No communication w/ ECM
So, I was driving the other day when my gs300 died.
it’s cranks and and cranks, but my security light stays on when key is inserted and cranking ( I have 3 keys, none work). I go to pull codes, won’t connect to ecm. But it’s would power on my code reader.
I pulled ecm and it’s looks good.. no leaking capacitors that I could tell.
do you think I should replace ecm? I’ve checked fuses and just can’t really understand the disconnect from ecm and immobilizer engaged.
