My 2002 CRV: has an intermittent problem, after the key fob is used to lock the car the corner lights flash appropriately most the time and the vehicle locks. However on occasion, the corner lights will stay on. These are the same lights that turn on if you position the head light switch to the first position. If you are inside the car the alarm will sound if the lights are on, and if you play with the head light switch the light will eventually turn off.

I never had a problem with the turn signal lights; they are different then the corner lights.

There is nothing aftermarket about the car.

My question is does would replacing the ICU fix the problem or is there a different relay that needs to be replaced?
