Hi guys. Got this light on my 2007 Toyota Alphard Hybrid model. 
 

it’s intermittent and came on whilst in traffic. Then when I begin to drive it’s goes off. 
 

only been on twice on a 150 mile journey. But not sure what it’s for - some say it’s hybrid battery getting warm and some say it’s the catalyst converter getting hot/blocked but no definite answer 

 

can some please elaborate 

 

thanks 

Looks like the third from the bottom.

I hope this helps.

Thank you, it did cool down and has been fine since. 
 

Will get it looked at - drives superb tho. 

It’s worth checking the hybrid coolant pump 

Hi. Will this come up on a diagnostic machine? 
 

or is the only way to check by removing the cap off the coolant bottle
