Calais BCM into Berlina - trip to holden required?

You will need to get the Calais BCM linked to your ECU. So a trip to Holden will be necessary.
I almost forgot, you will need a new key head if you can't get the one that goes with the Calais BCM.

 

it depends on what level the original BCM in the berlina is as to if it will fit,
if you fit it the car wont run, it needs to be linked.
why do you want to fit a calais one?
the BCM has nothing to do with engine or airbags

 

As Doctor Bob said,if you fit the BCM before going to Holden you will have to tow it there because it won't start until the BCM and ECU are security linked. The BCM is easy to fit, so I would weigh up what is cheaper, getting the car towed or letting Holden fit the BCM.

 

or book it in at holden and fit the bcm yourself in there driveway and they link the bcm and ecu together.

 

you cant use your excisting keyheads on the new bcm.
the bcm need sto be linked with Tech2 to the ecu.

ALSO
90 percent of the time a second hand BCM cannot be linked to a different ECU. needs to have the ECU the car came out of

i found out the hard way with a few BCM's i had when doing a v8 conversion.

 

i got a series one berlina and mine has remote deadlocks.

 

your the first person ive heard of that has ever had troubles with secondhand bcms not being able to link to an ecu, sounds like you had some stuffed bcm's

 

holden advised me as well that very rarely does a second hand BCM link properly

 

i have done hundreds of BCM swaps & have never had an issue linking them, not sure where that cones from, if the BCM is good it will link.

 

Hi to all this is my first time doing this i have no idea how to use this

anyways i have an issue with my vr calais it stopped working no securety light power windows and interior lights do not work it has two BCM`s
the dash BCM is a 293 purple sticker and the passenger BCM is a 522 TDM i changed the BCM under the dash it still has no power doesnt even crank the engine. what should i do
also i want to know the BCM on the passenger side does

thank you to who helps me out

If the BCM on the passenger's side is the one behind the kick panel then that is the ECU (engine computer).
It seems like the problem is not with the BCM if the one you replaced it with also doesn't work, I would suggest maybe a fuse or wiring problem. As mentioned earlier, if you change the BCM it needs to be linked to the ECU or the engine will not start.

 

no there is the ecu then the bcm which a small one then the bcm under the dash which is the larger one.. wot does the smaller one do the one next to the ecu

 

I have no idea but someone else will chime in eventually.

 

what is the bennifits of fitting a calais bcm? i have a berlina and it could be something i would like to do

 

You will quite possibly find that the wiring harnesses could be different meaning that it's more difficult than expected to change your BCM. Calais and Berlina are both LUX BCMs but quite often BCMs differ between series'.

 

damn povo pack utes

I have a VS series 1 "S" ute, which i am cleaning up and adding the bits and pieces to make the SS it should be (damn utes, got an option pack even more povo than the base model exec's).
I have picked up a MID spec BCM and have had the same problem, i installed it and all the goodies seem to work, like the indicators flashing when i i press the button on the key, power windows and locks not working yet as i need a couple of power dorrs to fit. but the engine will turn over and not start. I know about the linking of the bcm to the ecu.
The bit i found strange is that the engine will crank over, but wont start. i always thought the holden security system cut out the starter as well as the fuel and spark.
Has anyone come across this before?

Also, i have been thinking, is the software link stored in the memcal, or in a different area of the ECU? for example if i bought a replacement performnce style memcal will this cancel out the BCM to ECU link. kinda defeats the security idea but was just a thought

I acctually went to my holden service centre today and the crooks want 2 hours labour @ $102/hour, just so they can run a security check on my car before the hook it up to the tech one, pricks
