Hello Robert,

What led you to replace the BCM?

Do you have a Tech2 scan tool?

Did you do the necessary programming of the BCM?


Customer: replied 9 months ago.
Hello and thank you for the reply, I replaced the bcm as the was no power coming to one of the fuel pump relay pinsI do not have a tech 2 scan toolI am using a autel maxisys 906btIt has all the functions to code but just says coding failed

Hi Robert,

I would more comfortable with a Tech2.

Interesting about the UEC environment identifier.

The one thing I have always done when replacing BCMs, PCMs, CIMs etc is to note setup, config, etc.

Can you do things like module presence check;

High speed, mid speed, low speed can-bus config with your scan tool?


Customer: replied 9 months ago.
I can do all that, they all say presentI might invest in a tech 2. Can tech 2 do a software update? I think this is what it needs
Expert:  Gary replied 9 months ago.

Yes, Tech2 can software update any module in this vehicle.

You also need to have access to the GM website for SPS programming.

Typically Tech2 is used for request current software from the vehicle.

It is then connected via an RS232 lead etc to your laptop.

Can be difficult to get this sort of stuff, if you aren't a GM dealer though.

How did the customer clear his codes, and was it running prior to this?


Customer: replied 9 months ago.
it was running fine, was in the garage to remove dpfI do not know which scan tool he used
Expert:  Gary replied 9 months ago.

Seems odd this has all happened after clearing codes.

That Tech2 looks like a good deal.

Way cheaper than they were near 20 years ago.

Hello Gary o have someone coming with tech 2 who can hopefully sort itAnother vauxhall can you help me or do I have to start a new question?Bauxhall antara, diesel,Was broken down and recovered it along with all these fault codes
Expert:  Gary replied 9 months ago.

Hi Robert,

I would say there is a wiring fault common to all three faults.

Can you open a new question since I have no info on that vehicle.

Kind regards
