Green cooling light flashing

[Akinkunmi]

I have a 2008 Yaris , the green cooling light flashes at continuously along with the PS light anytime I am driving.  The engine reev meter also goes off anytime the green cooling light is flashing  though the car works normally . My mechanic have checked but couldn't trace what it could be. 

Anyone with an idea to check.

Are the cooling fans kicking in, any strange noises, is the fan/aux belt tight ?

The fan kicks in at a good time... But this flashes can happen anytime while in motion sometimes when I enter a bumps it's will go back to normal ...

It may just be a pin fitment issue with the plug on the back of the cluster, i had an issue with my speedo would die randomly what was just a weak/dirty terminal - cleaned the plug and socket what it cured it

It could also be a dry joint inside the cluster - if you replace the cluster you will need to get it programmed to the car with the correct mileage

I'll like to give that a try but please what's a cluster so I can be sure theechanic is doing the right thing when I suggest this to him.

The gauges, also known as a gauge cluster or instrument panel

Flashing green, means the engine has not warmed up, if it's diesel that's normal, if it's petrol it may be the thermostat is stuck open, or a bad CTS
