That's what I'm trying to find out.

You'd pretty much have to have a Tech2 in front of you to list the steps. It's been about a year since I programmed mine and afterward sold the tech2.

My 08 was not difficult at all. We plugged into GM Techline and the car, entered the VIN and it pretty much self programmed to the car.

We programmed the Security and brake information and was good to go after about 30 minutes.

Someone with a tech2 should chime in with the manual process if not plugged into techline.

 

Do you have the factory Nav in your car? Do you recall if that was part of the process when hooking to the Tech2?
