The green 'D' light on the dash panel might flash on a CRV 2002 Sport when it is in motion, because it is telling the driver that the transmission needs to shift to a higher gear. If the vehicle is equipped with Overdrive, this gear should be used unless towing a trailer. If the vehicle has a manual transmission, it is telling the driver to shift to a higher gear.

If it flashes red it means it has low battery, if it flashes green it means the battery is okay!

When engaged in four wheel drive light flashes but wont engage the shaft locks but no four wheel actuator is not pushing out in my 97 tahoe?
There is aproblem with either the transmission or the overdive unit.
Have it checked for codes, you have some possibly serious issues.
you need a new transfer case
It usually means your transmission is going bad. Is there a code (Check engine light on) with the flashing light?

Sounds like a trip to the garage to me. Make sure it is in neutral when switching from low to high, if not it will flash like you described.
