pull the carpet back and on the passager floor board the will be a plate remove it.
unfer the plate the ecu will have a small little round window turn the key to acc. and count the flashes.

count them write them down, then come back. a code will look like this for example. they consit of long flashes and short flashes

examples
long long long short short=32
long= 10
long short short short short=14
short=1


understand?
