purchased car from dealer a month ago,drove home 300k sat in car port for the month
got in car today , engine and tcl light stays on,car was perfect before! and started strait away,
seemed to lack power too ?
any clues?
I live in the bush long way from the dealer

2006 vrx with 67000k
full service history

I suspect your battery is on the way out, the 380 ECU is very sensitive to battery condition.
If it's the original battery which would now be around nine years old then it's way past due to replace it.
Even if it was replaced a few years ago, if it's now four+ years old I would be looking to replace it.

just drove the car again ,about10 k at 100kmh, the tcl light has gone off and have regular power back again, but engine light is still on
yes I suspect battery also,
will get it checked and post answer later
thanks

went to mechanic ,he scanned the ecu and came up with several codes all sensors,
he cancelled all and light went out,
he said because all were sensors and the month of non driving ,more than likely made the battery go below what the sensors need to function,and on start up took too much power from the system ,and triggered the faults,
did say battery may well be ok just no driving for a month,and the system needing a trickle voltage ,may have done it ,
advise; plug a battery charger when car isn't being used for a long period
cost! 2 bottles of coke,

How old is the battery?

As TreeAdeyMan said, if the battery isn't fully charged, if you hit the starter, it drops the system voltage quite low - and subsequently the ECU gets some strange readings and throws a light.

If the battery is almost fried, you might get by just by turning the key to on, pausing for 5 seconds while the ECU initialises, then turning it over.

But if the battery is more than three years old, you're just best off replacing it. Search other threads for advice. Essentially the biggest capacity, heaviest battery you can get in there, the better. The Century 75d23r is a good lead acid. Any of the AGM optimas are excellent, but pricey.
