MICU Electrical Issues
We have 2006 1.8L EX civic in the family which has started to give us problems.
We bought the car last year and when we bought it, it didn't used to start (clicks) but was ok using jump starters.
We decided to change the battery and earth leads,march last year, since then it has been fine if being driven everyday, when we leave it for a few days the battery goes dead and does not start, just clicks.
Since then we left it for a over 3 days and the battery went totally dead and needed jump. my brother jumped it but left keys in ignition and now its flashing green key, we then decided to use multi meter and find out why it was draining and turned out to be bluetooh unit, we disconnected it as well as the siren as it used to sound as soon as battery was connected.
We managed to get it towed to local Honda as i read from posts, the keys need to be recoding.
Now after 4 days of it sitting there, they managed to recode the keys but are saying that the when the keys are withdrawn the immobiliser loses the key that are programmed and they cant understand why.
Today they rang and told us after they have contacted Honda technical the MICU seems to be faulty, they will put another MICU in and check the keys.
Could this be the case, Im reluctant to believe them but i don't understand why or how the MICU could go all of a sudden.
Any replys or comments would be very much appreciated,
little upset as the car is nice
