Further Update......

After letting the vehicle sit for 30minutes, it would restart
But again, with the DSC, ABS and Warning Light on in Red

I unlocked the Cluster Menu, checked voltage, was 12v
I then went to Menu position 21 and Reset the OBC (not sure why i did this)

All the warnings lights remained on (DSC, ABS and Warning)
Drove the vehicle around the block and parked back in driveway

Turn vehicle off
Removed key, waited 20seconds
Inserted key, turned to position 2, No lights on dash (at this point, i knew vehicle would not start)
Turned the key to start, nothing, no cranking, nothing, total lock out.

Repeated this process 2 more times
Same outcome, now cluster lights, no cranking.

Yet i know, if i let the vehicle sit for 30minutes it will start again


Im lost with this one, time for the 200 Series Landcruiser

Next i will go and get my Laptop with PA Soft OBD2 software and a new Battery i have in workshop
All i can think of right now.

In relation to the vehicle not starting or displaying the warning lights on dash prior to starting
I have been reading about the IVM module

Not sure if this related to our Diesel version or not?

Just retested my Battery voltage, 12.14v
It shouldn't be that low in my books..... It was on a charger all night, it was 12.8v only 1 hour ago.

I think wpoll is right, this Battery has gone defective after only 18 months!

What is strange, is we have had flat or low batteries many time in the passed, it has NEVER shown up the DSC, ABS or Warning lights
It just displays slow cranking and noticeably slower central locking operation.
This Battery, even with it low voltage, still cranks fine and central looking works fast and snappy

Update....

Went down after letting the vehicle sit
Turned key, all dash light lit up, crack and started perfecting (albeit with the DSC, ABS and Warning still on)
Drove vehicle in garage at home,
Turned off and disconnected the battery

Battery Voltage once removed from vehicle was 12.56v (was i'd say was normal)
But obviously it drops the 12.14v when connected to vehicle because the electric load.
