Why do all the warning lights on my 2007 Holden Captiva turn on?

I own a 2007 Holden Captiva (diesel) and I have major instrumentation issues where as I have multiple warning lights coming on intermittently all at once. At the present moment I have ABS, DCS, AWD, ESP OFF, ESP ACTIVE, PARK ASSIST all showing whilst driving. I have taken car to Holden and they can't find problem, they have done a diagnostic check and it shows no faults. Any suggestions or advice would be appreciated.

The Holden Captiva has a terrible reputation in this department, and plenty of owners have had ongoing problems with the electronics in these vehicles which weren’t actually Holdens at all, but rather rebadged Daewoos. It’s a bit of a surprise to learn that a scan of the vehicle doesn’t show up any fault codes, but that also makes us think that perhaps you have a major failure of the vehicle’s body computer which controls all the functions you’re now being warned about on the dashboard. And if the body computer itself is in the process of failing, then it may not respond to the scanning process in a logical manner.

That said, the problem could be caused by something as simple as a poor earth in the car’s electrical circuitry, but experience with the Captiva suggests it will be something more complex and probably more expensive. Don’t rule out a failed electrical connection somewhere in the car’s wiring loom. The catch with the Captiva is that the cost of repairs is often greater than the retained value of the car itself, at which point you’re at an ownership cross-roads. The reality is that your car is probably only worth about $8000 (perhaps less) and a lot less as a trade-in. Spending thousands of dollars to fix it doesn’t add up to too many people.
