HELP

[Sarah032]

Probably time to take it to a Holden service centre. They have better diagnostic equipment than most places. You may find the ECM is on its way out. It's relatively common issue with the V6 VE.

Instead of an auto elec?

I would. Auto Electricians don't always have the needed diagnostic equipment that Holden does.

There are an awful lot of possibilities for these issues.

Sarah can check battery.
Check earths
Check the firewall behind the glove box to ensure the positive cable is secured tight and covered.
Clean all plugs on the engine harnesses.

I’d be suss on the engine harness connector having moisture in it. Not easy to reach.

I would call around dealerships and ask for an experienced Holden technician to take a look if you go down that path.

$120 min an hour. It would take hours to find it. If they say it’s something, ask them what evidence there was for that. They may be out the back guessing which parts to load in the parts canon.

I should add that there might be something in common with all those circuits. They may share something in the system. Maybe an earth. Maybe a plug. Those sorts of things need to be looked at by someone.

very few dealers have electrical experience now
a good auto elec is your best hope
but the only good ones are retired or booked solid
a dealer may have a recent tsb dealing with similar issues

Is the firewall hard to get to I don’t really know what it looks like

I guess I’ll do some research and try find a good one near the peninsula

Glove box out and it’s right up high just below the windscreen. Make sure negative battery terminal is disconnected first.

It’s a thick red cable with a black plastic cover. Give it a wiggle to make sure it’s secure and make sure it’s covered. (Mine wasn’t.)

was this a new bcm
