Calais - Indicators sticking on when un/locking car remotely

[JBDrifter]

My Calais has recently sprung an issue whereby the left hand side indicators will sometimes stay on permanently after locking or unlocking the car remotely. I have done a bit of research and found the most common fault to be within the BCM. I just called my local Holden dealer and was quoted $600 for replacement of the BCM, which includes two new keys (as my current keys won't work with new BCM and apparently can't be programmed to it).

I was then asked if the problem had actually been looked at and confirmed that it was in fact the BCM, I said no and asked what else might cause this problem. He said 95% of the time it is the BCM, but sometimes it can be an issue with the BCM talking to the ECU. He said I should check the terminals at the BCM and ECU and make sure all the connections are good...

So, can anyone tell me exactly where I can find the ECU and BCM to be able to check the connections?

Cheaper option may be to read this forum about having your BCM repaired. I think the guy is Doctor Bob from down in Victoria, so perhaps send him a PM.

BCM failure

Just a suggestion.

Thanks mate, I PM'd him early this week and still waiting for a reply.

Last night I forgot to check if it had gone off when locking my car, and sure enough it hadn't. So I woke up to a dead battery this morning, hense I'm clutching at straws for a quick fix and hoping it might just be bad connection between the ECU and BCM. I just don't know wherre the ECU and BCM are located.
